Climax Metal Products H1C-318 Clamp Shaft Collar

Product Description

The CLIMAX METAL PRODUCTS H1C-318 is a one-piece clamp-style shaft collar designed to locate, space, and retain components on rotating or stationary shafts. Machined from steel with a black oxide finish, it delivers corrosion resistance and a clean surface for industrial and mechanical drive applications. The collar measures 4.5 inches outside diameter and 0.875 inches wide, making it suited for larger-shaft assemblies where precise axial positioning is required. Clamp-style collars distribute holding force evenly around the shaft without the stress concentration points associated with set-screw designs. This part is installed by maintenance technicians, millwrights, and mechanical assemblers across a wide range of power transmission setups.

The H1C-318 fits applications involving larger-diameter shafts in industrial machinery, conveyor systems, pump assemblies, and general power transmission equipment. Its one-piece clamp construction allows for tool-assisted tightening without marring the shaft surface, making it appropriate for shafts where surface integrity matters. It is commonly specified in both OEM production builds and MRO replacement scenarios where a reliable, reusable collar is needed at the 4.5-inch shaft interface.

Key Features

• One-piece clamp-style design distributes clamping load evenly around the shaft
• 4.5 inches outside diameter suits larger-shaft mechanical assemblies
• 0.875 inches width provides stable axial positioning along the shaft
• Steel construction with black oxide finish for corrosion resistance
• Reusable and repositionable without damaging shaft surfaces

Compatibility

Designed as an OEM-style clamp shaft collar for use in power transmission and mechanical drive applications requiring a 4.5-inch outside diameter one-piece collar.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. De-energize and lock out all equipment before installing or repositioning the collar. Use the appropriate hex key or wrench to torque the clamp fastener evenly. Verify shaft diameter and surface condition before installation to ensure full clamping engagement.
