Product Description

Frequently Asked Questions

What is the RULAND MANUFACTURING PCR12-4-4-A motion control coupling used for?

The RULAND MANUFACTURING PCR12-4-4-A is a high-precision clamp-on beam shaft coupling used to connect two shafts while accommodating up to 3° angular misalignment. It is ideal for motion control applications in automation, packaging, and robotics where accurate torque transmission and zero backlash are required.

What are the specifications of the RULAND MANUFACTURING PCR12-4-4-A coupling?

The PCR12-4-4-A is a round, inch-sized coupling with a 1/4 in bore diameter and same bore dimensions. It accommodates 3° angular misalignment, has no keyway, and is manufactured by RULAND MANUFACTURING. The part number is PCR12-4-4-A.

Where to buy the RULAND MANUFACTURING PCR12-4-4-A coupling worldwide?

3G Electric supplies the RULAND MANUFACTURING PCR12-4-4-A coupling to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this high-precision clamp-on beam shaft coupling.

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

To install the PCR12-4-4-A, align the shafts within 3° angular misalignment, slide the coupling over both shaft ends, and tighten the clamp screws evenly to the manufacturer’s recommended torque. Ensure bores are clean and free of debris for proper grip and zero backlash performance.
