Frequently Asked Questions

What is the RULAND MANUFACTURING MJC80 jaw coupling hub used for?

The RULAND MANUFACTURING MJC80 is a zero-backlash curved jaw coupling hub used to connect two shafts in motion-control systems, such as servo motors and encoders. It accommodates misalignment while transmitting torque smoothly. Common in packaging, robotics, and machine-tool applications, it is made of aluminum for lightweight, corrosion-resistant performance.

What are the specifications of the RULAND MANUFACTURING MJCC80-45-A?

The RULAND MANUFACTURING MJCC80-45-A is a metric, aluminum jaw coupling hub with a 79.4 mm outside diameter. It is part of the MJC80 coupling size series and is designed for zero-backlash curved jaw couplings. The manufacturer part number is MJCC80-45-A, and it is suitable for precision motion-control applications.

Where to buy the RULAND MANUFACTURING MJC80 coupling hub worldwide?

How to select the correct RULAND MANUFACTURING jaw coupling hub?

To select the correct RULAND MANUFACTURING jaw coupling hub, match the coupling size (e.g., MJC80) to your shaft diameters and torque requirements. Verify the outside diameter (79.4 mm for the MJCC80-45-A) and material (aluminum for low inertia). Ensure the hub type (curved jaw, zero-backlash) fits your application's misalignment and precision needs.
