Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing NU18/880/P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (880 mm x 950 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing NU18/880/P5 Single Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NU18/880/P5, FAG NU18/880/P5, NSK NU18/880/P5. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
The Open Type engineered for NU18/880/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.
As standard production, CHG Bearing subjects NU18/880/P5 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.
