D25L35 Rigid Shaft Coupler  - 8mm * 10mm

Overview

D25L35 Rigid Shaft Coupler

The D25L35 Rigid Shaft Coupler is a precision-machined aluminum coupling designed for securely connecting two shafts with minimal backlash and maximum torque transmission. Unlike flexible couplers, this rigid coupling provides a solid mechanical connection, making it ideal for applications where accurate shaft alignment and precise motion transfer are required.

With a 25mm outer diameter and 35mm length, the D25L35 rigid coupler is commonly used in CNC machines, 3D printers, lead screw drives, robotics, and automation systems. Its multi-screw clamping design ensures a firm grip on both shafts for reliable long-term operation.

This product is available as a variable product in the following shaft size combinations:

• 8mm × 10mm

• 6mm × 8mm

Select the required variant to match your motor shaft and driven shaft sizes.
