N3220 180 mm 100 mm 1160 mm 60.3 mm Frequently Asked Questions about N3220 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts N3220 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.
To safeguard CHG Bearing N3220 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (100 mm x 180 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing N3220 Single Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF N3220, FAG N3220, NSK N3220. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each N3220 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (100 mm bore side) ensures perfect planar contact without edge binding.
