Product Description

Totem OEM Customized High-Precision Bearing Housing for Industrial Applications

A 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.

Applications

Mining Machinery: Uses split-type cast steel bearing housings for impact resistance and easy maintenance
Cement Mill: Supports sliding shoe bearings with dust-proof corrosion-resistant design
Rotary Kiln: Special high-temperature bearing housings with cooling ribs
Wind Turbine Gearbox: High-precision flanged bearing housings for main shaft bearings to handle complex loads

Product Features 
High-Strength Material: 08MnCuNiPS quenched & tempered steel (Tensile strength ≥980MPa) for heavy-duty impact environments
Precision Machining: Bearing bore tolerance up to H7 (IT7 grade) for perfect concentricity
Strict QC: Ultrasonic testing (UT) for internal defects + mechanical property tests per GB/T 3077
Customization: Supports non-standard designs (e.g., enlarged oil grooves, special flange interfaces)

Machinery Processing

Manufacturing Process

1. Material Preparation
Raw material inspection (chemical composition & mechanical testing)
Forging/Casting blank forming (42CrMo/GGG50 per ASTM standards)
2. Rough Machining
CNC turning for outer contours & mounting surfaces
Drilling preliminary bore holes (allowance 2-3mm for finish machining)
3. Heat Treatment
Quenching & Tempering (HRC28-32 for 42CrMo)
Stress relief annealing to eliminate internal stresses
4. Precision Machining
CNC boring for bearing bore (H7 tolerance, Ra≤1.6μm)
Milling keyways & bolt holes (±0.02mm positional accuracy)
5. Surface Treatment
Shot blasting (SA 2.5 grade cleanliness)
Optional: Hard chrome plating (15-20μm) or phosphating

Drilling Process

Surface Finish Process

Marking & Positioning
Mark hole centers on the bearing housing according to the drawing.
Center Drilling
Use a center drill to create pilot holes for alignment.

Drilling
Select twist drill or step drill based on hole size.
Reaming/Finishing
Ream or bore the hole for precision tolerance.

Deburring
Remove burrs to prevent assembly interference.

Surface Preparation
Sandblasting:Achieves Sa 2.5 cleanliness grade (ISO 8501-1 standard)
Surface roughness Ra 30-70μm (enhances paint adhesion)
Degreasing:Alkaline cleaning agent removes oil/grease

Primer Coating
Epoxy Zinc-rich Primer:Dry film thickness: 60-80μm
Application Method:Airless spray for uniform coverage

Intermediate Coat
Epoxy MIO (Micaceous Iron Oxide) Paint:Thickness 40-60μm
Functions: UV resistance + micro-porosity filling
