Features:
1. Made of quality 6061 aluminum alloy, and surface is anodization, sturdy and durable, shows good shiny, long service life. Provides good stability, high work performance and durability.
2. The set screw type shaft collar has improved holding power when the shaft material is softer than the setscrew material which supports low axial loads and simple positioning. Comes with a socket cup-point setscrew for securing the collar onto the shaft. Double-split collars are made to be softer on the shaft than one-piece collars.
3. The set screw ring is a ring-shaped device. They can also be used as spacers between positioners, mechanical stops and other components.

The two-piece design of the collar allows for better distribution of pressure onto the shaft, reducing the risk of damage or deformation.
5. Shaft rings are often used as stoppers, or to position and hold timing pulleys, etc. Good axial and radial support performance, durable choice for nearly all types of machinery and industry, such as drive shafts, wheel barrow axle, cnc machine tools, agricultural implements, gearbox assemblies, motor bases, steel mill equipment, the automotive industry, the manufacturing industry.
