Clamp-On Shaft Collar 2-Pack, Split Fixed Ring for Optical Axis, Alloy Steel & Aluminum, Easy Installation & Removal, Automotive & Industrial Use (Inner Diameter 80*Outer Diameter 108*Thickness 19)

This 30-series stainless steel open-type retaining ring is a precision shaft positioning fixture made of SUS304 stainless steel, designed for axial fixation and spacing of components on smooth shafts. It features a split, open-type structure for tool-free installation, with a precision-polished, burr-free surface that ensures a secure, scratch-free fit. Available in standard dimensions with a DIN inner diameter of 30mm, an outer diameter of 45mm, and a thickness of 15mm, it offers high hardness and corrosion resistance for long-term use in humid or corrosive environments. The ring functions as both a component fixer (for wheels, bearings) and a baffle to limit axial movement, making it suitable for automation equipment, conveyors, CNC machines, and textile systems that demand reliable shaft positioning.
