It is used in precision motion control, robotics, and automation applications where high-speed rotation demands minimal vibration. The 2-piece clamp-on design provides secure, balanced holding force.

What are the specifications of the Ruland SPB-5-A balanced shaft collar?

The Ruland SPB-5-A is an inch-series, 2-piece round clamp-on shaft collar with a 5/16 in bore diameter. It is made from 2024 aluminum for lightweight, corrosion-resistant performance. The balanced design reduces vibration in high-speed applications.
