Ruland 1/2 Inch Stainless Shaft Collar

The Ruland SP-8-SS is a 2-piece clamp-style shaft collar made from 303 stainless steel. It fits a 1/2 inch round bore and suits machinery applications requiring secure shaft positioning. The two-piece design allows installation without removing other components from the shaft.

Two-Piece Design for Simple Mounting

The split construction lets you clamp the collar around an assembled shaft, avoiding the need to slide parts off the end. Tightening the stainless steel screws secures the 13/32 inch wide collar evenly. Ensure screws are torqued uniformly to prevent misalignment or shaft damage during operation.

Inch-Sized Clamp for Round Shafts

This collar uses the inch measurement system and accepts only round shafts of the specified diameter. It has no keyway or threaded bore, so it relies solely on clamp friction for holding power. The 1.28 inch clearance diameter defines the space needed around the shaft for the collar profile.

Questions about this item

How can I confirm the SP-8-SS collar is seated correctly on a 1/2 in shaft?

The 2-piece clamp design tightens evenly around the shaft; when the stainless steel screws are torqued to spec the collar will not rotate or slide on the 1/2 in bore.

What components are included with the SP-8-SS shaft collar?

The package contains the two-piece 303 stainless steel collar halves and matching stainless steel clamp screws.

Which bore size should I select for a half-inch shaft?

Choose the 1/2 in bore version; it matches a half-inch shaft and provides a 1 1/8 in outside diameter with 13/32 in width.
