Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing HM265049DGW/010/010D Four-Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HM265049DGW/010/010D, FAG HM265049DGW/010/010D, NSK HM265049DGW/010/010D. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Yes, 100% of HM265049DGW/010/010D Four-Row Tapered Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Model HM265049DGW/010/010D is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 368.3 mm) and steep thermal gradients between inner and outer rings.
As standard production, CHG Bearing subjects HM265049DGW/010/010D 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.
