20 mm Aluminium Quick-Clamp Shaft Collar

This one-piece aluminium collar fits a 20 mm round bore and clamps with a single stainless-steel screw. The 6061-grade alloy body is 13 mm wide with a 50 mm outside diameter, making it suitable for positioning components on metric shafts in light-duty applications.

Clamping behaviour under sustained load

The quick-clamp lever sits 25 mm from the centreline, allowing rapid tightening and release without tools. Under continuous vibration or axial force the single screw maintains holding power, though the 1-piece design relies on the clamp force alone rather than a split-ring mechanical lock.

Compatibility checks before ordering

Verify that the shaft diameter is exactly 20 mm and that the 50 mm outside diameter clears adjacent parts. Ensure the 13 mm collar width fits the available axial space and that the operating environment is compatible with aluminium 6061 and stainless steel.

Questions about this item

Does the 1-piece quick-clamp design add noticeable heat or noise when the shaft runs continuously?

The aluminum 6061 collar with stainless-steel screw is a passive mechanical component; it generates no heat or noise of its own during all-day operation.

What shaft diameter must I already have for the 20 mm bore to fit?

You need a round shaft measuring exactly 20 mm in diameter for the bore to clamp correctly.

Will the 50 mm outside diameter and 13 mm width clear the bearings and brackets on my existing 20 mm shaft assembly?

The collar’s 50 mm OD and 13 mm width sit on the shaft; verify your adjacent components allow that radial and axial space.
