500KDH720HK 720 mm 500 mm Frequently Asked Questions about 500KDH720HK Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 500KDH720HK 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 (500 mm bore side) ensures perfect planar contact without edge binding.
To ensure optimum performance of CHG Bearing 500KDH720HK Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 500 mm bore. For the 720 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies 500KDH720HK with a precision bore diameter (d) of 500 mm, an outside diameter (D) of 720 mm, and a nominal ring width (B) of 185 mm. This configuration yields an effective cross-sectional wall thickness of 110.0 mm and an envelope ratio (D/d) of 1.44, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 500KDH720HK 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.
