Rubber Coupling for Single Needle Lock-Stitch Machine

This rubber coupling for single needle lock-stitch machines connects the motor drive to the main shaft on direct-drive setups and cushions the shock between the two. Best for workshops and garment units fixing a worn, cracked or slipping coupling on a Jack F4/F5/F6, DDL-8700 type or similar machine. It comes in 14 mm and 14.7 mm sizes.

When to Replace the Coupling

• The rubber is cracked, chipped or has hardened.
• The machine knocks when the motor starts or stops.
• The motor runs but the needle lags behind it.
• You are changing the servo motor and want a fresh coupling on the new setup.

पूछे जाने वाले प्रश्न

Which size do I need, 14 mm or 14.7 mm?

Compare your old coupling with the size shown in the options before ordering. The two sizes differ by only 0.7 mm, but a wrong pick can fit loosely and slip. If you cannot tell, check your old part against the product photos first.

Which machines is this coupling for?

It is listed for the Jack F4, F5 and F6, the DDL-8100 to DDL-8700 groups, the 9100 group, and the Brother DA-9270 / 9280 and Jack JK-T9270 / T9280. The sources we checked describe it for direct-drive single needle machines, so confirm the fit on your own machine.

How do I know the rubber coupling is worn?

Look for cracks, chipped lobes or a hardened surface, and listen for a knock when the motor starts or stops. A motor that spins while the needle lags is another usual sign. Rubber is a wear part, so an early swap is cheaper than repairing shaft damage later.

Is this the same as the 17220007 rubber ring?
