Product Description

The RULAND MANUFACTURING Motion Control Coupling (MPN PCR20-4-4-SS) is a high-precision clamp-on beam shaft coupling designed for 3° angular misalignment. It features a round bore with same bore dimensions, a 1/4 in bore diameter, and is sized in inches. This coupling does not include a keyway.

Frequently Asked Questions

What is a RULAND MANUFACTURING PCR20-4-4-SS motion control coupling used for?

The RULAND MANUFACTURING PCR20-4-4-SS is a high-precision clamp-on beam shaft coupling used to connect two shafts while accommodating up to 3° of angular misalignment. It is ideal for motion control, robotics, and precision positioning applications where zero backlash and accurate torque transmission are required.

What are the specifications of the RULAND MANUFACTURING PCR20-4-4-SS coupling?

The PCR20-4-4-SS has a 1/4 in bore diameter with same bore dimensions, a round bore, and no keyway. It is sized in inches and designed for 3° angular misalignment. The coupling is made by RULAND MANUFACTURING and is a clamp-on beam type for high-precision motion control.

Where to buy a RULAND MANUFACTURING PCR20-4-4-SS coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING PCR20-4-4-SS coupling to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we source and deliver genuine RULAND MANUFACTURING motion control couplings for precision applications.

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

To install the PCR20-4-4-SS, clean both shaft ends and the bore. Loosen the clamp screws, slide the coupling onto the shafts, align the shafts within 3° angular misalignment, and tighten the screws evenly to the manufacturer’s recommended torque. Avoid over-tightening to prevent damage.
