Aerospace Applications for PFPE Lubricants > ENGINEERING.c

The SKF R0F+ bearing grease life testing method involves running five groups of two bearings. Various different bearing types and sizes can be used at speeds between 5,000 and 25,000 rpm and from room temperature up to a maximum of 230°C. The pneumatic loads on these bearings can be set between 50 - 900 N radially and 100 – 1100 N axially.
