Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing N3072 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (360 mm x 540 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing N3072 Single Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF N3072, FAG N3072, NSK N3072. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Model N3072 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 360 mm) and steep thermal gradients between inner and outer rings.
As standard production, CHG Bearing subjects N3072 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.
