Special Features

  • A bearing steel sleeve is a cylindrical metal component fitted over the outer ring of a bearing or a shaft journal. Its core function is to position the shaft assembly, reduce direct friction between the shaft and bearing housing, while protecting both the shaft and bearing. This extends the overall service life of the equipment, making it a critical supporting component in mechanical transmission systems.
  • Material Requirements: Utilize high-carbon chromium bearing steel as the core material, with carburized bearing steel or stainless steel selected for specific applications. Materials must exhibit high hardness, exceptional wear resistance, good toughness, and fatigue resistance to ensure stable operation under high-speed, high-pressure conditions.
  • Core Characteristics: Features high-precision dimensional tolerances (ensuring optimal clearance fit), low surface roughness (reducing operational resistance), and strong deformation resistance. Certain products undergo heat treatment (quenching and tempering) to enhance hardness and wear resistance, adapting to diverse operational requirements.
  • Application Scenarios: Widely used in mechanical manufacturing (motors, machine tools), automotive industry (engines, transmissions), construction machinery (excavators, cranes), home appliances (air conditioner compressors), and other fields, accommodating the support requirements of various rotating shaft systems.
