Product DescriptionProduct DescriptionTotem OEM Customized High-Precision Bearing Housing for Industrial ApplicationsA bearing housing is a machine component that supports rotating shafts and their bearings. It ensures secure bearing positioning while facilitating lubrication, thermal management, and contamination protection.Totem OEM Customized High-Precision Bearing Housing are CNC-machined from high-grade steel or ductile iron, ensuring perfect alignment and durability for light-to-medium duty applications. Compatible with standard bearings, these housings feature bolt-on designs for easy installation. Custom bore sizes, mounting holes, and sealing options available.Finished Product ImageSpecificationApplicationsMining Machinery: Uses split-type cast steel bearing housings for impact resistance and easy maintenanceCement Mill: Supports sliding shoe bearings with dust-proof corrosion-resistant designRotary Kiln: Special high-temperature bearing housings with cooling ribsWind Turbine Gearbox: High-precision flanged bearing housings for main shaft bearings to handle complex loadsProduct Features High-Strength Material: 08MnCuNiPS quenched & tempered steel (Tensile strength ≥980MPa) for heavy-duty impact environmentsPrecision Machining: Bearing bore tolerance up to H7 (IT7 grade) for perfect concentricityStrict QC: Ultrasonic testing (UT) for internal defects + mechanical property tests per GB/T 3077Customization: Supports non-standard designs (e.g., enlarged oil grooves, special flange interfaces)Machinery ProcessingManufacturing Process1. Material PreparationRaw material inspection (chemical composition & mechanical testing)Forging/Casting blank forming (42CrMo/GGG50 per ASTM standards)2. Rough MachiningCNC turning for outer contours & mounting surfacesDrilling preliminary bore holes (allowance 2-3mm for finish machining)3. Heat TreatmentQuenching & Tempering (HRC28-32 for 42CrMo)Stress relief annealing to eliminate internal stresses4. Precision MachiningCNC boring for bearing bore (H7 tolerance, Ra≤1.6μm)Milling keyways & bolt holes (±0.02mm positional accuracy)5. Surface TreatmentShot blasting (SA 2.5 grade cleanliness)Optional: Hard chrome plating (15-20μm) or phosphatingDrilling ProcessSurface Finish ProcessMarking & PositioningMark hole centers on the bearing housing according to the drawing.Center DrillingUse a center drill to create pilot holes for alignment.DrillingSelect twist drill or step drill based on hole size.Reaming/FinishingReam or bore the hole for precision tolerance.DeburringRemove burrs to prevent assembly interference.Surface PreparationSandblasting:Achieves Sa 2.5 cleanliness grade (ISO 8501-1 standard)Surface roughness Ra 30-70μm (enhances paint adhesion)Degreasing:Alkaline cleaning agent removes oil/greasePrimer CoatingEpoxy Zinc-rich Primer:Dry film thickness: 60-80μmApplication Method:Airless spray for uniform coverageIntermediate CoatEpoxy MIO (Micaceous Iron Oxide) Paint:Thickness 40-60μmFunctions: UV resistance + micro-porosity fillingTechnical SpecificationsCustom configurations available upon request.Product NameTotem OEM Customized High-Precision Pinion Bearing HousingMaterial08MnCuNiPSProcessingCasting, rough machining, QT, finish machiningHeat treatmentQuenching and temperingSurface treatmenAccording to customer's requirmentsInspectionRaw material inspection, UT, physical property test, dimension inspectCertificationIOS / SGSPackaging & ShippingPackaging Protection1.
