Technical Specifications and Parameters

Understanding the technical specifications of steel bearing housing is crucial for proper selection and integration into machinery. These parameters dictate the housing's compatibility, load-bearing capacity, sealing effectiveness, and overall operational longevity. Our AH Flanging Bearing Housing, for instance, exemplifies precision engineering designed for demanding applications.

The precise design of the bearing seat, often machined to IT5 or IT6 tolerance classes, is crucial for preventing fretting corrosion and ensuring proper load distribution across the bearing. The robust wall thickness and strategic reinforcement ribs of a typical steel bearing housing contribute to its high rigidity, minimizing deflection under heavy loads and reducing vibration, thereby extending the service life of the contained bearing.

Furthermore, the integration of effective sealing arrangements is non-negotiable. For a sealed bearing housing, multi-stage labyrinth seals or advanced contact seals are often employed to prevent ingress of dust, moisture, and other contaminants, especially critical in harsh operating environments such as mining or cement plants. This meticulous attention to detail in material selection, machining, and sealing design differentiates high-quality steel bearing housing from conventional alternatives.
