This singlepiece component combines multiple ring and bearing features to support precise axial positioning and secure retention in spindle and bearing assemblies. It is described as a separate optical axis fixed ring, locking ring, limit ring, bearing fixed spindle, retaining ring, bushing, positioning ring, and clamping element. The size is Scsaw 8x25x8. Key benefits Enables precise optical axis alignment and stable axial positioning, reducing runout and movement in assemblies. Provides secure retention and locking to prevent unintended axial shift of spindles and bearings. Offers a versatile combination of functions (fixed ring, locking ring, limit ring, retaining ring, bushing, positioning ring, and clamping) in a single component for streamlined assembly. Compact size Scsaw 8x25x8 makes it suitable for small to midsize machinery and fixtures without adding bulk. Key attributes Functionality: separate optical axis fixed ring; locking ring; limit ring; bearing fixed spindle; retaining ring; bushing; positioning ring; clamping Compatibility: designed for assemblies with the Scsaw 8x25x8 footprint; compatible with related spindle and bearing components requiring axial positioning and retention Size: Scsaw 8x25x8 Material: not specified in the listing Performance: not specified in the listing Quantity: 1 piece (1PCS) Applications and use cases Spindle assemblies in small CNC machines or milling devices where axial retention and precise alignment are critical.
