Precision 1-7/16 in Bore Collar

The Ruland CL-23-F is a one-piece clamp-style shaft collar with a 1-7/16 inch round bore machined from carbon steel grade 1215. It suits maintenance crews and machine builders who need a secure, axial locking component for inch-series shafts in power transmission assemblies.

Clamp Force and Clearance Limits

The single-piece design relies on a single alloy steel screw to generate holding power through friction on the shaft surface. A clearance diameter of 2.47 inches defines the radial space required, so adjacent components must stay outside this envelope to avoid interference during installation or adjustment.

Carbon Steel Build and Daily Use

Grade 1215 carbon steel provides consistent machinability and strength for general industrial environments. The 9/16 inch collar width and 2 1/4 inch outside diameter create a compact profile, while the alloy steel screw resists stripping during repeated tightening cycles on round shafts without keyways.

Questions about this item

Which bore size should I select for a 1-7/16 inch shaft?

Choose the CL-23-F model with a 1-7/16 inch bore diameter to match your shaft exactly.

What does the 2.47 inch clearance diameter mean when the collar is installed?

The 2.47 inch clearance diameter is the space the collar occupies around the shaft, so adjacent components must stay outside that circle.

How does the alloy steel screw work with the carbon steel collar in a clamping application?

The alloy steel screw threads into the 1215 carbon steel collar body, providing strong holding force without damaging the shaft surface.
