Chicago Die Casting 3100 Shaft Collar 1 Inch Bore

Product Description

The CHICAGO DIE CASTING 3100 is a set screw shaft collar designed to secure bearings, sprockets, and other rotating components to a shaft. It locks in place via a slotted headless set screw that engages directly with the shaft surface. This collar is suited for soft shafts or shafts that have been predrilled to accept the set screw tip. Weighing 0.2 pounds, it is a lightweight, compact fastening solution used by millwrights, maintenance technicians, and mechanical contractors working on drive assemblies and rotating equipment.

Set screw shaft collars like the 3100 are commonly found in light-to-medium industrial and commercial applications including conveyor drives, fan shaft assemblies, pump couplings, and general power transmission setups. The collar functions as a mechanical stop or a component retainer depending on the installation requirement. This style is appropriate where shaft marring from the set screw is acceptable or where the shaft has been predrilled to protect the surface.

Key Features

• Set screw locking mechanism holds collar firmly on soft or predrilled shafts
• Furnished with one slotted headless set screw included at time of manufacture
• Functions as a mechanical stop or component retainer on drive shafts
• Lightweight at 0.2 pounds for easy handling in tight drive assemblies
• Compatible with standard 1-inch bore shaft applications

Compatibility

Designed as a standard set screw shaft collar for use on 1-inch diameter soft or predrilled shafts in general power transmission and drive assembly applications.

Installation Notes

Installation is typically performed by a millwright or qualified mechanical technician. De-energize and lock out the drive system completely before positioning or adjusting any shaft collar. The set screw engages the shaft directly, so use only on soft shafts or shafts with a predrilled flat or dimple to avoid shaft damage. A standard hex key is used to tighten the set screw to secure the collar in its intended position.
