229-15359 Driving Shaft Crank for Juki DDL Machines

The 229-15359 Driving Shaft Crank Assembly is designed for industrial single-needle lockstitch machines that require stable rotary power transmission through the main drive mechanism. Its precision-machined shaft bore and forged-steel construction support reliable mechanical movement during continuous garment production.

Key Features

• Precision Rotary Drive Transmission: Transfers rotational movement through the main drive mechanism for consistent machine operation.
• Heavy-Duty Forged Steel Construction: Built to withstand repeated torsional and mechanical loads in industrial sewing.
• Precision-Machined Shaft Bore: Accurate internal machining helps maintain secure shaft engagement and controlled rotation.
• Secure Set-Screw Mounting: Threaded locking points provide firm attachment to the driving shaft.
• Stable High-Speed Operation: Balanced construction helps reduce unwanted movement and mechanical vibration.
• Direct Replacement Design: Suitable for replacing a worn or damaged crank with the corresponding 229-15359 specification.
• Pack of 1: Supplied as one driving shaft crank assembly.

Use Cases

The 229-15359 crank is used within the main drive and feed-drive mechanism of compatible industrial single-needle lockstitch sewing machines.

It is suitable for:

• Garment factories
• Tailoring workshops
• Production sewing lines
• Uniform manufacturing
• Shirt manufacturing
• Woven garment production
• Denim sewing
• Light and medium-weight apparel production
• Heavy-duty industrial sewing applications

The crank works as part of the machine’s mechanical drive system, where accurate rotary movement is essential for coordinated sewing-machine operation.

Benefits

Reliable Drive Transmission

The crank transfers rotational movement through the machine’s drive mechanism, supporting coordinated movement of connected components during sewing.

Strong Mechanical Construction

Forged alloy-steel construction provides resistance to bending, twisting, and repeated mechanical loading encountered during industrial operation.

Secure Shaft Connection

The locking screw arrangement helps secure the crank to the driving shaft and prevents unwanted movement at the connection point.

Reduced Mechanical Play

Precision-machined internal surfaces help maintain a controlled fit between the crank and shaft, reducing excessive movement caused by worn or poorly fitted components.

Suitable for Production Use

The component is designed for industrial lockstitch machines operating regularly in garment-production and professional sewing environments.

Machine Compatibility

This driving shaft crank is specified for compatible Juki DDL-series single-needle lockstitch machines:

Part Numbers: 229-15359 / 22915359 / 229-15367

Specifications

How To Use

First, switch off and unplug the sewing machine before accessing the main shaft or drive mechanism.

Next, remove the required machine covers and identify the existing crank and its position on the driving shaft. Inspect the shaft, locking screws, and adjoining drive components for wear.

Then, remove the worn crank and install the 229-15359 replacement in the same position, ensuring the shaft is correctly seated and the locking screws are securely tightened.

Finally, rotate the machine manually through a complete cycle to check for smooth movement and proper clearance, then run the machine at low speed before returning it to normal production.

FAQs

What is a driving shaft crank used for in a lockstitch machine?

The driving shaft crank is part of the machine’s mechanical drive system. It transfers rotational movement from the main shaft to connected mechanisms that must move in coordination during sewing. Correct crank positioning and secure shaft attachment are important for maintaining proper mechanical timing.

Is 229-15359 compatible with Juki DDL-8700?

Yes. The supplied compatibility specification lists the Juki DDL-8700 and DDL-8700-7 among the compatible machines. Before ordering, compare the existing crank’s part number and physical mounting configuration with the replacement.

What is the difference between 229-15359 and 229-15367?

The supplied product information identifies 229-15359 and 229-15367 as related part-number references for this crank. Because industrial sewing machines can have different subclasses and revisions, confirm the exact number used by your machine before ordering.

What are the signs of a worn driving shaft crank?

Common signs include excessive mechanical play, abnormal movement around the shaft connection, visible wear at the mounting area, unusual vibration, or noise from the drive mechanism.

Can a worn crank affect stitch quality?

Yes. Excessive play in the drive mechanism can affect the coordinated movement of connected machine components. This may contribute to inconsistent machine timing or operation.

Is this crank suitable for industrial sewing?

Yes.  Correct installation, shaft alignment, lubrication, and machine timing are essential for dependable operation.

Can I use this crank on another brand of lockstitch machine?

 Jack, Singer, Brother, Typical, Zoje, and SunStar machines can have different drive configurations even within the same general machine type.

How should the crank be installed?

The replacement crank should be positioned on the driving shaft in the same orientation and location as the original component, with its locking screws properly engaging the shaft.
