  • 1 inch bore matches common shaft sizes
  • Carbon steel screws lock collars securely

One-Inch Bore Aluminum Shaft Collar

This two-piece clamp-style shaft collar fits a 1 in round bore and is machined from 6061 aluminum. It provides axial positioning or component retention on inch-dimension shafts in machinery and automation assemblies. The split design allows installation or adjustment without sliding the collar over the shaft end.

Two-Piece Clamp for Quick Mounting

The 2-piece construction clamps around the shaft with carbon-steel screws, so the collar can be fitted or repositioned without removing bearings, gears or other mounted parts. A 1/2 in collar width and 2.06 in clearance diameter keep the profile compact while still delivering a secure grip on the shaft surface.

Lightweight Aluminum with Steel Fasteners

The 6061 aluminum body reduces rotating mass compared to steel collars, while the carbon-steel clamp screws supply the necessary holding force. In normal operation the collar runs without lubrication and adds minimal inertia to the drivetrain.

Questions about this item

Will the 2-piece clamp design with carbon-steel screws hold a 1 in shaft without slipping under sustained torque?

The 2-piece aluminum collar clamps evenly around the shaft and the carbon-steel socket-head screws provide high holding power; proper torque on both screws keeps the 1 in bore secure during continuous operation.

Does the aluminum 6061 collar stay cool and quiet when the shaft runs all day at speed?

Aluminum 6061 dissipates heat quickly and the collar has no moving parts, so it adds negligible friction, noise or temperature rise during extended use.

What tools and shaft preparation are needed before installing this collar?

You need a hex key that fits the carbon-steel socket-head screws and a clean, round 1 in shaft free of burrs or keyways for the clamp to grip properly.
