8 Self-Lube® bearing inserts The Self-Lube® bearing insert, commonly known as a wide inner ring bearing, is designed to suit the wide range of housings offered by NSK in the Self-Lube® bearing family and is also suitable for applications where the user’s own housing is preferred. They are basically deep-groove ball bearings, to the popular 6200 series configuration, with integral design features making them more functional and versatile than standard ball bearings. The radial internal clearance is C3 for standard bearing inserts and bearings can be offered with either parallel or spherical...

SELF-LUBE® BEARINGS 9 Bearing load ratings and endurance Basic dynamic radial load rating Cr This is defined as the load that can be applied to the bearing to give a basic L10 rating life of one million revolutions. This is the life associated with 90% reliability which has been found by experience to be acceptable for normal engineering bearing applications. The majority of the bearings attain a much longer life and the median life is approximately five times the L10 life. Ratings for each series are given in the bearing tables and are used to calculate life for radial loads of constant...

10 Cor Pr Pr nx60 Examples of bearing calculations Example 1 What nominal life can be obtained from NP55 with a steady radial load Fr = 3900N at speed of 1500 rev/min? The dynamic load rating Cr of the unit from page 25 is 43500N. Since the bearing is not subject to axial load the equivalent load Pr = Fr according to the formula on page 7. Therefore applying the service factor of 1.2 for a steady load. Pr = Fr • 1.2 = 3900 • 1.2 = 4680N. From page 7, L10 life in hours = ( Cr )3 • 106 = ( 43500 )3 • 106 = 8923 hours Alternatively, using the loading ratio tables on page 9 an approximate life...
