Product Description

The RULAND MANUFACTURING Two-Piece Rigid Shaft Coupling (SKU SPC-18-18-SS, MPN SPC-18-18-SS) features a 1 1/8 in bore diameter on both ends with a round keyed design. This coupling provides a direct, zero-backlash connection for shaft-to-shaft applications requiring precise 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, such as conveyors, packaging machinery, and industrial automation. It provides zero-backlash torque transmission and maintains accurate shaft alignment. The SPC-18-18-SS model is a two-piece, round keyed coupling with 1 1/8 in bore diameters.

What are the specifications of the RULAND MANUFACTURING SPC-18-18-SS rigid shaft coupling?

The RULAND MANUFACTURING SPC-18-18-SS is a two-piece rigid shaft coupling with a 1 1/8 in bore diameter on both ends. It features a round keyed design and is made of stainless steel. The manufacturer part number is SPC-18-18-SS. This coupling is designed for high-torque, low-backlash shaft connections in industrial equipment.

Where to buy RULAND MANUFACTURING rigid shaft couplings worldwide?

You can source RULAND MANUFACTURING rigid shaft couplings, including the SPC-18-18-SS, through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to worldwide destinations. Contact 3G Electric for availability and lead time on this coupling.

How to select the right RULAND MANUFACTURING rigid shaft coupling?

To select the correct RULAND MANUFACTURING rigid shaft coupling, match the bore diameters to your shaft sizes and choose the keyway type (e.g., round keyed). Consider torque requirements, shaft misalignment tolerance, and material (stainless steel for corrosion resistance). The SPC-18-18-SS is suitable for shafts with 1 1/8 in diameters. Consult 3G Electric for application guidance.
