Shaft Collar for 1-15/16 in Shafts

This two-piece clamp collar fits round shafts measuring 1-15/16 in bore diameter. It is made from 303 stainless steel with matching stainless steel screws for corrosion resistance. The collar suits maintenance, repair and OEM assembly where a secure axial stop or component mount is required.

Two-Piece Clamp with 3 in Outside Diameter

The 2-piece construction allows installation or removal without sliding the collar along the full shaft length. A 3 in outside diameter and 3.27 in clearance diameter define the space the collar occupies. The 11/16 in width provides the clamping surface while the round bore has no keyway or threaded features.

Verify Shaft Diameter and Material Compatibility

Confirm the shaft measures exactly 1-15/16 in before ordering because the bore is sized for that dimension only. Ensure 303 stainless steel is acceptable for the operating environment and that the 3 in outside diameter clears adjacent components. The product carries a California Proposition 65 notice for reproductive harm.

Questions about this item

Which bore size should I choose for a 1-15/16 in shaft?

Select the 1-15/16 in bore diameter; the collar is sized specifically for that shaft and clamps evenly around it.

What does the 3.27 in clearance diameter mean when the collar is installed?

The 3.27 in clearance diameter is the space the two-piece collar occupies radially, so adjacent components must stay outside that circle.

How does the 2-piece clamp design with stainless steel screws perform on a 303 stainless collar?

The 2-piece construction lets you install or remove the collar without sliding it along the shaft, and the matching stainless screws resist galling in 303 stainless.
