Climax Metal Products 1C-125 Shaft Collar 1-1/4 in Steel

1-1/4 Inch Steel Shaft Collar

This Climax Metal Products shaft collar clamps onto a 1-1/4 inch round bore using a single-piece carbon steel construction. The collar features a 2 1/16 inch outside diameter and a 1/2 inch width. Grade 1211 carbon steel provides the material basis for both the collar body and the clamping screw. It functions as a mechanical stop, spacer or component mount on inch-system shafts.

Builders needing a 1-1/4 inch clamp collar

Maintenance crews and machine builders securing components on 1-1/4 inch shafts will find this collar matches the required bore size and inch measurement system. The one-piece clamp design suits applications where a solid ring can be slid over the shaft end. Buyers who need a two-piece split collar for mid-shaft installation without disassembly should look at a different style. Applications requiring a keyway, threaded bore or a different bore diameter also need an alternative part.

1-1/4 inch round bore diameter

The critical specification is the 1-1/4 inch round bore diameter, which must match the shaft outer diameter exactly for the clamp to function. The collar uses a 2.31 inch clearance diameter and grade 1211 carbon steel construction. Verifying the shaft size against this bore measurement is the single step that determines whether this specific collar fits the application.
