N252/P5 480 mm 260 mm 420 mm 80 mm Frequently Asked Questions about N252/P5 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing N252/P5 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
To safeguard CHG Bearing N252/P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (260 mm x 480 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Beyond standard alloy steel, CHG Bearing can customize the N252/P5 Single Row Cylindrical Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Engineered according to international ISO boundary plans, CHG Bearing supplies N252/P5 with a precision bore diameter (d) of 260 mm, an outside diameter (D) of 480 mm, and a nominal ring width (B) of 80 mm. This configuration yields an effective cross-sectional wall thickness of 110.0 mm and an envelope ratio (D/d) of 1.85, delivering compact rigidity for OEM machinery housings.
