Frequently Asked Questions

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

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 material handling applications.

What are the specifications of the Ruland Manufacturing MJSC51-20-A jaw coupling hub?

The Ruland Manufacturing MJSC51-20-A is a metric aluminum zero-backlash curved jaw coupling hub. It has a 50.8 mm outside diameter and is sized for the MJS51 coupling series. The aluminum construction provides low inertia and corrosion resistance, suitable for precision motion-control applications.

Where to buy a Ruland Manufacturing MJSC51-20-A jaw coupling hub worldwide?
