Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING PCMR25-8-6-SS coupling used for?

The RULAND MANUFACTURING PCMR25-8-6-SS is a high-precision clamp-on beam shaft coupling used in motion control applications. It connects two shafts while accommodating up to 3° angular misalignment, making it ideal for servo motors, encoders, and linear actuators in automation and robotics systems.

What are the specifications of the RULAND MANUFACTURING PCMR25-8-6-SS?

The PCMR25-8-6-SS is a round, metric coupling with an 8 mm bore diameter 1 and different bore dimensions. It features a clamp-on design, accommodates 3° angular misalignment, and is manufactured by RULAND MANUFACTURING. The part number is PCMR25-8-6-SS.

Where to buy the RULAND MANUFACTURING PCMR25-8-6-SS worldwide?

3G Electric supplies the RULAND MANUFACTURING PCMR25-8-6-SS coupling worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us to source this high-precision motion control coupling for your application.

How to install a RULAND MANUFACTURING clamp-on beam coupling?

To install the PCMR25-8-6-SS, clean both shaft ends and slide the coupling over them. Tighten the clamp screws evenly to the manufacturer's recommended torque using a hex key. Ensure the shafts are aligned within the 3° angular misalignment limit. Avoid over-tightening to prevent damage.
