Frequently Asked Questions

What is a RULAND MANUFACTURING SP-18-A shaft collar used for?

The RULAND MANUFACTURING SP-18-A is a 2-piece, clamp-on shaft collar used to position and secure components on shafts in industrial machinery, conveyors, and automation systems. Its 2024 aluminum construction provides lightweight, corrosion-resistant performance for precision alignment and axial retention in moderate-load applications.

What are the specifications of the RULAND MANUFACTURING SP-18-A shaft collar?

The SP-18-A is an inch, round, 2-piece clamp-on shaft collar with a 1 1/8 in bore diameter. It is made from 2024 aluminum, offering strength and corrosion resistance. The manufacturer part number is SP-18-A, and it is designed for secure, non-marring clamping on shafts without damaging the surface.
