Installation instructions for Clamp collar

Split Collars with a locking screw were an outgrowth of threaded adjustable retaining devices made and used by precision instruments and machinery manufacturers in the early twentieth century.

These CLAMP COLLARS are often adequate to position and lock to shaft cams, conveyor rolls, gears, pulleys, sheaves, sprocket and the multitude of other machine components where exacting adjustment is not required to transmit thrust and torque loads. They are great as adjustable shaft spacers or limiters. They become an easy way to create a shoulder eliminating the need to machine expensive keyways, splines and shoulders on rods, shafts, and spindles.

This model is a One piece single slit design, with metric dimension bores, made with low carbon steel with a black oxide finish and blackened alloy steel socket head cap screws.

As with all precision retaining devices, care must be taken during assembly to assure premium performance. Please open and review our installation instructions for proper technique and best results.
