Product Description

Frequently Asked Questions

What is a Ruland Manufacturing zero-backlash curved jaw coupling hub used for?

A Ruland Manufacturing zero-backlash curved jaw coupling hub connects two rotating shafts while compensating for minor misalignment. It is commonly used in motion control, packaging, and automation equipment where precise torque transmission and damping of vibration are required.

What are the specifications of the Ruland Manufacturing JS36 coupling hub?

The Ruland Manufacturing JS36 coupling hub has a 2 1/4 in outside diameter and is made of aluminum. It is an inch-series, zero-backlash curved jaw coupling hub with manufacturer part number JSC36-12-A. It is designed for use with Ruland jaw couplings in motion control applications.

Where to buy Ruland Manufacturing coupling hubs worldwide?

You can source Ruland Manufacturing coupling hubs worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the JSC36-12-A or other Ruland components.

How to select the correct Ruland Manufacturing jaw coupling hub size?

To select the correct Ruland Manufacturing jaw coupling hub, match the coupling size (e.g., JS36) to your shaft diameters and torque requirements. Verify the outside diameter (2 1/4 in for this model) and ensure the hub material (aluminum) suits your environment. Consult Ruland's technical data for bore and keyway options.

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.
