Climax Metal Products Mod C-256-S Shaft Collar 3-3/4in Od

Product Description

The CLIMAX METAL PRODUCTS MOD C-256-S is a one-piece solid set screw shaft collar machined from 303 stainless steel. It is designed to locate, space, and retain rotating or stationary components on a shaft in industrial and mechanical drive applications. The collar measures 3.75 inches outside diameter and 1.125 inches wide, providing a rigid, positive stop without the need for threading or welding. At 1.62 pounds, the stainless construction resists corrosion in wet, washdown, and mildly corrosive environments. Machinists, millwrights, and maintenance technicians install this collar as part of conveyor systems, pump assemblies, and general power transmission setups.

This collar is suited for light-duty to medium-duty shaft retention tasks in both commercial and industrial settings. The set screw style allows for straightforward installation and repositioning along the shaft without specialized tooling. Common applications include pump shafts, gearbox output shafts, conveyor roller assemblies, and general motion control equipment where a secure, corrosion-resistant shaft stop is required. The plain finish keeps the part ready for direct installation without additional surface prep.

Key Features

• One-piece solid construction provides greater strength than split-style collars under axial load
• Set screw drive style allows tool-accessible installation and repositioning on the shaft
• 303 stainless steel material grade offers good machinability and corrosion resistance
• 3.75 inch outside diameter suits larger shaft and bore applications
• 1.125 inch width provides adequate bearing surface for stable shaft positioning
• Plain finish is installation-ready with no additional prep required

Compatibility

Designed as an OEM-style or aftermarket replacement solid set screw shaft collar for industrial and mechanical drive shaft assemblies requiring a 3.75 inch outside diameter one-piece collar in stainless steel.

Installation Notes

Installation is typically performed by a millwright, maintenance technician, or mechanical assembler using standard hex keys to drive the set screw against the shaft. Always de-energize and lock out the equipment before installing or adjusting shaft collars. Ensure the shaft surface is clean and free of burrs or debris before seating the collar to achieve proper holding force. Follow applicable machinery safety standards and equipment manufacturer procedures when selecting set screw torque and collar placement.
