Climax Metal Products C-156-BO Shaft Collar 1.563in Bore

Product Description

The CLIMAX METAL PRODUCTS C-156-BO is a set screw shaft collar designed for shaft positioning, axial load retention, and component spacing in industrial and mechanical drive systems. Built from steel with a black oxide finish, this collar features a plain bore diameter of 1.563 inches and an outside diameter of 2.5 inches. The 13/16-inch width provides a compact profile suitable for confined shaft arrangements. Licensed mechanical and maintenance tradespeople install this type of collar across a wide range of rotating equipment applications.

This collar is suited for use in HVAC blower assemblies, pump shafts, conveyor systems, and general industrial machinery where reliable shaft retention is required. The set screw locking style allows secure fastening without requiring a keyway, making it compatible with plain bore shafts in both new installations and retrofit scenarios. The black oxide finish offers moderate corrosion resistance for indoor and protected environments.

Installation Notes

Installation is typically performed by licensed millwrights, mechanical technicians, or HVAC service professionals. De-energize and lock out all power to the equipment before working on any rotating shaft assembly. A properly sized hex key or Allen wrench is required to tighten the set screw; refer to the collar manufacturer specifications for appropriate fastener torque guidance. Ensure the shaft surface is clean and free of burrs before seating the collar to achieve proper retention.
