5/16 in Shaft Collar Clamp

This carbon steel shaft collar clamp fits a 5/16 inch round bore and secures components on shafts in power transmission assemblies. The one-piece design uses a carbon steel screw for a firm grip without marring the shaft. It measures 11/16 inch outside diameter and 5/16 inch width. Grade 1211 steel provides reliable strength for industrial use.

Suited for inch-system shaft mounting

Mechanics and machine builders needing a simple, inch-dimensioned collar for positioning bearings, sprockets or stops will find this clamp effective. The single-piece construction allows quick installation and removal with basic tools. Buyers requiring a two-piece split collar for assembly without shaft disassembly should consider a different style. Applications needing a keyway or threaded bore are not served by this smooth-bore model.

5/16 in bore diameter decides fit

The critical specification is the 5/16 inch round bore diameter, which must match the shaft exactly for secure clamping. The 0.88 inch clearance diameter and 11/16 inch outside diameter define the space the collar occupies on the shaft. Verify the shaft size before ordering to ensure proper holding power and alignment.

Questions about this item

Which shaft collar version should I choose for a 5/16 inch round shaft?

The 1C-031 is a 1-piece clamp collar with a 5/16 in bore and 11/16 in outside diameter, made from 1211 carbon steel for that exact shaft size.

What does the .88 inch clearance diameter mean when the collar is installed?

The .88 in clearance diameter is the space the collar occupies radially, so adjacent components must stay outside this circle to avoid interference.

How does the clamp screw interface work and what holding force does it provide?

A carbon steel screw tightens the single-piece collar around the shaft, creating a friction grip that secures the 5/16 in bore without marring the shaft surface.
