Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing NN3088/P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (440 mm x 650 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The Open Type engineered for NN3088/P5 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
