Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING PCR20-8-8-A coupling used for?

The RULAND MANUFACTURING PCR20-8-8-A is a high-precision clamp-on beam shaft coupling used in motion control applications. It accommodates 3° angular misalignment and connects two 1/2 inch shafts with the same bore dimensions, making it ideal for servo systems and linear actuators.

What are the specifications of the RULAND MANUFACTURING PCR20-8-8-A?

The PCR20-8-8-A has a 1/2 inch bore diameter, round bore shape, and same bore dimensions. It is inch-sized, has no keyway, and allows 3° angular misalignment. The manufacturer part number is PCR20-8-8-A, and it is made by RULAND MANUFACTURING.

Where to buy the RULAND MANUFACTURING PCR20-8-8-A worldwide?

3G Electric supplies the RULAND MANUFACTURING PCR20-8-8-A coupling worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver this high-precision motion control coupling to your facility, regardless of location.

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

To install the PCR20-8-8-A, align the shafts within 3° angular misalignment, slide the coupling over both shaft ends, and tighten the clamp screws evenly with a torque wrench to the manufacturer's recommended value. Ensure bores are clean and free of debris before installation.
