Climax Metal Products C-181-A Shaft Collar 2.75 in Aluminum

Product Description

The CLIMAX METAL PRODUCTS C-181-A is a set screw style shaft collar designed to locate, space, and retain components on rotating or stationary shafts. Machined from aluminum, this collar offers a lightweight, corrosion-resistant option for applications where weight reduction matters. It measures 2-3/4 inches in outside diameter and 7/8 inches wide, making it a compact and precise fit for the intended shaft size. Shaft collars of this type are installed by mechanical technicians, maintenance professionals, and machine builders working on motors, conveyors, pumps, and general power transmission assemblies.

This collar is suited for light-to-medium duty industrial and commercial applications where a reliable shaft-stopping or component-spacing solution is needed. The set screw fastening method allows for straightforward installation and repositioning along the shaft without the need for keyways or special tooling. It is commonly used in motor shaft assemblies, conveyor systems, pump drives, and general mechanical power transmission setups where aluminum construction is appropriate for load and environmental conditions.

Key Features

• Set screw fastening style for quick installation and adjustable positioning along the shaft
• Aluminum construction provides a lightweight and corrosion-resistant build
• 2-3/4 inch outside diameter with 7/8 inch width for precise shaft fitment
• Compact profile suitable for space-constrained assemblies
• Single-piece construction with no moving parts for reliable long-term performance

Compatibility

Designed as an OEM-style replacement or drop-in shaft collar for mechanical assemblies requiring a 2-3/4 inch outside diameter set screw collar in aluminum construction.

Installation Notes

Installation is typically performed by a qualified millwright, maintenance technician, or machine builder. Power down and lock out all equipment before servicing any shaft assembly. Use the appropriate hex key or Allen wrench to tighten the set screw to the manufacturer recommendation for the shaft material. Avoid over-tightening, which can deform the shaft or strip the set screw threads.
