D107 2061.44. 1 d 3 d H5 js4 1 d 2 l l * GUIDE BUSH FOR BALL BEARING, ISO 9448-3 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.
