Shaft Collar 1-1/8 Inch Bore
This one-piece clamp-style shaft collar fits a round bore of 1-1/8 inches. It is machined from 303 stainless steel for corrosion resistance and includes a matching stainless steel screw. The collar suits power transmission assemblies where a secure axial stop or component mount is required.
Compatibility Check Before Ordering
Verify that the shaft diameter matches the 1-1/8 inch bore exactly, as the clamp relies on a precise interference fit. Confirm the 1 7/8 inch outside diameter and 2.14 inch clearance diameter clear adjacent parts in your assembly. Ensure the 1/2 inch collar width fits the available axial space on the shaft.
Thermals Noise and Power Draw
As a passive mechanical fastener the collar generates no heat, produces no noise and draws no electrical power during operation. Stainless steel construction maintains clamping force across a wide temperature range without degradation. The 303 grade material resists galling on the screw threads for reliable repeated adjustment.

Questions about this item
What comes in the box with the CL-18-SS shaft collar and do I need to buy the clamp screw separately?
The package contains one 1-piece clamp-style collar with its stainless steel screw already fitted; no additional hardware is required for installation.
How do I decide between the 1-1/8 in bore and other sizes in the CL series?
Choose the CL-18-SS when the shaft measures exactly 1-1/8 in; the collar’s bore is machined to that diameter so a different size would not fit the same shaft.
What does the 2.14 in clearance diameter mean once the collar is mounted on a shaft?
It is the outer envelope the collar sweeps when clamped — keep adjacent components at least 2.14 in from the shaft centreline to avoid interference.
