Shaft Collar for 1 in Bore

The Ruland CL-16-A is a one-piece clamp collar machined from 2024 aluminum alloy. It fits a 1 in round bore and uses an alloy-steel screw to lock onto a shaft without marring the surface. This component suits maintenance crews and OEM assemblers who need quick, repeatable positioning on inch-series equipment.

Replaces Set-Screw Collars

A clamp collar distributes holding force around the full circumference, eliminating the point-loading that damages shafts and loosens under vibration. The jump is worth it when the application sees reversing loads, frequent adjustment cycles or when the shaft material is softer than the screw. It also removes the need to drill a dimple or flat for a set screw.

Fits 1 3/4 in OD Envelope

The 1/2 in width and 2.03 in clearance diameter define the space the collar occupies on the shaft and the sweep radius for adjacent parts. The aluminum body saves weight over steel equivalents while the alloy-steel screw maintains clamping torque. Buyers who need a two-piece split design for mid-shaft installation or a stainless-steel screw for corrosive environments cannot use this version.

Questions about this item

What shaft diameter does the 1 in bore fit?

The collar has a round bore of 1 in diameter, so it clamps directly onto a 1 in shaft without a keyway.

How do you install the single-piece clamp collar correctly?

Slide the collar onto the shaft, then tighten the alloy-steel screw until the split closes evenly; over-tightening can distort the 2024 aluminium body.

When should the collar be replaced?

Replace it if the bore becomes oval, the screw threads strip, or the aluminium shows cracks from repeated clamping cycles.
