HM237549TD/HM237510 288.925 mm 180.975 mm Frequently Asked Questions about HM237549TD/HM237510 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each HM237549TD/HM237510 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 (180.975 mm bore side) ensures perfect planar contact without edge binding.
Quality starts with raw material selection: CHG Bearing crafts HM237549TD/HM237510 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.
To safeguard CHG Bearing HM237549TD/HM237510 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (180.975 mm x 288.925 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
