2-Piece Aluminium Clamp Collar

This 2-piece clamp collar is made from 2024 aluminium and fits a 7/8 inch round bore. The two-piece construction allows installation or removal without sliding the collar along the shaft, saving time during maintenance or adjustment.

Suited for light-duty positioning and spacing

The aluminium material keeps weight low and resists corrosion in typical workshop environments. It is not intended for high-torque locking or heavy axial loads where a steel collar or keyed connection would be required.

Bore 7/8 in with 1.92 in clearance diameter

The collar accepts a 7/8 inch shaft and provides a clearance diameter of 1.92 inches. The 1/2 inch width distributes clamping force across the bore. Available torque and axial holding capacity are limited by the aluminium material and screw size.

Questions about this item

What shaft diameter must I already have for this 7/8 in bore collar to fit?

The collar accepts a round shaft measuring exactly 7/8 in diameter.

Will the 1.92 in clearance diameter clear the adjacent components on my existing assembly?

The 1.92 in clearance diameter provides space around the collar; verify your neighbouring parts allow at least that envelope.

How can I confirm the 2-piece clamp is secured correctly after installation?

Tighten the alloy-steel screws until both halves meet evenly and the collar no longer rotates or slides on the shaft.
