Frequently Asked Questions

What is a RULAND MANUFACTURING Balanced Shaft Collar used for?

A RULAND MANUFACTURING Balanced Shaft Collar is used to secure components on a shaft in high-speed rotating applications, such as spindles or precision machinery. The 2-piece clamp-on design provides balanced clamping force to minimize vibration, making it ideal for applications requiring smooth operation at elevated RPM.

What are the specifications of the RULAND MANUFACTURING MSPB-21-SS shaft collar?

The RULAND MANUFACTURING MSPB-21-SS is a 2-piece, metric, round, clamp-on balanced shaft collar with a 21 mm bore diameter. It is made from 303 stainless steel, offering corrosion resistance and durability. The manufacturer part number is MSPB-21-SS, and it is designed for precision shaft mounting in industrial equipment.

Where to buy RULAND MANUFACTURING shaft collars worldwide?

You can source RULAND MANUFACTURING shaft collars worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the MSPB-21-SS 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 MSPB-21-SS, first clean the shaft and collar bore. Place the collar halves around the shaft, align the screws, and tighten them evenly in a cross pattern to the manufacturer's recommended torque. This ensures balanced clamping and prevents shaft damage.
