Frequently Asked Questions

What is a Ruland Manufacturing jaw coupling hub used for?

A Ruland Manufacturing jaw coupling hub connects two shafts in motion-control systems, transmitting torque while accommodating minor misalignment. The curved-jaw design reduces vibration and backlash, making it ideal for servo motors, encoders, and precision industrial machinery across machining, packaging, and material handling applications.

What are the specifications of the Ruland JC16-4-A jaw coupling hub?

The Ruland JC16-4-A is a zero-backlash curved jaw coupling hub in JC16 coupling size. It has a 1 in outside diameter, is made of aluminum, and uses inch dimensions. This hub is designed for use with matching spider inserts to form a complete jaw coupling assembly.

Where to buy Ruland jaw coupling hubs worldwide?

3G Electric supplies Ruland jaw coupling hubs like the JC16-4-A to customers worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this precision coupling component.

How to select the correct Ruland jaw coupling hub size?

To select the correct Ruland jaw coupling hub, match the coupling size (e.g., JC16) to your shaft diameters and torque requirements. Verify the outside diameter and bore size fit your application. For the JC16-4-A, the 1 in outside diameter and aluminum construction suit light-to-medium duty motion control. Consult Ruland's catalog for bore and keyway options.
