1-Piece Carbon-Steel Shaft Collar

The Climax Metal Products C-075X3 is a 1-piece set-screw collar machined from 1211 carbon steel. It fits a 3/4 in round bore and has a 1.25 in outside diameter with a 9/16 in width. The pack contains three collars for multiple shaft locations.

Maintenance teams and OEM assemblers

Maintenance teams and OEM assemblers who need a simple axial stop on inch-dimension shafts will find the 1-piece design quick to install with a single set screw. Applications requiring a 2-piece split collar, a keyway, or a different bore size should look at other collar styles.

Carbon steel holds position under steady torque

Carbon steel holds position under steady torque and the single set screw maintains clamping force during continuous rotation. The 1-piece construction avoids the joint line that can loosen under prolonged vibration, so the collar stays fixed without frequent re-tightening.

Questions about this item

Does the 3/4 in bore fit directly on my existing shaft without a keyway?

The collar has a round 3/4 in bore with no keyway, so it slides onto a plain shaft of that diameter and clamps via the set screw.

Can I use these carbon-steel collars on the same shaft as older stainless components?

Yes, the 1211 carbon steel material will not interfere mechanically with stainless parts, though galvanic corrosion is possible in wet environments.

How do I confirm the 1.25 in outside diameter clears my adjacent brackets after installation?

Measure the gap between brackets; the collar’s 1.25 in OD and 9/16 in width must both fit within that space when the set screw is tightened.
