402-24502 Coupling Rubber Ring for Juki DU-1481 Industrial Sewing Machine Parts

The 402-24502 Coupling Rubber Ring is a replacement part designed for the coupling system of Juki DU-1481 industrial sewing machines.

Installed between the upper shaft coupling and motor coupling, this elastic rubber ring helps transmit rotary motion smoothly, reduce direct metal contact and support stable machine operation.

Please send your machine model, original part number, product photos and required quantity before ordering. Our team will help confirm compatibility and provide a complete quotation with suitable delivery options.

The motor coupling system is responsible for transferring power from the sewing machine motor to the upper shaft.

Part number 402-24502 is the coupling rubber ring installed inside the coupling assembly of the Juki DU-1481 industrial sewing machine. It works together with the upper shaft coupling and motor coupling to support smooth and stable power transmission.

During long-term operation, the rubber ring may become hardened, cracked, compressed or worn. A damaged coupling ring can cause excessive vibration, abnormal operating noise, unstable power transmission or increased movement between the motor and upper shaft.

Replacing the worn coupling rubber ring helps restore the normal connection between the motor coupling and upper shaft coupling. It can also help reduce unnecessary vibration and prevent direct impact between the metal coupling components.

This product is suitable for garment factories, upholstery manufacturers, sewing workshops, industrial sewing machine maintenance companies and spare parts distributors.

Required before ordering

The 402-24502 coupling rubber ring is positioned between the upper shaft coupling and the motor coupling.

Its main function is to help transfer motor rotation to the upper shaft while providing a flexible connection between the metal coupling components.

The elastic structure helps absorb minor vibration and impact generated during machine startup, stopping and continuous sewing operations.

A correctly fitted coupling rubber ring supports smoother rotation, more stable power transmission and reliable industrial sewing machine performance.

• Accurate Replacement Reference

  The product is supplied according to part number 402-24502 for easier identification and compatibility checking.

• Elastic Rubber Structure

  The flexible rubber material provides cushioning between the upper shaft coupling and motor coupling.

• Stable Power Transmission

  It helps maintain consistent rotary movement between the motor and upper shaft during sewing operations.

• Reduced Metal Contact

  The rubber ring separates the connected metal coupling components and helps reduce direct impact during operation.

• Convenient Maintenance

  The coupling rubber ring can be replaced during routine machine maintenance without replacing the complete coupling assembly when the other components remain usable.

• Quality Inspection

  The appearance, shape and basic fit of the product are checked before packing and shipment.

1. Replacement may be required when the sewing machine produces unusual vibration around the motor coupling area.
2. The part should also be checked if the machine develops abnormal noise during startup or operation.
3. Visible cracks, deformation, hardening, compression or missing rubber sections indicate that the coupling ring may no longer provide reliable buffering.
4. Unstable rotation or excessive movement between the motor and upper shaft coupling can also indicate coupling component wear.
5. The complete coupling assembly should be inspected before replacement to confirm whether the rubber ring or other connected parts are damaged.

• Is this coupling rubber ring suitable for every Juki DU-1481 machine

  Different machine versions may use different parts. Please send the complete model and old part photos so that compatibility can be checked before ordering.

• What is the function of this rubber ring

  It is installed between the motor coupling and upper shaft coupling. It helps transmit rotary motion and provides flexible buffering between the coupling components.

• Can I replace only the rubber ring

  The rubber ring can normally be replaced separately when the metal coupling components remain in usable condition. The complete coupling assembly should be inspected before installation.

• Can you supply the upper shaft coupling and motor coupling

  Please send the required part numbers or photos. We can check the related coupling components together.

• Can you supply other industrial sewing machine parts and cutter parts

  Yes. We supply a wide range of garment machinery parts, industrial sewing machine parts and automatic cutter parts for factories, maintenance companies and distributors.

• What information is required for an order

  Please provide the machine model, original part number, clear product photos, required quantity and delivery address.
