Frequently Asked Questions

What is a RULAND MANUFACTURING MJCC51-25-A jaw coupling hub used for?

The RULAND MANUFACTURING MJCC51-25-A is a zero-backlash curved jaw coupling hub used to connect two shafts in motion-control systems, compensating for minor misalignment. It is commonly applied in servo motors, encoders, and precision industrial machinery where accurate torque transmission and vibration damping are required.

What are the specifications of the RULAND MANUFACTURING MJCC51-25-A coupling hub?

The MJCC51-25-A is a jaw coupling hub with a 50.8 mm outside diameter, sized for MJC51 couplings. It is made of aluminum and has a metric bore. The manufacturer part number is MJCC51-25-A, and it is produced by RULAND MANUFACTURING. This hub is designed for zero-backlash curved jaw coupling systems.

Where to buy RULAND MANUFACTURING MJCC51-25-A coupling hubs worldwide?

You can source the RULAND MANUFACTURING MJCC51-25-A coupling hub through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this component as part of our extensive product range.

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 ensure the outside diameter (50.8 mm for MJC51) fits the coupling spider. Consider torque requirements, misalignment tolerance, and operating temperature. Aluminum hubs suit lighter loads; consult the manufacturer's catalog for exact ratings.

Used in

Common applications for RULAND MANUFACTURING

Automated packaging machinery — Ruland beam couplings (e.g., PSR20-8-5-A) for connecting servo motors to conveyor drive shafts.

CNC machine tools — Ruland rigid couplings (e.g., CLX-4-4-A) for precise alignment of ball screw assemblies.
