Product Description

Frequently Asked Questions

What is a RULAND MANUFACTURING Jaw Coupling Hub used for?

This zero-backlash curved jaw coupling hub connects two shafts in motion-control applications, transmitting torque while accommodating minor misalignment. It is commonly used in packaging, printing, and robotics equipment where precise, backlash-free power transmission is critical.

What are the specifications of the RULAND MANUFACTURING JC44-16-A hub?

The RULAND MANUFACTURING JC44-16-A is a JC44 coupling size hub with a 2 3/4 in outside diameter. It is made of aluminum and designed for inch-sized shafts. This zero-backlash curved jaw hub is compatible with RULAND MANUFACTURING jaw couplings for reliable motion control.

Where to buy RULAND MANUFACTURING jaw coupling hubs worldwide?

3G Electric supplies RULAND MANUFACTURING jaw coupling hubs worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on the JC44-16-A or other coupling sizes.

How to select the right RULAND MANUFACTURING jaw coupling hub?

Select the hub based on shaft diameter, torque requirements, and coupling size. The JC44-16-A fits JC44 couplings with a 2 3/4 in outside diameter. Ensure the hub bore matches your shaft size and that the material (aluminum here) suits your environment. Consult RULAND MANUFACTURING's catalog for load ratings.

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.
