Product Description

The RULAND MANUFACTURING MJS51-16-A is a zero-backlash curved jaw coupling hub in the MJS51 coupling size, constructed from metric aluminum with a 50.8 mm outside diameter. This component is designed for use in motion control and power transmission applications where precise torque transfer and misalignment accommodation are required.

Frequently Asked Questions

What is a RULAND MANUFACTURING MJS51-16-A jaw coupling hub used for?

The RULAND MANUFACTURING MJS51-16-A is a zero-backlash curved jaw coupling hub used to connect two shafts in motion-control systems, such as servo motors and encoders. It accommodates misalignment while transmitting torque smoothly. Common in packaging, robotics, and machine-tool applications, this aluminum metric hub pairs with a matching spider insert for reliable power transmission.

What are the specifications of the RULAND MANUFACTURING MJS51-16-A coupling hub?

The RULAND MANUFACTURING MJS51-16-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 couplings, providing precise torque transmission. The hub is part of RULAND MANUFACTURING's metric series, suitable for industrial motion-control applications requiring accurate shaft alignment.

Where to buy the RULAND MANUFACTURING MJS51-16-A coupling hub worldwide?

Contact us for availability and lead time; we source and deliver this metric aluminum hub to customers in any country.

How to select the correct RULAND MANUFACTURING jaw coupling hub for my application?

To select the correct RULAND MANUFACTURING jaw coupling hub, match the shaft diameters to the hub bore size and confirm the outside diameter (50.8 mm for MJS51) fits your space. Consider torque requirements and misalignment tolerance; curved jaw designs accommodate angular and parallel misalignment. Always verify the hub material—aluminum for low inertia—and consult RULAND MANUFACTURING's catalog for compatible spider inserts.
