Product Description

Frequently Asked Questions

What is a RULAND MANUFACTURING Jaw Coupling Hub used for?

A RULAND MANUFACTURING Jaw Coupling Hub, such as the JCC50-28-A, is used in power transmission systems to connect two shafts while accommodating misalignment. It is ideal for motion control, packaging, and conveyor applications where zero-backlash and precise torque transfer are required.

What are the specifications of the RULAND MANUFACTURING JCC50-28-A?

The RULAND MANUFACTURING JCC50-28-A is a zero-backlash curved jaw coupling hub in JC50 coupling size. It has a 3 1/8 in outside diameter, is made of aluminum, and is inch-sized. It is designed for use with RULAND MANUFACTURING curved jaw couplings.

Where to buy RULAND MANUFACTURING coupling hubs worldwide?

You can source RULAND MANUFACTURING coupling hubs, including the JCC50-28-A, through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable procurement for your operations.

How to select the right RULAND MANUFACTURING jaw coupling hub?

To select the right RULAND MANUFACTURING jaw coupling hub, match the coupling size (e.g., JC50) to your shaft diameters and torque requirements. Consider the hub's outside diameter, material (aluminum for lightweight applications), and ensure it pairs with a compatible curved jaw spider for zero-backlash performance.

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.

Robotic arm joints — Ruland Oldham coupling hubs (e.g., OSC16-6-A) for accommodating axial motion in end-effector drives.

Pump and compressor systems — Ruland stainless steel shaft collars (e.g., CL-3-ST) for securing impeller shafts.

Printing press rollers — Ruland clamp-on beam couplings (e.g., PCR18-8-8-A) for synchronizing roller rotation with minimal backlash.

Material handling conveyors — Ruland set screw couplings (e.g., PSMR29-7-7-A) for linking gearboxes to drive rollers.
