FAQs
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?
No. The 17220007 rubber ring is listed separately for Jack F4, F5 and F6 at ₹50. This product is the coupling in 14 mm and 14.7 mm sizes at ₹400 to ₹449, checked on 5 October 2026. Compare the shape with your old part before buying.
Can I pay cash on delivery?
Yes. StitchPartner delivers pan-India with COD available on this coupling. If you are also replacing the motor, see the universal direct-drive servo motor and the flywheel coupling assembly. Browse more parts in Jack F4 F5 F6 spare parts and DDL-8100/8300/8500/8700 spare parts.
