Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Double-sided Sealed), CHG Bearing pre-charges HCRBH14025A with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Each HCRBH14025A 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 (140 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies HCRBH14025A with a precision bore diameter (d) of 140 mm, an outside diameter (D) of 200 mm, and a nominal ring width (B) of 25 mm. This configuration yields an effective cross-sectional wall thickness of 30.0 mm and an envelope ratio (D/d) of 1.43, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts HCRBH14025A 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.
