Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 131.32.2000.03 Three-row Cylindrical Roller Slewing Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Beyond standard alloy steel, CHG Bearing can customize the 131.32.2000.03 Three-row Cylindrical Roller Slewing Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
To ensure optimum performance of CHG Bearing 131.32.2000.03 Three-row Cylindrical Roller Slewing Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 1800 mm bore. For the 2207 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Quality starts with raw material selection: CHG Bearing crafts 131.32.2000.03 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
