One piece fixed ring assembly designed to function as a separable optical axis fixed ring, locking ring, limit ring, bearing retainer, spindle retaining ring, bushing positioning ring and clamping device. Size: Scsaw 25x45x12. This component is intended to help secure and align small spindle or bearing assemblies with a simple, reliable clamping action. Key benefits Improves alignment stability: holds components in precise position to maintain a fixed optical axis during operation. Simple installation and removal: single piece design allows quick mounting and replacement without complicated assembly. Multi function utility: combines locking, bearing retention, bushing positioning and clamping in one ring, reducing the need for multiple parts. Compact and versatile: suitable for compact spindle and bearing arrangements where space is limited. Consistent positioning: helps minimize play or movement that can affect precision and repeatability. Key attributes Functionality: fixed ring with locking, limit and bearing retaining features; also serves as bushing positioning and clamping ring. Compatibility: designed for applications requiring a separate optical axis fixed ring with the specified size. Size: Scsaw 25x45x12. Material: not specified in listing. Performance: provides secure positioning to support stable alignment in precision assemblies. Specifications and notes Size: Scsaw 25x45x12. Quantity: 1 piece. Material: not specified in listing. How it works The ring is mounted around a spindle or bore to fix position, lock components in place, and retain bearings or bushings. When tightened or clamped, it resists axial or radial movement to preserve alignment along the optical axis. The design supports positioning of bushings and related components, helping to maintain consistent spacing and reference points. Applications and use cases Precision spindle assemblies: use as a retaining and clamping ring to fix the spindle bearing position and maintain optical axis alignment in small machine tools. Optical or precision instrumentation: suitable for positioning and locking components along the optical axis in compact assemblies. General mechanical fixtures: can be used as a limit ring and bearing retainer in small, spaceconstrained systems requiring stable, repeatable positioning. What you get 1 piece fixed ring assembly with multiple functional roles (locking, limit, bearing retention, bushing positioning, clamping) in a single component. Size specification: Scsaw 25x45x12. Maintenance and care Inspect for wear or corrosion during routine maintenance. Clean with appropriate nonabrasive cleaners; avoid harsh chemicals that may affect material integrity. Ensure correct installation torque and seating to maintain alignment and performance. Compatibility considerations Verify that the component's size matches the target spindle, bearing, and bushing dimensions for your fixture or device. Confirm that the design aligns with your optical axis alignment requirements and spacing needs. Note Material and certain performance specifications are not provided in the listing. When selecting this part, confirm that Scsaw 25x45x12 meets your exact mechanical, thermal, and material compatibility requirements before use.
