Climax Metal Products H2C-343 Clamp Shaft Collar Steel

Product Description

The CLIMAX METAL PRODUCTS H2C-343 is a two-piece clamp-style shaft collar designed to locate, space, and retain rotating or stationary components on a shaft. It features a plain bore diameter of 3.438 inches and an outside diameter of 4.75 inches, with a width of 0.875 inches. Constructed from steel with a black oxide finish, it provides corrosion resistance and a consistent surface for industrial and mechanical applications. The two-piece design allows installation and removal without disassembling adjacent components, making it a practical choice for maintenance-focused installations.

This shaft collar is suited for use in industrial machinery, conveyor systems, pump assemblies, and similar power transmission setups where secure shaft positioning is required. The H2C series clamp-style design distributes clamping force evenly around the shaft, reducing the risk of shaft damage compared to set-screw alternatives. It is typically installed by millwrights, maintenance technicians, or mechanical assemblers working on rotating equipment in commercial and industrial environments.

Key Features

• Two-piece clamp design allows installation without full shaft disassembly
• Plain bore diameter of 3.438 inches for direct shaft fit
• Outside diameter of 4.75 inches with a width of 0.875 inches
• Steel construction with black oxide finish for corrosion resistance
• Manufactured under ISO 9001:2008 quality standards
• H2C series clamp collar for even clamping force distribution

Compatibility

Designed as an OEM-style replacement or direct-fit shaft collar for power transmission assemblies requiring a 3.438-inch bore diameter clamp-style collar in the H2C series.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician familiar with rotating shaft assemblies. Power down and lock out the equipment before installing or removing the collar. The two-piece design requires even torquing of the clamping fasteners to ensure proper seating and shaft retention. Verify shaft surface condition and diameter tolerance before installation to ensure a secure fit.
