Climax Metal Products 1C-125-S Clamp Shaft Collar

Product Description

The CLIMAX METAL PRODUCTS 1C-125-S is a one-piece clamp-style shaft collar manufactured from 303 stainless steel. It features a 1.25-inch plain bore diameter and a 2-1/16-inch outside diameter, with a width of 0.5 inches. Clamp collars secure components on rotating or stationary shafts without set screws, distributing clamping force evenly around the shaft to minimize surface damage. This collar is suited for use in mechanical assemblies, conveyor systems, pump shafts, and other power transmission applications where corrosion resistance and reliable axial positioning are required. Machinists, millwrights, and mechanical technicians are the primary installers.

This collar is appropriate for use in both light industrial and commercial mechanical systems wherever a 1.25-inch shaft diameter is present. Its 303 stainless steel construction makes it a strong choice in wet, washdown, or corrosive environments where carbon steel collars would be prone to rust or staining. Typical installations include pump assemblies, food processing equipment, and marine or outdoor machinery. The plain bore accepts standard unthreaded shafts and pairs with a clamping fastener to lock the collar axially in position.

Key Features

• One-piece clamp design distributes clamping load evenly, reducing shaft marring compared to set-screw collars
• 303 stainless steel construction provides corrosion resistance in wet or chemically exposed environments
• 1.25-inch plain bore diameter for use on standard unthreaded shafts
• 2-1/16-inch outside diameter with 0.5-inch width for a compact axial footprint
• Plain finish with no secondary coating, compatible with the natural surface of 303 stainless
• Manufactured under ISO 9001:2008 quality standards

Compatibility

Designed as an OEM-style replacement or direct-fit collar for mechanical assemblies using a 1.25-inch diameter shaft, consistent with Series 1C clamp collar specifications.

Installation Notes

Installation is typically performed by a millwright, machinist, or mechanical technician using standard hand tools. Always de-energize and lock out the equipment before installing or repositioning shaft collars. Position the collar at the desired axial location on the shaft before tightening the clamp fastener to the hardware manufacturer's recommended torque. Avoid overtightening, which can distort the bore or damage the shaft surface.
