Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 381068P5 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 381068P5 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (340 mm x 520 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
