4022 516 12300/402251612300 Sprocket wheel for Assembleon ITF2 feeders

The 4022 516 12300 sprocket wheel, also referenced as 402251612300, is a mechanical feeder component designed for the tape-advance mechanism of compatible Assembleon ITF2 SMT feeders. During feeder operation, the sprocket teeth engage the regularly spaced perforation holes along the carrier tape and convert feeder drive movement into controlled tape indexing. This controlled movement allows each component pocket to advance toward the programmed pickup position.

Because the sprocket operates repeatedly throughout SMT production, tooth wear, contamination, deformation, or mechanical misalignment can eventually affect tape advancement. Replacing a confirmed worn sprocket can help restore smoother tape movement without replacing the complete feeder.

This component is suitable for SMT factories, feeder repair workshops, maintenance departments, equipment refurbishers, and spare-parts distributors maintaining ITF2 feeder systems. For accurate ordering, customers should provide 4022 516 12300 / 402251612300, feeder width, quantity, and feeder identification information.

A sprocket wheel is a working mechanical component rather than a passive feeder accessory. Its teeth repeatedly enter the carrier-tape indexing holes whenever the feeder advances tape.

Long-term production can therefore create gradual wear.

Common causes include:

A feeder requiring inspection may show:

• Irregular carrier-tape advancement
• Tape slipping during indexing
• Damaged tape perforation holes
• Repeated feed-position variation
• Unstable component presentation
• Unusual resistance during tape movement
• Intermittent feeder errors
• Visible sprocket tooth damage
• Excessive wear around the indexing mechanism

These symptoms do not automatically mean the sprocket wheel is defective. The complete feeder mechanism should be checked because motors, shafts, sensors, guides, controllers, and tape-loading conditions may produce similar problems.

When inspection confirms that the existing sprocket wheel has worn or damaged indexing surfaces, replacing it with the correct 4022 516 12300 / 402251612300 component can restore the mechanical interface between the feeder drive and the carrier tape.

A recommended maintenance sequence is:

Check whether the tape is correctly routed and whether its perforation holes are damaged.

Look for:

• Rounded teeth
• Broken teeth
• Uneven tooth wear
• Contamination
• Mechanical deformation
• Excessive movement
• Incorrect alignment

The sprocket works as part of a system. Inspect the associated:

• Main shaft
• Feeder motor
• Sprocket sensor
• Tape guide
• Tape cover
• Drive mechanism
• Controller
• Mechanical mounting points

Install the correct replacement component according to suitable feeder maintenance procedures.

Run multiple indexing cycles before returning the feeder to production.

Confirm that carrier-tape pockets advance consistently and components reach the expected pickup position.

This targeted maintenance approach helps avoid unnecessary replacement of the complete feeder when the problem is limited to the indexing mechanism.

ITF2 feeders are available in multiple tape-width configurations. Identifying the correct feeder version is useful when confirming spare-part requirements.

Compatibility Note: The table identifies members of the ITF2 feeder family. Exact applicability of part number 4022 516 12300 should be confirmed against the feeder configuration and existing component before ordering.

When diagnosing an indexing problem, several related feeder parts may need inspection.

This table is particularly useful for feeder repair facilities because an indexing fault may involve more than one mechanical or electrical component.

The sprocket wheel is suitable for maintaining compatible ITF2 tape feeders used in automated PCB assembly lines.

A correctly operating tape-advance mechanism helps maintain:

• Predictable carrier-tape movement
• Consistent component presentation
• Stable feeder cycling
• Reliable pickup preparation

Specialist feeder repair companies can use the part when refurbishing feeders with confirmed sprocket wear.

Instead of replacing an entire feeder assembly, repairing the specific worn mechanism may reduce maintenance cost.

Factories operating many feeders often keep high-use mechanical components in spare-parts inventories.

A sprocket wheel can be stocked alongside:

• Tape guides
• Motors
• Sensors
• Shafts
• Controllers
• Covers
• Drive components

This helps maintenance teams react quickly when feeder wear is detected.

Used feeders frequently require inspection before returning to production.

The sprocket mechanism should be checked for wear, contamination, damaged teeth, and rotational stability.

If required, replacing worn sprocket components can form part of the refurbishment process.

The component may support feeder maintenance in:

The component reel is loaded into the feeder, and the carrier tape is routed through the appropriate tape path.

The sprocket teeth align with the carrier-tape perforation holes.

The sprocket creates a positive mechanical engagement with the tape.

This is important because the feeder must advance the tape by a controlled distance rather than relying on friction alone.

When the feeder receives an advance command, its drive mechanism causes the sprocket system to rotate.

The rotating sprocket pulls or advances the tape through the feeder path.

The component pocket therefore moves toward the pickup area.

Once indexing is complete, the next electronic component is positioned for pickup by the placement machine.

The process repeats continually during production:

Drive Command → Sprocket Rotation → Tape Indexing → Component Presentation → Pickup

Because thousands of indexing cycles may occur during production, mechanical consistency is important.

The sprocket does not directly place electronic components. Its core function is to control carrier-tape advancement inside the feeder, which indirectly supports repeatable component presentation at the pickup position.

These formats refer to the same product identification.

Verify that your unit belongs to the ITF2 feeder family.

Components from other feeder generations may appear similar but should not be assumed interchangeable.

State whether the feeder is:

• 8 mm
• 12 mm
• 16 mm
• 24 mm
• 32 mm
• 44 mm
• 56 mm

This helps suppliers verify the complete feeder configuration.

A clear photo of the feeder identification label is recommended.

It can help verify:

• Feeder series
• Feeder width
• Part reference
• Revision
• Configuration

For higher-order accuracy, provide photos of:

• Front side
• Rear side
• Tooth profile
• Shaft mounting area
• Installed position

Do not replace the sprocket solely because the feeder has an indexing error.

Check the full tape-advance system first.

The clear references 4022 516 12300 and 402251612300 make purchasing and inventory identification straightforward.

Suitable for restoring the indexing mechanism without automatically replacing a complete ITF2 feeder.

Useful for feeder repair workshops, SMT production maintenance teams, and spare-parts inventories.

Correct sprocket engagement helps maintain controlled advancement of carrier tape toward the pickup position.

Buyers can submit part number, feeder width, quantity, and photographs for compatibility checking before shipment.

Typical inspection procedures can include:

1. Product appearance inspection
2. Sprocket tooth condition check
3. Part-number verification
4. Dimensional comparison where applicable
5. Quantity confirmation
6. Protective packaging inspection

For customers replacing an existing sprocket, sending photos of the removed component is recommended before order confirmation.

The sprocket wheel engages carrier-tape perforation holes and transfers feeder drive movement into controlled tape advancement. This allows the next component pocket to move toward the placement machine's pickup position.

Yes. 402251612300 is the compact numerical format, while 4022 516 12300 is the spaced format commonly found in feeder spare-parts references.

No. This listing is for the sprocket wheel spare component only. A complete feeder includes motors, sensors, controllers, tape guides, covers, and other mechanical assemblies.

Provide the part number, ITF2 feeder width, feeder identification label, required quantity, and preferably photos of the existing sprocket wheel. These details allow more accurate configuration checking.

Replacement should be considered when inspection confirms damaged or excessively worn sprocket teeth, abnormal rotation, poor carrier-tape engagement, or indexing instability directly related to the sprocket mechanism.
