D108 1 d 3 d H6 m5 1 d 2 l l * 206.49. GUIDE BUSH FOR BALL BEARING, AFNOR 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 H6. 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.
