This 1 piece assembly is designed for precise positioning and secure retention along an optical axis. It combines multiple small components into a single, compact unit to support accurate alignment, stable clamping, and reliable axial fixation in precision machinery and fixtures. Key benefits Precise optical axis positioning: enables stable alignment and reduced runout in optical or spindleguided setups. Secure retention and clamping: builtin locking and retaining features minimize axial movement and overtravel. Simplified assembly: combines several common ring and bearing functions into one part, reducing parts count and assembly time. Versatile construction: suitable for applications requiring a fixed spindle, bearing support, and ringbased positioning in a compact form. Key attributes Quantity: 1 piece (1PCS) Size: Scsaw 15x35x12 Components included: separate optical axis fixed ring, locking ring, limit ring, bearing, fixed spindle, retaining ring, bushing, positioning ring, clamping Material: not specified in the product listing Functionality: fixed ring, locking ring, limit ring, bearing, fixed spindle, retaining ring, bushing, positioning ring, and clamping integrated in a single part Compatibility: exact compatibility with specific spindles, bores, or fixtures is not stated; please verify against your equipment's specifications Performance: designed to support accurate axis positioning and secure axial retention in a compact form Applications Optical axis alignment in precision machining or inspection setups where stable axis reference is required Spindle or bearing positioning in fixtures that demand fixed axial location and reliable clamping Compact assemblies in CNC or automated tooling where multiple ring and bearing functions need to be combined in one unit Notes Material details are not provided in the listing; confirm material compatibility with your application before use Review your equipment's bore, spindle, and spacing requirements to ensure proper fit with the size Scsaw 15x35x12 This description reflects the product's stated brand, specifications, model, and features as listed, without introducing additional details.
