1-3/8 in Steel Shaft Collar

The Ruland Manufacturing CL-22-F is a one-piece clamp-style shaft collar with a 1-3/8 in round bore. It is intended for technicians and machine builders who need to position or secure components on inch-sized shafts in power transmission assemblies.

Inch-Series Clamping Limits

The collar uses a single alloy steel screw to clamp directly onto a round shaft without a keyway. Its 2 1/4 in outside diameter and 2.47 in clearance diameter define the space required for installation and tool access. The 9/16 in width fixes the axial grip length available on the shaft.

Carbon Steel Build and Black Oxide Finish

The body is made from 1215 lead-free carbon steel with a black oxide coating for corrosion resistance. The one-piece construction eliminates the split-line misalignment seen on two-piece collars, while the alloy steel screw provides the clamping force needed for everyday torque loads.

Questions about this item

Which bore size should I choose for a 1-3/8 in shaft?

The collar is offered in a single 1-3/8 in bore diameter, matching that shaft size directly.

How much radial space does the 2.47 in clearance diameter need?

The 2.47 in clearance diameter sets the minimum pocket or housing bore required for the collar to rotate freely.

What does the 1215 steel grade mean for clamping force?

Grade 1215 lead-free carbon steel with black oxide finish provides consistent screw torque and holding power on the shaft.
