Product Description Product Description Heavy Duty Metal Steel Forged Bearing Block Bushing Housing Babbitt BearingA bearing housing, also known as a bearing pedestal, is a robust and precisely machined structural component designed to support and align a plain bearing (bushing) or rolling-element bearing. It provides a rigid foundation for the rotating shaft, ensuring it remains in the correct position while withstanding heavy radial and axial loads. In critical applications like steam turbines and marine propulsion systems, the bearing housing is essential for maintaining stability, absorbing vibrations, and protecting the bearing from contaminants.Working PrincipleThe bearing housing works by transferring operational loads from the rotating shaft (via the bearing) to the machine's foundation. It rigidly cradles the bearing, maintaining its precise pre-set alignment. The housing absorbs vibrations and shocks, dampening their transmission to the surrounding structure. By enclosing the bearing, it also serves as a reservoir for lubricant and a barrier against external contaminants, ensuring stable and long-lasting bearing performance.Core Features·High Strength and Rigidity: Manufactured from high-grade cast iron or steel, it provides exceptional structural integrity to prevent deformation under extreme loads.·Precise Alignment: Machined with tight tolerances on the bore and mounting surfaces to ensure perfect alignment of the bearing and shaft, reducing wear and vibration.·Efficient Heat Dissipation: Often features ribbed constructions or cooling passages to facilitate the transfer of heat generated by the bearing.·Reliable Sealing and Protection: Integrated sealing grooves accommodate oil seals or gaskets to prevent lubricant leakage and exclude dust, moisture, and other contaminants.Application Scenarios·Steam Turbines: Supports the high-speed rotor shaft in power generation plants.·Marine Propulsion Systems: Supports the propeller shaft and intermediate shafts aboard ships.·Large Pumps and Compressors: Used in critical industrial equipment.Heavy-Duty Gearboxes: Provides support for gears and shafts.Machining ProcessesCasting/ForgingSand casting/closed-die forging → UT inspection (ASTM A609 Class II)Rough MachiningDatum surface turning → 2mm finishing allowanceHeat TreatmentVibration stress relief → Selective induction hardening (case depth 3-5mm)Precision Machining5-axis boring (bore cylindricity ≤0.01mm)Surface grinding (Ra 0.8μm)Assembly VerificationTrial bearing fitting → Runout testing (≤0.02mm TIR)Rough Turning of Datum SurfaceKey Parameter: Leave 2mm finishing allowanceProcess Points:Remove most of the blank allowance using a lathe to establish the reference surface for subsequent machining.Control cutting force and thermal deformation to avoid affecting final dimensional stability.other related products https://cn-totem.en.made-in-china.com/product/ZmlYxFMObfUi/China-Heavy-Duty-Bearing-Housing-for-Mining-and-Construction-Equipment.htmlCompany Profile
