Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing HM262749D/710/710DG2P5 Four-Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HM262749D/710/710DG2P5, FAG HM262749D/710/710DG2P5, NSK HM262749D/710/710DG2P5. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Model HM262749D/710/710DG2P5 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 346.075 mm) and steep thermal gradients between inner and outer rings.
For international ocean and air freight, CHG Bearing packs HM262749D/710/710DG2P5 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
To safeguard CHG Bearing HM262749D/710/710DG2P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (346.075 mm x 488.95 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
