Precision 11/16 in Shaft Collar for Machinery Builds

This one-piece clamp collar fits 11/16 in round shafts and is machined from 303 stainless steel for corrosion resistance. It suits maintenance engineers, OEM assemblers and hobbyists who need a secure, reusable shaft stop or component mount in light-duty power-transmission applications.

Clamp-Style Holding Limits on Inch Shafts

The single-screw clamp relies on friction against the shaft surface, so holding power drops on undersized, oversized or soft shafts and under high axial loads or vibration. The 1.56 in clearance diameter and 7/16 in width set the spatial envelope, and the 303 grade is not rated for marine or highly chlorinated environments.

Verify Shaft Size, Material

Confirm the shaft measures exactly 11/16 in diameter with a round, unkeyed surface and that the 1 3/8 in outside diameter clears adjacent parts. Ensure the stainless screw material is compatible with the shaft metal to avoid galling, and note the Proposition 65 notice for California installations.

Questions about this item

Should I pick the 11/16 in bore or a different size?

Choose the 11/16 in bore when your shaft measures exactly 11/16 in; the collar is a single fixed size so it only fits that diameter.

What does the 1.56 in clearance diameter mean once the collar is on the shaft?

The 1.56 in clearance diameter is the space the collar sweeps; keep at least that much room between the collar and any neighbouring part.

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

The 303 stainless steel screw resists corrosion and provides strong clamping force on the 11/16 in shaft without damaging the surface.
