Ensure that the environment is clean. Check the dimensional and form accuracy of the shaft seating. 2. Check that the surface roughness of the support surface R a ≤ 12,5 µm. The flatness (planicity) tolerance should be to IT7. For moderate demands IT8 may be satisfactory. 3. If the bearing is mounted on an adapter sleeve, determine the position of the housing. The grease nipple arranged at one side of the housing cap (for improved lubrication) should be at the side opposite to the sleeve nut. Where housings are mounted at shaft ends, grease should be applied at the end cover side. It is necessary to consider the complete housing as the base and cap will only fit together as supplied. 4. Position the housing on the support surface. Fit the attachment bolts but do not tighten them. 5. Arrange the one V-ring with sealing washer on the shaft. The V-ring should be furthest away from the bearing and seal against the washer, i.e. the lip should point inwards towards the washer. 8. Lay the shaft with bearing and sealing washers in the housing base. 9. Put one locating ring (when needed) at each side of the bearing. NB. Locating rings are only used for locating bearing arrangements, except for CARB bearings which, although always non-locating, must always be mounted with locating rings. 10. Carefully align the housing base. Vertical markings at the middle of the side faces and ends of the housing base can facilitate this. Then lightly tighten the attachment bolts. 11. The housing cap should be placed over the base and the cap bolts (to join cap and base) tightened to the torque specified in table 2 on page 48. The cap and base of one housing are not interchangeable with those of other housings. The cap and base should be checked to see that they bear the same identification. 12. Fully tighten the attachment bolts in the housing base. Recommended tightening torques are given in table 2 on page 48. 13. Coat the V-ring counterfaces on the sealing washers with grease. 14. Finally, push the V-ring seals into their correct position. This can be done using a screwdriver at the same time as the shaft is turned. 6. Mount the bearing on the shaft – either directly on a stepped shaft or using an adapter sleeve. Completely fill the bearing with grease. The remainder of the recommended grease quantity should be put in the housing base at the sides (➔ table 1 , page 28). 7. Arrange the second sealing washer and V-ring on the shaft at the other side of the bearing. If the housing is to be used at the end of a shaft, mount an end cover instead. 36 www.bergab.ru Берг АБ bergab@ya.ru Тел. (495)-228-06-21, факс (495) 223-3071
