If used with class L 60 Case LinearRace the fit-up values would be .0022P/.0002P for the 2 inch size and.0029P/.0003P for the 3 inch size.(2)The Dynamic Load Capacity is based on a rated travel life of 2 million inches. The actual Dynamic Load Capacity can be affected by theorientation of the bearing or the direction of the applied load. For dynamic load correction factors see polar graphs opposite.(3)Contact factory for availability.Load/Life Graph (Lines indicate limiting load for given <strong>Ball</strong> <strong>Bushing</strong> bearing)1 ⁄2-133 ⁄4-10Dynamic (2)LoadCapacitylb f450010000Load on most heavily loaded bearing (lbf)100001000500XPBO-48-OPNXPBO-32-OPN1 10 100 1000Required Travel Life (millions of inches)Determining <strong>Ball</strong> <strong>Bushing</strong> <strong>Bearing</strong> SizeTo determine the proper <strong>Ball</strong> <strong>Bushing</strong> bearing sizeenter the chart with the maximum load of the mostheavily loaded bearing and the required travel life.Mark where the two lines intersect.
