HM262749D/HM262710 488.95 mm 346.075 mm Frequently Asked Questions about HM262749D/HM262710 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing HM262749D/HM262710 Double Row Tapered Roller 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.
Quality starts with raw material selection: CHG Bearing crafts HM262749D/HM262710 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.
Each HM262749D/HM262710 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 (346.075 mm bore side) ensures perfect planar contact without edge binding.
Absolutely. The CHG Bearing HM262749D/HM262710 Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HM262749D/HM262710, FAG HM262749D/HM262710, NSK HM262749D/HM262710.
