Frequently Asked Questions

What is a Ruland Manufacturing balanced shaft collar used for?

A Ruland Manufacturing balanced shaft collar secures components on rotating shafts in high-speed applications such as spindles and precision machinery. The 2-piece clamp-on design prevents marring the shaft, and the 303 stainless steel construction resists corrosion in demanding industrial environments.

What are the specifications of the Ruland SPB-31-SS balanced shaft collar?

The Ruland SPB-31-SS is a 2-piece, inch, round, clamp-on balanced shaft collar with a 1 15/16 in bore diameter. It is made from 303 stainless steel and is designed for high-speed balancing to minimize vibration. The manufacturer part number is SPB-31-SS.

Where to buy Ruland Manufacturing shaft collars worldwide?

How to install a 2-piece clamp-on shaft collar?

To install a 2-piece clamp-on shaft collar like the Ruland SPB-31-SS, first clean the shaft surface. Place the collar halves around the shaft, align the bore, then tighten the screws evenly in a star pattern to the manufacturer’s recommended torque. This ensures secure clamping without shaft damage.
