1-Piece Steel Bearing Sleeve, 35 × 45 × 26.5 mm, 28/30/32/35/37 mm Inner Diameter Options

Description

• Made of high-carbon GCr15 chromium bearing steel with HRC5862 hardness after special quenching and tempering treatment.
• Controlled chromium content improves rust resistance and reduces oxidation and corrosion in humid and dusty environments.
• Inner and outer diameter tolerances are strictly controlled to IT5IT6, with 0.005 mm roundness error and 0.01 mm end-face parallelism.
• Surface roughness is Ra0.4Ra0.8 m, reducing friction and component wear.
• Burr-free chamfers on both ends improve installation safety and convenience.
• Withstands radial loads of 5,00015,000 N, depending on the specification.
• Suitable for small and medium-sized equipment, with resistance to deformation and breakage.
• Stable performance from 20C to 120C and a low thermal expansion coefficient.
• Commonly used in industrial equipment, automotive systems, and household appliances.

The inner and outer diameter tolerances are within IT5IT6, with a roundness error of 0.005 mm and end-face parallelism of 0.01 mm. This ensures a secure fit during bearing installation and helps prevent transmission noise or vibration caused by excessive clearance. The inner and outer diameter surface roughness reaches Ra0.4Ra0.8 m. This reduces friction with bearings and journals, lowers energy loss during operation, minimizes component wear, and improves the overall stability of the transmission system. Precisely formed chamfers on both ends provide smooth, burr-free edges. This helps prevent scratches to bearing seals or operating components during installation and improves installation safety and convenience.
