NN3032K/W33 240 mm 160 mm 60 mm 219 mm Frequently Asked Questions about NN3032K/W33 Double Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model NN3032K/W33 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 160 mm) and steep thermal gradients between inner and outer rings.
Beyond standard alloy steel, CHG Bearing can customize the NN3032K/W33 Double Row Cylindrical Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
As standard production, CHG Bearing subjects NN3032K/W33 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.
To safeguard CHG Bearing NN3032K/W33 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (160 mm x 240 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
