Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING MJC70 jaw coupling hub used for?

The RULAND MANUFACTURING MJC70 is a zero-backlash curved jaw coupling hub used in motion control applications that require precise torque transmission without backlash. It is commonly found in servo motors, encoders, and linear actuators where accurate positioning and vibration damping are critical.

What are the specifications of the RULAND MANUFACTURING MJC70 coupling hub?

The RULAND MANUFACTURING MJC70 coupling hub has a 69.9 mm outside diameter, is made of aluminum, and uses a metric configuration. It is designed for the MJC70 coupling size and is identified by manufacturer part number MJCC70-25-A. This hub is intended for zero-backlash curved jaw couplings.

Where to buy RULAND MANUFACTURING MJC70 coupling hubs worldwide?

You can source the RULAND MANUFACTURING MJC70 coupling hub through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this and other motion control 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., MJC70) to your shaft diameters and torque requirements. Ensure the outside diameter (69.9 mm for MJC70) fits your application space. Always verify bore size and keyway dimensions against your motor and driven shaft specs.

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.
