Product Description

The RULAND MANUFACTURING Balanced Shaft Collar is a 2-piece, inch, round, clamp-on steel shaft collar with a 1 1/4 in bore diameter, made from 1215 steel (MPN SPB-20-F). It is designed for secure clamping onto shafts without marring the surface.

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. It provides precise positioning and clamping force without marring the shaft, making it ideal for CNC spindles, robotics, and other precision machinery.

What are the specifications of the Ruland SPB-20-F balanced shaft collar?

The Ruland SPB-20-F is a 2-piece, inch, round, clamp-on balanced shaft collar with a 1 1/4 in bore diameter. It is made of steel and is designed for high-speed balancing. The manufacturer part number is SPB-20-F.

Where to buy a Ruland SPB-20-F balanced shaft collar worldwide?

You can source the Ruland SPB-20-F balanced shaft collar from 3G Electric, which handles full logistics, customs clearance, and delivery to worldwide destinations. As a global industrial solutions provider, we supply genuine Ruland components for precision motion control applications.

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

To install a Ruland 2-piece clamp-on shaft collar, first clean the shaft and collar bore. Place the collar around the shaft, align the two halves, and tighten the screws evenly in a star pattern to the manufacturer's recommended torque. This ensures secure clamping without distorting the collar.
