Purpose and benefits: Provides reliable support compatible withrotating shafts and mounted bearings, reducing shaft wear and improving alignment. Acts as an inner ring replacement compatible withball, needle, and plain bearings, simplifying repairs and retrofits. Chamfered edges and a smooth exterior speed installation and improve seating against housings or mating parts. Key features: Compatible with ball bearings, needle bearings, and plain bearings as the bearing inner sleeve. Can be used as a sleeve on rotating shafts to support bearings or other rotating components. Precision-ground inner and outer diameters with tolerance up to 0.02 mm compatible withaccurate fit and consistent performance. Chamfers and a smooth surface finish enhance fit and reduce installation interference. Performance and fit: Tight diameter tolerance ensures concentricity and stable rotation, minimizing vibration and uneven wear. Smooth external surface and chamfers help achieve secure seating in mechanical housings and ease assembly. Typical applications: Motor repair — replace a worn inner ring on a ball bearing or install as a sleeve on a motor shaft to restore bearing alignment. Gearboxes and reducers — use as an inner sleeve compatible withneedle or plain bearings where precise shaft support and concentricity are required. Industrial machinery maintenance — retrofit rotating components that need a reliable bearing interface without replacing the entire bearing assembly. Installation notes: Chamfers facilitate insertion; gentle press-fit or appropriate assembly tools are recommended to avoid damage. Verify shaft and housing dimensions before installation to ensure compatibility with the specified 0.02 mm tolerance. Why choose this sleeve: Functions both as a bearing inner ring and as a shaft sleeve, offering flexible use in repair and assembly tasks. Precision grinding and tight tolerances provide dependable fit and long-term performance without altering existing bearing types.
