Frequently Asked Questions

What is a Ruland Manufacturing balanced shaft collar used for?

A Ruland Manufacturing balanced shaft collar secures components on a rotating shaft without marring the surface. Its 2-piece clamp-on design and 1215 steel construction provide high concentricity and balance, making it ideal for precision motion control, packaging, and automation equipment where vibration must be minimized.

What are the specifications of the Ruland SPB-21-F balanced shaft collar?

The Ruland SPB-21-F is a 2-piece, inch, round, clamp-on balanced shaft collar with a 1 5/16 in bore diameter. It is made from 1215 steel and is designed for applications requiring reduced vibration and precise positioning. The manufacturer part number is SPB-21-F.

Where to buy a Ruland Manufacturing balanced shaft collar worldwide?

3G Electric supplies and delivers Ruland Manufacturing balanced shaft collars worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure your order arrives at your facility. Contact us for availability and lead time on the SPB-21-F or other Ruland components.

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

To install a 2-piece clamp-on shaft collar like the Ruland SPB-21-F, first clean the shaft and collar bore. Place the collar halves around the shaft, align the screws, and tighten them evenly in a star pattern to the manufacturer's recommended torque. This ensures a secure, balanced grip without damaging the shaft.
