Product Description

The RULAND MANUFACTURING Jaw Coupling Hub is a zero-backlash curved jaw coupling hub in the MJS57 coupling size, with a 57.2 mm outside diameter. This metric, aluminum hub (MPN MJSC57-19-A) is designed for motion control applications requiring precise torque transmission without backlash.

Frequently Asked Questions

What is a RULAND MANUFACTURING MJS57 jaw coupling hub used for?

A RULAND MANUFACTURING MJS57 zero-backlash curved jaw coupling hub connects two shafts in motion-control systems, compensating for minor misalignment while transmitting torque. It is commonly used in servo motors, encoders, and precision industrial machinery where accurate positioning and vibration damping are required.

What are the specifications of the RULAND MANUFACTURING MJSC57-19-A coupling hub?

The RULAND MANUFACTURING MJSC57-19-A is a metric, aluminum zero-backlash curved jaw coupling hub. It has a 57.2 mm outside diameter and is part of the MJS57 coupling size. This hub is designed for use with matching spider inserts to form a complete jaw coupling assembly.

Where to buy RULAND MANUFACTURING MJSC57-19-A coupling hubs worldwide?

You can source RULAND MANUFACTURING MJSC57-19-A coupling hubs worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this metric aluminum hub.

How to select the correct RULAND MANUFACTURING jaw coupling hub for an application?

To select the correct RULAND MANUFACTURING jaw coupling hub, match the hub bore size to your shaft diameter and confirm the outside diameter (57.2 mm for MJS57) fits your space. Consider torque requirements and misalignment tolerance. The aluminum MJSC57-19-A is suitable for lighter-duty, corrosion-resistant applications.
