This standard specifies the basic requirements for the application of barrier coatings to anti-friction bearings for the purpose of preventing lubricant loss by surface migration and spreading during storage and in service.
This specification covers antifriction self-aligning rod and roller bearings operating in the temperature range of -67° to +300°F (-55° to +149°C) and intermittent spikes to 350°F (177°C).
This specification covers sealed, self-aligning, anti-friction, rod end roller bearings operating in the temperature range of −65 to +300 °F (−54 to +149 °C) and intermittent spikes to 350 °F (177 °C).
