FUJI H4130E NSK 608Z Metal Shielded Bearing with 8 mm Bore and 22 mm Outside Diameter for SMT Machines

FUJI H4130E NSK 608Z Shielded Bearing for CP6 CP7 Machines

The FUJI H4130E NSK 608Z bearing is a compact deep groove ball bearing supplied for rotary support, mechanical transmission, roller, shaft, and related moving positions in compatible FUJI SMT placement equipment. With a standard dimensional configuration of 8 mm inner diameter, 22 mm outer diameter, and 7 mm width, the bearing provides a practical replacement option for worn or damaged H4130E components.

Its deep groove raceway design supports smooth rotation while handling mainly radial loads and limited axial loads generated during normal machine operation. The metal-shielded structure helps reduce the entry of dust and foreign particles while retaining the factory-applied lubricant.

H4130E is commonly referenced for FUJI CP-series machines, including selected CP6, CP642, CP643, CP7, CP742, CP743, and CP842 configurations. Because installation positions and bearing suffixes may vary, buyers should confirm the old bearing marking, machine model, assembly location, and required shield arrangement before ordering.

Product Identification

Key Product Benefits

Compact Standard Dimensions

The 8 × 22 × 7 mm dimensional format allows the bearing to fit compact rotating assemblies where installation space is limited. Its standardized 608-series dimensions make physical identification and replacement comparison easier.

Smooth Rotary Support

The deep groove raceway and rolling-ball structure reduce sliding friction between the shaft and housing. This supports smoother movement than a worn, seized, contaminated, or incorrectly fitted bearing.

Stable Mechanical Transmission

A correctly selected H4130E bearing helps maintain shaft position and rotational consistency. Stable bearing support is important in SMT equipment because irregular movement can influence mechanical timing, vibration, feeder operation, and placement repeatability.

Metal-Shielded Construction

The shielded configuration provides a protective barrier against larger dust particles and foreign material while keeping lubricant inside the bearing. This construction is suitable for enclosed or semi-enclosed mechanical positions where low friction and compact size are required.

Maintenance-Friendly Replacement

The bearing can be replaced as part of preventive maintenance, machine refurbishment, or failure repair. Replacing a worn bearing before complete seizure may help protect the shaft, housing, pulley, roller, and surrounding components.

Suitable for SMT Production Environments

The H4130E bearing is intended for compatible FUJI electronic component placement equipment. It can be used by SMT factories, maintenance departments, machine rebuilders, equipment dealers, and spare-parts service companies.

Cause: Why Bearing Problems Occur

Bearings operate continuously under rotating load, assembly pressure, vibration, temperature variation, and contamination exposure. Over time, these conditions can damage the raceway, rolling elements, shield, cage, or lubricant.

Common Causes of H4130E Bearing Failure

Typical Failure Symptoms

A bearing may require inspection or replacement when one or more of the following symptoms appear:

• Unusual mechanical noise during machine operation.
• Roughness when the shaft or roller is turned manually.
• Increased vibration around the bearing position.
• Abnormal heat near the rotating assembly.
• Visible rust, discoloration, shield damage, or grease leakage.
• Excessive radial or axial play.
• Irregular movement of the supported shaft or roller.
• Repeated mechanical alarms related to the affected assembly.
• Reduced machine stability after long operating periods.
• Bearing seizure or resistance during rotation.

Bearing symptoms should not be evaluated alone. Similar problems may also be caused by a bent shaft, worn housing, loose fastener, damaged belt, incorrect tension, contaminated roller, or assembly misalignment.

Solution: Replacing the Worn H4130E Bearing

Replacing a worn bearing with a correctly matched FUJI H4130E NSK 608Z component can restore smooth mechanical support and reduce unwanted friction. The replacement should match the original bearing dimensions, shield configuration, clearance suffix, machine position, and installation requirements.

Recommended Replacement Process

A bearing should never be installed by applying uncontrolled impact through the rolling elements. When fitting the bearing onto a shaft, installation force should normally be applied to the inner ring. When fitting it into a housing, force should normally be applied to the outer ring.

Technical Specifications

The official NSK reference for the standard 608 series lists an 8 mm bore, 22 mm outside diameter, 7 mm width, approximately 3,650 N basic dynamic load rating, approximately 1,370 N basic static load rating, and reference speeds up to 34,000 min⁻¹ with grease lubrication. These are standard-series reference values rather than guaranteed operating values for every H4130E suffix or machine installation.

Important Technical Note

The designation 608Z generally identifies a bearing with a metal shield, while 608ZZ, 608ZZ1, or related designations indicate different shield or manufacturer-specific configurations. Some commercial H4130E records identify the bearing as 608Z, while others list 608ZZ or 608ZZMC3E.

For this reason, the supplied bearing must be confirmed against:

• The complete marking on the original bearing.
• The number of metal shields.
• Internal clearance or suffix requirements.
• The FUJI machine model.
• The assembly position.
• The shaft and housing dimensions.
• The relevant machine parts manual.

Do not select the bearing using only the base number “608” when the complete suffix is available.

Application

The FUJI H4130E NSK 608Z bearing is used as a mechanical support component in compatible electronic component placement machines. It may be installed in rotary assemblies where a compact bearing is required to support a shaft, roller, cam, pulley, transmission element, or related moving component.

Typical Equipment Applications

Compatible Machine References

H4130E is commonly marketed for selected FUJI machine configurations, including:

• FUJI CP6.
• FUJI CP642.
• FUJI CP643.
• FUJI CP7.
• FUJI CP742.
• FUJI CP743.
• FUJI CP842.
• Other FUJI assemblies using the same H4130E bearing specification.

Compatibility must be verified because the same machine family can contain different mechanical revisions, assembly options, production years, and bearing suffixes.

Recommended Use Scenarios

Scheduled Preventive Maintenance

Factories operating high-volume SMT lines can keep H4130E bearings in their maintenance inventory. Replacement may be scheduled when inspection shows abnormal noise, play, friction, contamination, or visible damage.

Emergency Machine Repair

When a bearing fails unexpectedly, a verified replacement can reduce equipment downtime. For urgent quotations, buyers should provide the bearing marking, machine model, required quantity, and clear photographs.

Machine Overhaul

During a complete CP-series machine overhaul, technicians may inspect bearings throughout the mechanical system. Bearings showing roughness, corrosion, excessive clearance, or shield damage should be replaced.

Second-Hand Equipment Refurbishment

Used SMT machines often require mechanical inspection before installation at a new factory. Replacing worn bearings can improve operating stability and reduce maintenance risk during recommissioning.

International Spare-Parts Supply

The compact size of the H4130E bearing makes it suitable for international express delivery. It can be packed individually or combined with other FUJI machine parts in one shipment.

How It Works

A deep groove ball bearing consists mainly of an inner ring, outer ring, rolling balls, cage, lubricant, and protective shield. The inner ring normally fits around the shaft, while the outer ring is positioned inside the housing.

When the shaft rotates, the balls roll between the inner and outer raceways. Rolling contact produces less friction than direct sliding contact, allowing the shaft or roller to move more efficiently.

Operating Principle

Load Transmission

Radial load is transferred from the shaft to the inner ring, through the balls, and into the outer ring and housing. A deep groove bearing can also accept limited axial force in either direction, but the actual permitted load depends on speed, fit, lubrication, alignment, temperature, and operating conditions.

Importance in SMT Equipment

SMT placement machines rely on repeated, controlled mechanical movement. A bearing with excessive play or roughness can introduce vibration and irregular movement. A correctly matched bearing supports stable machine operation by maintaining smoother rotation and more consistent shaft positioning.

Performance Advantages

Low-Friction Rotation

The rolling-ball design reduces mechanical resistance and supports smooth movement in compact assemblies.

Small Installation Footprint

The 8 × 22 × 7 mm dimensions provide rotary support without requiring a large housing or shaft structure.

Radial Load Support

The deep groove raceway is suitable for supporting radial loads commonly generated by rotating shafts, rollers, and transmission mechanisms.

Limited Bidirectional Axial Support

The raceway geometry can accept limited axial load from either direction when the bearing is correctly installed and operated within its specified conditions.

Reduced Contamination Exposure

The metal shield helps limit the entry of larger particles while retaining lubricant. It is not equivalent to a fully contact-sealed bearing and should not be exposed to heavy liquid contamination.

Simple Maintenance Strategy

Because the bearing is a replaceable mechanical component, maintenance teams can inspect and replace it without changing the complete machine when surrounding parts remain serviceable.

Installation Guidelines

Correct installation has a major effect on bearing performance. A new bearing can fail quickly if it is installed with excessive force, contamination, misalignment, or an incorrect fit.

Before Installation

• Confirm that H4130E is the required FUJI part number.
• Check the complete NSK bearing marking.
• Measure the bore, outside diameter, and width when necessary.
• Compare the number and position of shields.
• Inspect the shaft for wear, scratches, corrosion, or bending.
• Inspect the housing for looseness, deformation, or contamination.
• Prepare suitable bearing fitting and removal tools.
• Keep the new bearing sealed until installation.
• Clean the working area before opening the package.
• Follow the machine manufacturer’s maintenance procedure.

During Installation

• Do not strike the bearing directly with a steel hammer.
• Do not transfer pressing force through the balls.
• Apply force only to the ring receiving the interference fit.
• Keep the bearing square to the shaft and housing.
• Avoid damaging the shield.
• Do not remove the factory grease without a technical reason.
• Do not mix dirty and clean installation tools.
• Confirm that spacers and retaining components are correctly positioned.
• Tighten related fasteners according to the equipment procedure.
• Turn the assembly manually before restoring machine power.

After Installation

• Confirm that rotation is smooth and free from binding.
• Check the assembly for excessive play.
• Run the machine at a controlled speed.
• Listen for clicking, scraping, or irregular noise.
• Observe the bearing area for abnormal heat.
• Recheck fasteners after the initial test when required.
• Record the maintenance date and replacement position.
• Keep the removed bearing for failure analysis if necessary.

Maintenance Recommendations

The H4130E bearing is generally treated as a replaceable component. Maintenance intervals depend on operating hours, speed, load, environment, installation accuracy, and machine condition.

Storage Recommendations

• Store the bearing in its original protective package.
• Keep it in a clean, dry, temperature-controlled area.
• Avoid direct contact with water or corrosive chemicals.
• Do not place heavy items on top of the bearing package.
• Do not open the package until installation.
• Use first-in, first-out inventory management.
• Label the stock with the FUJI and NSK reference numbers.
• Separate new, used, repaired, and removed components.
• Avoid handling the bearing with wet or dirty hands.
• Inspect long-stored inventory before installation.

How to Choose the Correct Bearing

Selecting the correct bearing requires more than matching the dimensions. Two bearings can have the same 8 × 22 × 7 mm size but differ in shield arrangement, clearance, lubrication, precision, cage design, or operating specification.

Selection Checklist

608Z and 608ZZ Selection

A 608Z and a 608ZZ bearing normally share the same primary dimensions, but their shield arrangements differ. The shield configuration can affect contamination protection, lubricant retention, installation orientation, and resistance.

If the original component is marked 608ZZ, do not automatically replace it with 608Z without confirming the technical requirement. Likewise, suffixes such as MC3E may indicate an internal specification that should be matched when required.

FAQ

1. What is the FUJI H4130E bearing used for?

The H4130E bearing is used to support rotary movement in compatible FUJI SMT machine assemblies. Depending on the machine configuration, it may operate with a shaft, roller, cam, pulley, transmission mechanism, or other rotating component. The exact installation position should be checked in the machine parts manual or confirmed from the removed component.

2. What are the dimensions of the NSK 608Z bearing?

The standard 608-series bearing dimensions are 8 mm inner diameter, 22 mm outer diameter, and 7 mm width. Buyers should still measure the old part and check the complete suffix because bearings with identical external dimensions can have different shields, internal clearances, lubrication, and performance specifications.

3. Is H4130E compatible with all FUJI CP6 and CP7 machines?

H4130E is commonly referenced for selected CP6, CP642, CP643, CP7, CP742, CP743, and CP842 equipment. However, compatibility cannot be guaranteed from the machine family alone. Please provide the exact machine model, serial number, installation position, old-bearing marking, and photographs before ordering.

4. What is the difference between 608Z and 608ZZ?

Both normally use the same 8 × 22 × 7 mm base dimensions. The primary difference is the metal-shield arrangement. A Z designation generally identifies one shield, while ZZ identifies shields on both sides. Additional suffixes may indicate clearance, lubrication, or manufacturer-specific details. Always match the complete original marking.
