Product Description

Frequently Asked Questions

What is a RULAND MANUFACTURING MJC25-6-A jaw coupling hub used for?

The RULAND MANUFACTURING MJC25-6-A is a zero-backlash curved jaw coupling hub used to connect two rotating shafts in motion-control applications. It accommodates misalignment and dampens vibration in servo motors, encoders, and industrial automation equipment. The aluminum construction provides low inertia for high-speed precision systems.

What are the specifications of the RULAND MANUFACTURING MJC25-6-A coupling hub?

The MJC25-6-A is a metric, aluminum jaw coupling hub with a 25.4 mm outside diameter. It is part of the MJC25 coupling size series from RULAND MANUFACTURING. This hub is designed for zero-backlash curved jaw couplings, ensuring accurate torque transmission in precision motion-control systems.
