Product Description

Frequently Asked Questions

What is a RULAND MANUFACTURING Jaw Coupling Hub used for?

A RULAND MANUFACTURING Jaw Coupling Hub, such as the JCC50-26-A, is used to connect two rotating shafts in power transmission applications. It provides zero-backlash torque transfer while accommodating minor misalignment, making it ideal for precision motion control systems, packaging machinery, and industrial automation.

What are the specifications of the RULAND MANUFACTURING JCC50-26-A?

The RULAND MANUFACTURING JCC50-26-A is a zero-backlash curved jaw coupling hub in JC50 coupling size. It has a 3 1/8 in outside diameter and is made of aluminum. This inch-series hub is designed for use with matching spider inserts to form a complete jaw coupling assembly.

Where to buy RULAND MANUFACTURING coupling hubs worldwide?

You can source RULAND MANUFACTURING coupling hubs, including the JCC50-26-A, through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive genuine components for your power transmission needs.

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., JC50) to your shaft diameters and torque requirements. Verify the outside diameter (3 1/8 in for the JCC50-26-A) and material (aluminum) suit your application. Always consult the manufacturer's catalog for bore size and keyway options.
