SKU CH-BDK3-8DR8Z

A 303 stainless-steel clamp-style shaft collar with a 13/16 in bore and 1 5/8 in outside diameter

  • TypeCouplings, Collars & Adapters
  • 303 stainless steel resists corrosion in harsh environments
  • One-piece clamp design grips 13/16 in round shafts securely
  • 92 in clearance diameter clears adjacent components
  • 1/2 in collar width fits tight assemblies
  • Stainless steel screw prevents fastener corrosion

Precision Fit

The Ruland Manufacturing CL-13-SS is a one-piece clamp-type shaft collar machined from 303 stainless steel. It provides a secure, mar-free grip on a 13/16 inch round bore without the need for a keyway. The 1/2 inch width and 1 5/8 inch outside diameter suit standard shafting in motion-control assemblies.

Target Users

This collar suits engineers and maintenance teams needing corrosion-resistant clamping on inch-series shafts in food, medical, or wash-down environments. It is not for applications requiring a two-piece split design for mid-span installation, nor for bores that demand a keyway or threaded mounting holes.

Deciding Spec

The critical specification is the 13/16 inch round bore diameter, which must match the shaft exactly for the clamp to develop full holding power. A 1.92 inch clearance diameter and 1/2 inch width are fixed by the design, so verify shaft size and available radial space before ordering.

Questions about this item

Should I choose the 13/16 in bore or a different size for my shaft?

Select the 13/16 in bore only when your shaft measures exactly 13/16 in; the collar is a single-piece clamp and cannot adapt to other diameters.

What does the 1.92 in clearance diameter mean once the collar is installed?

The 1.92 in clearance diameter is the space the collar occupies radially, so adjacent components must stay outside that circle.

How does the 303 stainless steel clamp screw affect holding power?

The 303 stainless steel screw provides corrosion resistance and adequate torque for light to moderate axial loads on a 13/16 in shaft.
