Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING FSMR25-8-8-A coupling used for?

The RULAND MANUFACTURING FSMR25-8-8-A is a general purpose set screw beam shaft coupling used in motion control applications. It accommodates up to 3° angular misalignment, making it suitable for connecting shafts in automation, packaging, and robotics equipment where precise torque transmission and alignment correction are needed.

What are the specifications of the RULAND MANUFACTURING FSMR25-8-8-A coupling?

The FSMR25-8-8-A is a round, aluminum beam coupling with metric same bore dimensions of 8 mm on both ends. It has no keyway and is designed for 3° angular misalignment. The manufacturer part number is FSMR25-8-8-A, and it is produced by RULAND MANUFACTURING.

Where to buy the RULAND MANUFACTURING FSMR25-8-8-A coupling worldwide?

You can source the RULAND MANUFACTURING FSMR25-8-8-A coupling worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this motion control coupling.

How to select the correct RULAND MANUFACTURING beam coupling for your application?

To select the correct RULAND MANUFACTURING beam coupling, match the bore diameter to your shaft size—here 8 mm on both ends. Consider the required angular misalignment (up to 3° for this model), torque needs, and whether a keyway is needed. Aluminum construction suits lighter loads; consult the manufacturer's catalog for full ratings.
