D104 l 1 1 3 d H5 js4 d * 2051.32. GUIDE BUSH, SINTERED FERRITE CARBONITRIDED WITH LONG-TERM LUBRICATION, ISO 9448-2 Material: Sintered ferrite of high purity, carbonitrided, long-term lubrication Execution: Running surfaces and mounting diameter precision ground. Oil groove(s) not until diameter d1 = 15 mm. 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. Note: Notes on sliding type guides at the beginning of chapter D. *Bearing clearance see pairing classification at the beginning of chapter D. Matching guide combinations, see selection matrix at the beginning of chapter D. Assembly guide lines / Dimensional requirements and tolerances at the end of chapter D.
