Shaft Collar 1-7/16 in Stainless Steel 303

This two-piece shaft collar fits a 1-7/16 inch round bore and is made from 303 stainless steel. It suits maintenance tasks where the shaft cannot be removed and a secure clamping force is required. Builders who need a one-piece design or a different bore size should look elsewhere.

Sustained clamping performance

The 2-piece construction distributes clamping pressure evenly around the shaft without marring the surface. Carbon steel screws provide the holding force while the stainless body resists corrosion in wet or chemical environments. The collar maintains its grip under continuous vibration and axial loads typical of power transmission assemblies.

Thermals noise and power draw

As a passive mechanical component the collar generates no heat, consumes no power and produces no audible noise during operation. Its 303 stainless steel material remains dimensionally stable across normal ambient temperature ranges. The carbon steel screws should be checked periodically for proper torque in high-cycle applications.

Questions about this item

Does the carbon-steel screw on the 2C-143-S heat up or make noise when the shaft runs all day?

The screw is static carbon steel; it does not generate heat or noise during continuous rotation.

What shaft diameter must I already have for this 1-7/16 in bore collar to clamp correctly?

A round shaft measuring exactly 1-7/16 inches is required for proper fit.

Will the 2-1/4 in outside diameter clear the same space as my old single-piece collar?

The two-piece design has a 2-1/4 in OD and 2.5 in clearance diameter, so it needs at least that much radial room.
