D109 GUIDE BUSH FOR BALL BEARING, WITH STROKE LIMITATION 2 l 2 1 l *d 3 d H5 1 d 2 js4 2061.47. (l) stroke Material: Tool steel, hardened 62 ± 2 HRC Execution: Bearing surfaces honed, outside diameter precision ground. Slip-Fit Bonding: The position of the bearing is given by push fit holes tolerance H5. The adhesive (order no. 281.648) provides optimum push retention whilst offering the following advantages: - high accuracy and stiffness - no problems to find position when changing bushings We do not recommend to press fit for the same reasons mentioned above.
