Product Description

The RULAND MANUFACTURING Two-Piece Rigid Shaft Coupling (SKU SPC-20-20-SS, MPN SPC-20-20-SS) is a round keyed coupling with a 1 1/4 in bore diameter for both bore 1 and bore 2. This product is a rigid shaft coupling designed for precise shaft alignment and torque transmission.

Frequently Asked Questions

What is a RULAND MANUFACTURING rigid shaft coupling used for?

A RULAND MANUFACTURING rigid shaft coupling connects two shafts in precision motion-control applications where misalignment is not expected. It is commonly used in packaging, printing, and robotics to transmit torque without backlash or compliance.

What are the specifications of the RULAND SPC-20-20-SS rigid shaft coupling?

The RULAND SPC-20-20-SS is a two-piece rigid shaft coupling with a 1 1/4 inch bore diameter on both ends. It features a round keyed design and is made by RULAND MANUFACTURING. The manufacturer part number is SPC-20-20-SS.

Where to buy RULAND rigid shaft couplings worldwide?

You can source RULAND rigid shaft couplings worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

How to select a rigid shaft coupling for a keyed shaft?

Select a rigid shaft coupling by matching the bore diameter to your shaft size and ensuring the keyway type (e.g., round keyed) aligns with your key. For the RULAND SPC-20-20-SS, both bores are 1 1/4 inch. Confirm torque and speed requirements with the manufacturer's data.
