Precision 3/16 in 303 stainless shaft collar

This two-piece clamp collar fits a 3/16 in round bore and is machined from 303 stainless steel for corrosion resistance. The 2-piece design allows installation or adjustment without sliding the collar over the shaft end. A stainless steel screw provides the clamping force.

Split construction simplifies shaft mounting

The 5/8 in outside diameter and 9/32 in width keep the profile compact for tight machine assemblies. Clearance diameter of .77 in provides space for adjacent components. Because the collar splits into two halves, it can be positioned or removed on an already-assembled shaft without disassembly of other parts.

Stainless hardware withstands wash-down environments

Both the collar body and the clamping screw are 303 stainless steel, so the assembly resists rust in wet or chemically exposed settings. The solid metal construction transmits torque without the backlash sometimes seen in set-screw types. No lubrication is required for normal operation.

Questions about this item

What bore diameter does the 3/16 in clamp collar accept?

The collar fits a 3/16 in round bore, giving a precise slip fit on standard fractional shafting.

What clearance diameter and width does the 2-piece collar need to seat?

The part measures 0.77 in clearance diameter and 9/32 in wide, so the mounting face must accommodate those dimensions.

How are the stainless steel screws tightened without distorting the 303 SS clamp?

Torque the two socket-head screws evenly in small increments; over-tightening one side first can bind the split and prevent full closure.
