Panasonic N210076717AA 3-Head Holder Helical Spring for CM402 SMT Mounter

The N210076717AA 3-Head Holder Helical Spring is a precision mechanical replacement component used in the holder assembly of Panasonic CM402 SMT placement equipment. Available parts references identify N210076717AA as a spring associated with the CM402 H3 or 3-head holder mechanism.

During normal SMT production, the placement head performs continuous repetitive movement at high speed. Small mechanical parts inside the head assembly therefore need to maintain stable elasticity, accurate return movement, and consistent mechanical response. When the original spring becomes fatigued, deformed, damaged, or loses its restoring force, the holder mechanism may no longer operate smoothly.

Replacing the worn component with the correct N210076717AA spring can help restore normal holder movement and maintain dependable machine operation. This part is suitable for SMT factories, maintenance departments, equipment service companies, and spare-parts distributors maintaining CM402 production equipment.

The compact design makes it an economical maintenance item that can be stocked as part of a preventive maintenance inventory.

Cause

Holder springs operate under repeated compression and release cycles during machine operation. Although the component is small, its condition can directly affect the mechanical movement of the holder assembly.

Common reasons for spring replacement include:

A spring normally works together with other holder and head components. Therefore, a problem appearing around the placement head should not automatically be attributed to the spring alone.

Maintenance technicians should inspect the complete related assembly before replacing parts.

Typical areas worth checking include:

• Holder movement
• Spring condition
• Nozzle holder assembly
• Bearings
• Pneumatic connections
• Mechanical fasteners
• Related head components
• Signs of contamination or excessive wear

Correct diagnosis helps prevent unnecessary part replacement and reduces machine maintenance time.

Solution

When inspection confirms that the original holder spring is worn, damaged, deformed, or no longer providing stable mechanical return, replacement with the correct part number is a practical maintenance solution.

The N210076717AA is identified in available SMT parts references as a spring used in the CM402 holder or H3 holder assembly.

For reliable replacement, technicians should verify the following before installation:

A correct replacement helps maintain consistent return movement in the holder mechanism.

For production environments where CM402 machines operate continuously, keeping several holder springs in maintenance stock can also help reduce unexpected downtime.

Specifications

Available parts listings consistently associate N210076717AA with the CM402 holder spring application.

Product Function

The spring provides mechanical restoring force inside the related holder mechanism.

During machine operation, components in the placement head move repeatedly according to the placement sequence. The spring compresses or changes position as required by the mechanism and then provides restoring force to support the return movement.

Its main functional objectives include:

Because the spring works as part of an assembly, correct installation position and orientation are important.

Application

The N210076717AA spring is primarily used for maintenance of Panasonic CM402 placement equipment, specifically in the relevant 3-head holder mechanism.

Typical applications include:

SMT Production Line Maintenance

Suitable for electronics manufacturing factories operating CM402 pick and place machines.

Placement Head Repair

Used when technicians are servicing the related holder mechanism and the original spring shows signs of fatigue, deformation, damage, or reduced elasticity.

Preventive Maintenance

The spring can be stocked together with other frequently serviced mechanical head components to support planned maintenance.

Emergency Spare Parts Inventory

SMT factories can keep N210076717AA in their spare-parts inventory to reduce waiting time when replacement becomes necessary.

Equipment Refurbishment

Suitable for servicing older CM402 equipment where mechanical head components require inspection and replacement.

Typical Industries

The component can be used in SMT production environments serving industries such as:

Its purpose remains the same across these applications: supporting reliable operation of the corresponding CM402 holder mechanism.

How It Works

The N210076717AA is a mechanical spring used within the holder structure.

When the related holder mechanism moves during a machine cycle, the spring is mechanically loaded. This stores mechanical energy within the spring.

As the mechanism returns, the spring releases this stored energy and provides restoring force to assist the component in returning toward its designated position.

The operating sequence can be simplified as follows:

Because this sequence can occur continuously during production, the spring experiences repeated mechanical cycles.

Over long operating periods, fatigue can gradually reduce spring performance. This is why periodic inspection of small mechanical components is important during placement-head maintenance.

Signs That Replacement May Be Required

Technicians may consider inspecting the spring when abnormal mechanical behavior appears around the related holder assembly.

Possible symptoms include:

• Holder movement becoming less smooth
• Spring appearing visibly deformed
• Reduced mechanical return force
• Spring damage discovered during scheduled maintenance
• Irregular movement after long operating periods
• Mechanical wear around related holder parts
• Spring no longer maintaining its original shape

These symptoms should be used as inspection references rather than as a diagnosis by themselves.

Other mechanical or pneumatic components can produce similar operating symptoms.

How To Choose

Selecting the correct spare part should be based primarily on the original machine configuration and part number.

1. Confirm the Part Number

Check that the required number is:

N210076717AA

This is the most important identification information.

2. Confirm the Machine

Verify that the equipment being serviced is a compatible CM402 configuration.

3. Confirm the Head Configuration

This spring is associated with the CM402 H3 or 3-head holder application in available parts references.

4. Compare the Existing Component

Before ordering, compare the removed spring with the required replacement whenever possible.

5. Check Related Components

If the spring failed because of abnormal mechanical loading, replacing only the spring may not fully solve the problem.

Inspect the holder, bearings, fasteners, and other related mechanical parts.

Ordering Verification Guide

For faster quotation and more accurate supply, buyers can provide:

Providing a clear photo is especially helpful when the machine has been modified or rebuilt.

Maintenance Recommendations

Small head components should be handled carefully.

Before installation:

• Shut down the equipment according to factory maintenance procedures.
• Confirm the exact installation location.
• Keep the work area clean.
• Avoid stretching or deforming the spring unnecessarily.
• Inspect the surrounding holder mechanism.
• Remove contamination from the relevant mechanical area.
• Confirm that mating components move normally.
• Reassemble according to machine maintenance procedures.

After replacement, manually or diagnostically verify the related mechanical movement before returning the machine to full production.

Why Keep This Part in Stock

The cost of a small mechanical spring is normally minor compared with the production loss caused by extended SMT machine downtime.

For factories operating CM402 equipment, maintaining a practical spare-parts inventory offers several advantages:

Frequently used mechanical components are especially suitable for maintenance inventory because they are compact and easy to store.
