technical data 1 introduction the methods equations and technical data presented in this section should be sufficient to select the correct bearings and estimate their performance for a wide range of applications for applications with severe or unusual operating conditions rbc is prepared to provide an in-depth analysis and recommend the most suitable bearing arrangement where standard bearings cannot be used rbc can meet the application requirements with a special bearing design specifically tailored for optimum performance 2 capacity and fatigue life of roller bearings dynamic capacity c [lbf,n or basic load rating for a roller bearing is that calculated constant radial load which a group of apparently identical bearings with a stationary outer ring can theoretically endure for a fatigue life of 106 revolutions of the inner ring static capacity co [lbf,n or static load rating is that uniformly distributed static radial load which produces a maximum theoretical contact stress of

if the bearing is subject to repeated shock or impact loads the equivalent load pe or its individual components should be multiplied by a suitable shock load factor the product of load and shock load factor should not exceed the bearing static capacity to prevent brinelling of raceways and rollers loading uniform and constant variable and light shock vibration and moderate shock heavy and severe shock shock load factor 1.00 1.50 2.00 3.00 table 3 load modification factors 4 limiting speed the limiting speed values in the dimensional tables apply to bearings lubricated with oil of proper viscosity operating under low to medium load poor cooling conditions bearing misalignment and improper diametral bearing clearance will cause the bearing to heat up and reduce the maximum permissible speed grease lubricated bearings should not exceed 65 of the values given in the tables the maximum speed of bearings with contacting lip seals is generally limited to a lip surface speed of 1000 ft/min 5 s
