Normally the bearing house shall have a tolerance of H7. In this case, a bearing pressed in to thehouse will have a tolerance of H9. Before it is pressed in to place, the bearing may have an openslit, which does not have any importance when the bearing is assembled in the seat. The tight fitis not just caused by the slit, rather, precisely as for turned bearings, rolled slide bearings are overdimensioned. When the bearing is pressed in to the seat, the slit is pressed closed. The bearingadjusts to the seat and takes its final form. Normally the bearing’s locking does not need securingin another way.
The bearing housing should have a chamferbetween 15° and 45° (45° for flanged bearings)for simpler assembly. When using flangedbearings the chamfer on the lager housingmust pass the radius between the bearing andflange.
The radius R shall correspond to the wall thickness,but must be at least 2 mm. If the housing’schamfer is too small, the bearing’s flange deformswhen it is pressed in to the seat in such away that inner diameter of the bearing becomestoo small. It is then not possible to drive theshaft in the bearing. See the figure below.
Many of our slide bearings are designed for use in the most demanding environments. However,some thought must be given when a bearing is to be used in environments where there are veryaggressive chemicals.
