RULAND MANUFACTURING Jaw Coupling Hub: MJS57 Coupling Size, 57.2 mm Outside Dia, Metric

A Ruland Manufacturing zero-backlash curved jaw coupling hub connects two shafts in motion-control systems, compensating for minor misalignment while transmitting torque. It is commonly used in servo motors, encoders, and precision positioning equipment across industrial automation, packaging, and machine tool applications.

The Ruland Manufacturing MJSC57-30-A is a metric aluminum zero-backlash curved jaw coupling hub with a 57.2 mm outside diameter. It is designed for use with Ruland MJS coupling size spiders and is suitable for applications requiring precise torque transmission and misalignment accommodation.

3G Electric supplies Ruland Manufacturing jaw coupling hubs worldwide, handling full logistics and customs clearance for international orders. As a global industrial solutions provider, we source genuine Ruland components like the MJSC57-30-A and deliver them to your facility, regardless of location.

To select the correct Ruland Manufacturing jaw coupling hub, match the outside diameter and bore size to your shaft dimensions, and confirm the coupling size (e.g., MJS57) matches the spider. Consider torque requirements, misalignment tolerance, and material—aluminum hubs like the MJSC57-30-A suit lighter loads, while steel handles higher torque.
