Flexible Shaft Coupling Connector

Description

Flexible Shaft Coupling Connector – 5mm/6.35mm to 8mm Thread Bore for NEMA 17/23 & Lead Screw

Connect your motor to a lead screw with this Flexible Shaft Coupling Connector. Designed to link NEMA 17 or NEMA 23 stepper motors to 8mm lead screws, this coupling removes lead screw clearance and improves print quality.

The Flexible Shaft Coupling Connector features a 5mm or 6.35mm bore on one end and an 8mm x 1.25mm threaded bore on the other. This direct-thread design eliminates the periodic rough texture caused by M8 clearance in 3D printing.

Made from aluminum with a flexible coupling structure, this Flexible Shaft Coupling Connector has a 20mm outside diameter and 25mm length. It simplifies debugging and keeps motion smooth and precise for 3D printers, CNC machines, and DIY builds.
