Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 32*52 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit ( mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 32*52 with a precision bore diameter (d) of mm, an outside diameter (D) of mm, and a nominal ring width (B) of mm. This configuration yields an effective cross-sectional wall thickness of 0 mm and an envelope ratio (D/d) of 0, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 32*52 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces ( mm x mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Quality starts with raw material selection: CHG Bearing crafts 32*52 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.
