Unique-Bargains 8mm to 8mm Shaft Coupling Flexible Coupler Motor Connector Joint L25xD19 Silver

Precision 8 mm shaft coupler

This one-piece aluminium-alloy coupling joins two 8 mm shafts with zero backlash. Its metallic spring design absorbs parallel, angular and end-play misalignments while transmitting light to medium torque. The 25 mm overall length and 19 mm outside diameter suit compact encoder, leadscrew or small-pump drives. Set screws lock each shaft securely in place.

Replaces rigid or worn couplings

A solid coupling cannot tolerate misalignment and will bind or damage bearings. This flexible spring unit upgrades those joints when shafts are slightly offset or subject to vibration. The jump is worth it whenever backlash must be eliminated and some torsional compliance is needed. It is not for buyers who need high-torque power transmission or large-diameter shaft connections.

Verify shaft size and torque needs

Confirm both shafts are exactly 8 mm in diameter before ordering. Check that the 25 mm length and 19 mm body diameter fit within the available space between components. Ensure the application torque falls within the light-to-medium range this spring coupling is designed for. Heavier loads or larger shafts require a different coupling style.
