Climax Metal Products 2C-143-S Two Piece Shaft Collar

Product Description

The CLIMAX METAL PRODUCTS 2C-143-S is a two-piece shaft collar designed to locate, space, and retain components on rotating or stationary shafts. With a plain bore diameter of 1.438 inches and an outside diameter of 2.25 inches, this collar provides a secure mechanical stop without requiring shaft modification. The 303-series stainless steel construction offers corrosion resistance suitable for wet, washdown, or mildly corrosive environments. At 0.563 inches wide and weighing 3.27 pounds, the 2C-143-S delivers a compact, solid profile appropriate for industrial drive, pump, and conveyor shaft applications. It is typically installed by millwrights, mechanical technicians, or equipment maintenance professionals.

The 2C-143-S fits shaft applications requiring a 1.438-inch bore with a plain bore type and no keyway. Its two-piece design allows installation and removal anywhere along a shaft without disassembling the entire drive train, making it well suited for positioning bearings, gears, sprockets, and similar components in industrial machinery. The plain finish and stainless steel material make it a practical choice for food processing, marine, chemical, and general industrial environments where corrosion resistance is a priority.

Installation Notes

Installation is typically performed by millwrights or mechanical maintenance technicians. Shut down and lock out all rotating equipment before installing or adjusting shaft collars in accordance with applicable OSHA lockout/tagout procedures. The two-piece design requires tightening both clamping screws evenly to ensure balanced clamping force on the shaft. Verify shaft surface condition and cleanliness before seating the collar to achieve proper holding force.
