sleeve 38 these recesses are open toward internal end surface 49 and are closed on the end facing away from the surface by a boundary wall extending as far as seating surface 39 fig7 to hold the material of journal 42 which has backed up in recesses 52 a narrow ring shaped intermediate space 19 is formed between stepped sleeve 38 and fillet surface 7 all recesses 52 are designed to open out axially into this intermediate space 19 stepped sleeve 38 also has radial through holes 53 each of which opens outs in the base of one of recesses 52 when bearing ring 35 is pressed axially onto lateral surface 41 the internal end surface 49 of bearing ring 35 comes to rest against contact shoulder 48 as this happens material is scraped off the journal 42 by the sharp edges 17 of the boundary wall and pushed into the intermediate space 19 between bearing ring 35 and fillet surface 7 some of the material arrives in holes 53 and is then pushed through these holes 53 and grips recesses 14 in inner ring 40 of the internal conical roller bearing of the swivel mount at the same time some of the material is pushed into blind holes 50 in fillet surface 7 of journal 42 accordingly after bearing ring 35 has been pushed on inner ring 40 of the internal conical roller bearing and stepped sleeve 38 are held in a torsion proof manner on journal 42 inner ring 40 of the external conical roller.
