Two-Piece Shaft Collar

The Climax Metal Products 2C-175 is a two-piece clamping collar designed for 1-3/4 inch round shafts. It fits power-transmission assemblies where a solid collar cannot be slipped over the end of a shaft. The split design allows installation or repositioning without removing other mounted components.

Inch-Series Clamping Limits

The collar uses an inch-series bore of 1-3/4 in with a 2-3/4 in outside diameter and a 3 in clearance diameter. Its 11/16 in width and carbon-steel screw provide axial holding power through friction alone. No keyway or threaded bore is present, so torque transmission relies entirely on clamp force.

Carbon Steel Grade 1211 Capacity

The collar body and screw are made from carbon steel grade 1211, offering standard strength for general machine-shop use. It handles typical radial loads and moderate axial thrust in dry, non-corrosive environments. It is not suited for high-cycle shock loads, extreme vibration or applications requiring stainless or alloy steel.

Questions about this item

Which bore size should I select for a 1-3/4 inch shaft?

The 2C-175 is built for a 1-3/4 inch round bore, so it fits that shaft diameter directly.

What does the 2-3/4 inch outside diameter mean when the collar is mounted?

The collar will extend to a 2-3/4 inch outer diameter, giving a 3 inch clearance diameter around the shaft.

How does the 2-piece clamp design affect installation on a finished shaft?

The two-piece construction lets you fit or remove the collar without sliding it along the shaft, using carbon steel screws to clamp it in place.
