45 mm Carbon-Steel Shaft Collar

This 2-piece clamp collar fits a 45 mm round bore and is made from 1215 carbon steel with alloy-steel screws. It suits maintenance and assembly tasks where a metric shaft must be located or secured without dismantling adjacent components.

Sustained Clamping Performance

The 2-piece design distributes clamping force evenly around the 73 mm outside diameter, maintaining grip under continuous vibration and axial load. Carbon-steel construction resists deformation during prolonged tightening cycles better than single-piece alternatives.

Straightforward Metric Installation

The collar splits into two halves so it can be fitted over an existing 45 mm shaft without removing bearings or gears. Tightening the alloy-steel screws to the recommended torque prevents slippage; over-torquing is the common error that damages the 19 mm wide clamping faces.

Questions about this item

Does the 19 mm wide carbon-steel collar generate noticeable heat or noise when clamped on a shaft that runs continuously?

The collar is a passive mechanical clamp with no moving parts, so it produces no noise and negligible heat during continuous operation.

What shaft diameter and tools are required to install this 2-piece collar?

It fits a 45 mm round shaft and uses alloy-steel clamping screws that are tightened with a standard hex key.

Will the 73 mm outside diameter and 80.1 mm clearance diameter clear adjacent bearings or hubs on older equipment?

The 73 mm OD and 80.1 mm clearance provide a known envelope; compare those dimensions to the spacing on your existing hardware to confirm fit.
