Shaft Collar for 1-7/8 Inch Bore

The Climax Metal Products H2C-187 is a two-piece clamp-style shaft collar designed for inch-series shafts with a 1-7/8 inch bore diameter. It suits maintenance and assembly tasks where a secure, removable shaft attachment is required without marring the shaft surface.

Capacity and Operating Limits

The collar accepts a 1-7/8 inch shaft and provides a 3.25 inch clearance diameter with a 5/8 inch width. It operates reliably from 0 to 300 degrees Fahrenheit. The steel construction with black oxide finish resists corrosion, but the clamp design is not intended for axial loads beyond the holding power of the two 5/16-24 socket-head screws.

Included Hardware and Effect

Two steel socket-head cap screws, size 5/16-24 by 1 inch, are supplied with the collar. Using the provided screws ensures proper thread engagement and clamping force; substituting other fasteners can reduce holding strength or damage the clamp halves.

Questions about this item

Will the 1-7/8in bore fit a shaft I already have that measures 1 7/8 in?

Yes, the collar is manufactured with a plain bore diameter of 1 7/8 in to match that shaft size exactly.

How can I verify the clamp is holding correctly once installed?

Tighten the 5/16 in.-24 x 1 steel socket-head screw to the recommended torque; the two-piece clamp will close evenly around the shaft without marring the surface.

What comes in the box and is any additional hardware needed?

The package contains the black-oxide steel collar and the matching 5/16 in.-24 x 1 screw; no extra fasteners or tools are required beyond a standard hex key.
