Product Description

This Climax Metal setscrew shaft collar has a two-hole design and is made of black oxide steel. It is a setscrew-type shaft collar for applications supporting low axial loads and simple positioning. Setscrew collars have improved holding power when the shaft material is softer than the setscrew material. This collar has a two-hole design to fit two setscrews; the second setscrew hole is set at 90 degrees from the first hole, enabling the collar to support nearly double the load capacity of a collar with a single setscrew. It is made of steel for weldability and rust resistance with a black oxide finish for a decorative appearance and resistance to white corrosion, chipping and flaking, and stick-slip of the screw during torqueing, improving the collar's grip on the shaft. Black oxide also provides mild corrosion resistance and improved lubricity. This collar comes with a socket setscrew for securing the collar onto the shaft. The operating temperatures for this collar range from -17 to 148 degrees C (0 to 300 degrees F). This shaft collar is suitable for use in various applications, including in the automotive industry to situate components in automobile power steering assemblies, the manufacturing industry to locate components on a conveyor belt system, and the hobby craft industry to hold wheels on axles in remote control vehicles, among others.

Shaft collars are ring-shaped devices primarily used to secure components onto shafts. They also serve as locators, mechanical stops, and spacers between other components. The two basic types of shaft collars are clamping (or split) collars, which come in one- or two-piece designs, and setscrew collars. In both types, one or more screws hold the collars in place on the shaft. In setscrew collars, screws are tightened through the collar until they press directly against the shaft, and in clamping collars, screws are tightened to uniformly compress the collar around the shaft without impinging or marring it. Setscrew collars and one-piece clamping collars must be installed by sliding the collar over the end of the shaft, while two-piece clamping collars separate into two halves and can be installed between components on the shaft. Shaft collars are made from a wide range of materials including zinc-plated steel, aluminum, nylon, and neoprene. Found in nearly every type of machinery and industry, shaft collars are used in applications including gearbox assemblies, motor bases, machine tools, drive shafts, agricultural implements, medical equipment, and paper and steel mill equipment, among others.

Climax Metal Products Company (CLIMAX) manufactures shaft collars, rigid couplings, keyless locking devices, pulleys, keyless bushings, and bearings for the power transmission industry and industrial maintenance, repair, and operations (MRO) markets. The company, founded in 1946, and headquartered in Mentor, OH, meets International Organization for Standardization (ISO) 9001:2008 quality assurance standards.
