Climax Metal Products CR2C-243 Clamping Shaft Collar

Product Description

The CLIMAX METAL PRODUCTS CR2C-243 is a two-piece clamping shaft collar designed to secure rotating shafts in mechanical drive systems. Machined from 1215 grade steel with a yellow zinc finish, it delivers corrosion resistance alongside solid clamping force. The collar measures 3.5 inches outside diameter and 0.75 inches wide, making it well suited for medium-duty shaft retention applications. Licensed millwrights, maintenance technicians, and mechanical contractors install this type of collar during assembly, alignment, and positioning tasks on rotating equipment.

This collar fits into conveyor systems, pump assemblies, gear drives, and general power transmission equipment where a two-piece clamping design is preferred over set-screw styles. The two-piece construction allows installation and removal without having to disassemble adjacent components, which reduces downtime during maintenance cycles. It is appropriate for both new installations and replacement work in industrial and commercial mechanical systems.

Key Features

• Two-piece clamping design allows installation and removal without full shaft disassembly
• 3.5 inches outside diameter suits medium-duty rotating shaft applications
• 0.75 inches width provides stable axial positioning along the shaft
• 1215 grade steel construction offers consistent machinability and strength
• Yellow zinc finish provides corrosion resistance in typical shop and mechanical room environments

Compatibility

Designed as an OEM-style replacement or new-installation shaft collar for medium-duty rotating equipment requiring a two-piece clamping style collar with a 3.5 inch outside diameter.

Installation Notes

Installation is typically performed by a licensed millwright or qualified maintenance technician. Isolate and lock out all power to the drive system before handling any shaft-mounted components. Use calibrated torque tools per the equipment manufacturer specifications when tightening clamping hardware. Confirm shaft diameter and collar bore fit before final assembly to avoid improper seating.
