In the design of imperfect liquid lubricated sliding bearings, what should be done to check the bearings?

PV is the product of a certain bearing and bearing in line speed conditions and the PV value is inversely proportional to the service life of the bearing;

PV is the product of a certain bearing and bearing in line speed conditions and the PV value is inversely proportional to the service life of the bearing; therefore recommended design make use of safe PV low value, to ensure that the bearing will have longer service life;
