Climax Metal Products CR2C-250 Clamping Shaft Collar

Product Description

The CLIMAX METAL PRODUCTS CR2C-250 is a two-piece clamping shaft collar manufactured from 1215 steel with a yellow zinc finish. It is designed to secure, locate, and retain components on rotating or stationary shafts in mechanical power transmission systems. The two-piece clamping design allows installation and removal without disassembling adjacent components, making it a practical choice for maintenance-intensive applications. With a 3.75-inch outside diameter and a 0.75-inch width, this collar fits medium-to-large shaft diameters and is suited for industrial machinery, conveyor systems, and pump assemblies.

This shaft collar is used in a wide range of industrial and mechanical installations where positive shaft positioning is required. Typical applications include motor shafts, gearbox assemblies, conveyor lines, and general power transmission equipment. The two-piece clamping style is particularly useful in applications where welding or machining the shaft for set-screw retention is not practical. Mechanical technicians and millwrights commonly install this type of collar during equipment assembly, rebuild, and preventive maintenance work.

Key Features

• Two-piece clamping design allows installation without full shaft disassembly
• 3.75-inch outside diameter suits medium-to-large shaft applications
• 0.75-inch width provides stable axial positioning
• 1215 steel construction for strength and machinability
• Yellow zinc finish provides corrosion resistance in light-duty environments

Compatibility

Designed as an OEM-style replacement or upgrade collar for industrial shaft assemblies requiring a two-piece clamping style with a 3.75-inch outside diameter.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Always de-energize and lock out the equipment before installing or removing shaft collars in accordance with applicable OSHA lockout/tagout procedures. Ensure the shaft surface is clean and free of burrs before seating the collar. Tighten the clamping fasteners evenly to maintain concentricity on the shaft.
