Product Description

The RULAND MANUFACTURING MJCC57-30-A is a zero-backlash curved jaw coupling hub in the MJC57 coupling size, made of metric aluminum with a 57.2 mm outside diameter. This hub is designed for precision motion control applications requiring accurate torque transmission without backlash.

Frequently Asked Questions

What is a Ruland Manufacturing zero-backlash curved jaw coupling hub used for?

A Ruland Manufacturing zero-backlash curved jaw coupling hub connects two shafts in motion-control applications, compensating for minor misalignment while transmitting torque. It is commonly used in servo motors, encoders, and precision positioning systems across industrial automation, packaging, and machine tool sectors.

What are the specifications of the Ruland MJCC57-30-A jaw coupling hub?

The Ruland MJCC57-30-A is a metric aluminum jaw coupling hub with a 57.2 mm outside diameter. It is part of the MJC57 coupling size family and is designed for zero-backlash curved jaw coupling systems. The aluminum construction provides low inertia and corrosion resistance for light- to medium-duty applications.

Where to buy Ruland Manufacturing jaw coupling hubs worldwide?
