Shaft Collar for 1 Inch Round Bores

This two-piece aluminum collar clamps onto a 1 inch round shaft without keyway or thread. The 2024 grade alloy provides a high strength-to-weight ratio for motion assemblies. Alloy steel screws supply the clamping force.

Replaces One-Piece Collars on Assembled Shafts

The split design installs around bearings, gears or pulleys without sliding components off the shaft end. The jump is worth it when disassembly would add labour time or risk alignment loss on precision equipment.

Fits Builds Needing 2.03 Inch Clearance Diameter

The collar measures 1 3/4 inch outside diameter and 1/2 inch width, leaving space for adjacent hardware. Aluminium construction reduces rotating mass compared to steel alternatives. Proposition 65 listed chemicals are present.

Questions about this item

Will the 2.03 in clearance diameter fit inside my housing bore?

The two-piece collar has a 2.03 in clearance diameter, so the housing bore must be larger than that to allow the clamp halves to pass through.

Which screw size and torque should I use when clamping the 1 in bore?

Tighten the alloy-steel socket-head cap screws evenly in a cross pattern to the torque recommended for that screw size; uneven tightening distorts the 2024 aluminum clamp.

How often should I re-check the clamp screws on the 2024 aluminum collar?

Re-torque the alloy-steel screws after the first few hours of operation and then at regular maintenance intervals to maintain grip on the 1 in shaft.
