NU3221/P5 190 mm 105 mm 65.1 mm 126.8 mm Frequently Asked Questions about NU3221/P5 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each NU3221/P5 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 (105 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing NU3221/P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (105 mm x 190 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
