Climax Metal Products H2C-312 Shaft Collar 4.5in Od

Product Description

The CLIMAX METAL PRODUCTS H2C-312 is a two-piece clamping shaft collar manufactured from 1215-grade steel with a black oxide finish. It features a 4.5-inch outside diameter and a width of 0.875 inches. The two-piece clamping design allows the collar to be installed or repositioned on a shaft without requiring disassembly of adjacent components, making it a practical choice for industrial and mechanical power transmission applications. Licensed machinists, millwrights, and maintenance technicians typically install this type of collar in motor, pump, and conveyor shaft assemblies.

This collar is suited for shaft positioning, load bearing, and component retention in both light and moderate-duty mechanical assemblies. The clamping style provides a secure, non-marring grip on the shaft compared to set-screw designs, reducing the risk of shaft damage under dynamic loads. It is commonly specified in commercial and industrial equipment where shaft access is limited and frequent repositioning may be required.

Key Features

• Two-piece clamping design allows installation and removal without full shaft disassembly
• 4.5-inch outside diameter suits larger shaft applications requiring positive axial retention
• 0.875-inch width provides a stable bearing surface along the shaft
• 1215-grade steel construction offers good machinability and consistent dimensional tolerance
• Black oxide finish provides mild corrosion resistance and reduces light glare in service environments

Compatibility

Designed as an OEM-style replacement or direct-fit shaft collar for industrial power transmission assemblies requiring a two-piece clamping style with a 4.5-inch outside diameter.

Installation Notes

Installation should be performed by a qualified millwright or maintenance technician. De-energize and lockout the drive system before working on any rotating shaft assembly, following applicable OSHA lockout/tagout procedures. Ensure the shaft surface is clean and free of burrs before positioning the collar. Torque the clamping fasteners evenly to seat the collar squarely on the shaft.
