SKF ConCentra Y-bearings
When mounting SKF ConCentra Y-bearings, position the collar so that one grub screw is directly opposite the slit in the sleeve.
CAUTION:Do not tighten the grub (set) screws until the bearing is positioned on the shaft. If the screws are tightened prematurely, the stepped sleeve may deform. No attempt should be made to remove the sleeve and the mounting collar from the bearing prior to mounting.
To dismount SKF ConCentra Y-bearings loosen the grub screws first. Then gently tap the edge of the sleeve on the collar side, or the inner ring side face on the opposite side to loosen the lock (fig. 1).
