Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 802245P5 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 802245P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (300 mm x 460 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 802245P5 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
Engineered according to international ISO boundary plans, CHG Bearing supplies 802245P5 with a precision bore diameter (d) of 300 mm, an outside diameter (D) of 460 mm, and a nominal ring width (B) of 390 mm. This configuration yields an effective cross-sectional wall thickness of 80.0 mm and an envelope ratio (D/d) of 1.53, delivering compact rigidity for OEM machinery housings.
