Product Description

Frequently Asked Questions

What is a RULAND MANUFACTURING MJC19-8-A jaw coupling hub used for?

The RULAND MANUFACTURING MJC19-8-A is a zero-backlash curved jaw coupling hub used to connect two rotating shafts while dampening vibration and accommodating minor misalignment. It is commonly applied in motion control, packaging, and automation equipment where precise torque transmission is required.

What are the specifications of the RULAND MANUFACTURING MJC19-8-A?

The MJC19-8-A is a jaw coupling hub with a 19.1 mm outside diameter, part of the MJC19 coupling size. It is made of aluminum and has a metric bore. The manufacturer part number is MJC19-8-A. This hub is designed for use with RULAND MANUFACTURING curved jaw coupling spiders.

Where to buy RULAND MANUFACTURING MJC19-8-A 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.
