Any deviation from nominal housing bore diameter will change the working boreT, an equal amount. Minimum recommended housing bores are 2.9980 for XR-32-OPN and 4.4975 for XR-48-OPN.(2)Retention hole does not go through bearing retainer.(3)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.(4)Contact factory for availability.Load on most heavily loaded bearing (lbf)20000100001000500XR-48-OPNXR-32-OPN1 10 100 1000Required Travel Life (millions of inches)Determining Ball Bushing Bearing SizeTo determine the proper Ball Bushing bearing sizeenter the chart with the maximum load of the mostheavily loaded bearing and the required travel life.Mark where the two lines intersect.
