Frequently Asked Questions

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

A Ruland zero-backlash curved jaw coupling hub connects two shafts while compensating for minor misalignment. It is used in motion control, packaging, and automation equipment where precise torque transmission and damping of vibration are critical. The aluminum construction keeps inertia low for high-speed applications.

What are the specifications of the Ruland MJSC51-16-A coupling hub?

The Ruland MJSC51-16-A is a metric aluminum jaw coupling hub with a 50.8 mm outside diameter and MJS51 coupling size. It is designed for zero-backlash curved jaw coupling systems. The part number is MJSC51-16-A, and it is manufactured by Ruland Manufacturing.

Where to buy Ruland MJSC51-16-A coupling hubs worldwide?

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.
