The two interacting surfaces of the shaft and the barrel 20 can be seen directly. To dismantle the bearing and dismantle the bearing unit, remove the fastening bolt 17 see below Sleeve 15 can be rotated ^, which eases the tension. Thereafter, the attachment ring 14 with the sleeve 15 and the adjusting ring 16 can be lifted off. In this way the pressure ring 13 is without prints.

The inner race is fixed by a threaded ring 61, which is held in place by a locking washer 62, so that the ring 61 is loosened and the washer 62 enables the supply of bridging oil to remove the conical sleeve from the inner race
