ACCURACY The accuracies of the SR stroke bush are stated in the dimensional tables. Since the outer cylinder deforms due to tension from the retaining ring, the dimension of the outer cylinder is an average value at points P, where calculated using the following equation: W = 4+ L 8 W : the distance from the end of the outer race to measurement point P L : the length of the outer race FIT The inner contact diameters of the SR stroke bush are listed in the dimensional tables. The shaft diameter tolerance should be selected to achieve the desired amount of radial clearance. High-speed linear motion can cause the retainer to slip due to inertial force. An interference fit of 3 to 10 m RATED LOAD AND RATED LIFE The relationship between the rated load and life of the stroke bush is expressed as follows: 3 C L = P L : the rated life (10 6 rotations), C : the basic dynamic rated load (N) P : load (N) For rotation/stroke combined motion 10 L Lh = 60(dmn) 2 +(10Sn1) 2 6 dm The allowable speed for combined rotation and stroke motion is obtained from the following equation: F-3 Figure F-2 Outer Cylinder Measurement Points will compensate for such slip. The fits generally used between the shaft and the housing are listed in the table below.
