Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing HM261049D/HM261010/HM261010D Four-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.
Absolutely. The CHG Bearing HM261049D/HM261010/HM261010D Four-Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HM261049D/HM261010/HM261010D, FAG HM261049D/HM261010/HM261010D, NSK HM261049D/HM261010/HM261010D. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Quality starts with raw material selection: CHG Bearing crafts HM261049D/HM261010/HM261010D 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.
As standard production, CHG Bearing subjects HM261049D/HM261010/HM261010D to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
