Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing NU1028/P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (140 mm x 210 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Each NU1028/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 (140 mm bore side) ensures perfect planar contact without edge binding.
