Climax Metal Products 2C-243 Split Shaft Collar 2.438in Bore

Product Description

The CLIMAX METAL PRODUCTS 2C-243 is a two-piece split shaft collar designed for precise shaft positioning, clamping, and component retention in rotating machinery. With a 2.438-inch plain bore diameter and a 3.5-inch outside diameter, this collar fits mid-to-large shaft assemblies common in industrial drives, conveyor systems, and mechanical power transmission equipment. The steel construction with a black oxide finish provides corrosion resistance and durability under standard service conditions. At 0.96 pounds, it is solid enough for reliable clamping without adding excessive mass to the assembly. The two-piece split design allows installation and removal without disassembling adjacent components.

This collar is used wherever a shaft requires a positive mechanical stop or component spacer on a 2.438-inch diameter shaft. Typical applications include industrial motors, gearboxes, pumps, and conveyor drive shafts in both light and heavy manufacturing environments. The two-piece split configuration is well suited for installations where the shaft cannot be accessed from an end. Mechanical maintenance technicians and machine builders install this type of collar during initial assembly and field retrofits. The 0.75-inch width provides a stable clamping face without excessive axial space requirements.

Designed as a two-piece split shaft collar for 2.438-inch diameter shafts in industrial mechanical assemblies. No specific equipment model compatibility was provided in the product data.

Installation Notes

Installation is performed by mechanical technicians. De-energize all connected motors and lock out power before working on any rotating shaft assembly per LOTO procedures. The two-piece split collar halves are positioned around the shaft and fastened with the provided hardware to the manufacturer torque specification found on the fastener documentation supplied with the part. Confirm proper shaft surface condition and ensure the collar seats squarely before final tightening.
