209552-92 Upper Looper Drive Crank for Pegasus M700

The 209552-92 Upper Looper Drive Crank Linkage is designed for industrial overlock and safety-stitch machines that require precise, stable motion in the drive mechanism. Its forged high-tensile alloy-steel construction and precision-machined connection points make it suitable for continuous production use in garment factories, tailor shops, and industrial sewing operations.

Key Features

• High-Precision Reciprocating Drive: Converts rotary machine motion into controlled reciprocating movement for consistent overlock mechanism operation.
• Forged High-Tensile Alloy Steel: Built to withstand mechanical load, repeated movement, friction, and demanding industrial sewing cycles.
• Precision-Machined Journals: Accurately finished connection areas help reduce unwanted play and vibration during high-speed operation.
• Optimized Lubrication: Lubrication-friendly design supports smooth movement around the working pivot points.
• Direct Replacement Design: Made to the specified original-part dimensions for straightforward replacement during machine servicing.
• Industrial-Duty Construction: Suitable for continuous operation on high-speed overlock and safety-stitch machines.
• Pack of 1: Supplied as one crank component for replacement or machine repair.

Use Cases

 It is suitable for production environments handling:

• Knitted garments
• Woven fabrics
• Denim
• Fleece
• Activewear
• Light-to-heavy garment materials
• High-volume overedging and seaming operations

For maintenance technicians, machine mechanics, and garment-production workshops, replacing a worn crank helps restore the correct mechanical movement between connected drive components.

Benefits

Consistent Mechanical Movement
The precision-machined crank provides controlled movement within the machine’s drive mechanism, helping connected components operate in synchronization.

Reduced Mechanical Play
Accurately finished connection points help maintain the intended relationship between moving components and reduce unwanted movement caused by worn linkage parts.

Supports Reliable Stitch Formation
Correct drive-mechanism movement is essential for maintaining the timing and coordination of the machine’s sewing components.

How To Use

First, switch off and disconnect the sewing machine from its power source before beginning any mechanical servicing.

Next, remove the required machine covers and inspect the existing crank, connected linkage, pins, and fastening points for wear or damage.

Finally, lubricate the relevant moving points according to the machine’s maintenance procedure, rotate the machine manually to check for smooth movement, and run the machine at low speed before returning it to normal production speed.

FAQs

Is the 209552-92 crank compatible with Pegasus M732 machines?

Yes. The 209552-92 crank is listed in the Pegasus M732 parts documentation as the crank used in the needle-drive mechanism. The parts listing identifies 209552-92 as item 3 with a quantity of one.

Can this crank be used on Pegasus M752 machines?

Yes. The Pegasus M700-series parts documentation includes 209552-92 in the needle-drive mechanism and covers M752 configurations.

What does the 209552-92 crank do in an overlock machine?

The crank transfers rotational movement from the machine’s drive system into the required reciprocating movement of the connected mechanism.

Is this crank suitable for high-speed industrial sewing?

Yes. Proper lubrication, correct installation, and correct machine timing remain important for reliable high-speed operation.
