Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING PCR18-8-8-A coupling used for?

The RULAND MANUFACTURING PCR18-8-8-A is a high-precision clamp-on beam shaft coupling used in motion control applications. It accommodates up to 3° angular misalignment, making it ideal for connecting shafts in servo motors, encoders, and linear actuators where accurate positioning and zero backlash are required.

What are the specifications of the RULAND MANUFACTURING PCR18-8-8-A coupling?

The PCR18-8-8-A is a round, inch-dimensioned coupling with a 1/2 in bore diameter and same bore dimensions. It has no keyway and is designed for 3° angular misalignment. The manufacturer part number is PCR18-8-8-A, and it is made by RULAND MANUFACTURING.

Where to buy the RULAND MANUFACTURING PCR18-8-8-A coupling worldwide?

You can source the RULAND MANUFACTURING PCR18-8-8-A coupling worldwide through 3G Electric. As a global industrial equipment distributor since 1990, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select the correct RULAND MANUFACTURING beam coupling for misalignment?

To select the correct RULAND MANUFACTURING beam coupling, first measure your shaft diameters and ensure they match the bore size (e.g., 1/2 in for the PCR18-8-8-A). Confirm the coupling's angular misalignment rating (3° for this model) exceeds your application's requirements. Choose clamp-on style for secure, keyless shaft attachment.
