25、zontal. In order to accommodate displacements parallel to the roller axisroller bearings can be combined with sliding elements in accordance with EN 1337-2. To permit rotation about theaxis perpendicular to the roller axis or about both axes, as for multiple roller bearings, the roller bearings can
26、becombined with bearings from other parts of EN 1337.This part of EN 1337 does not apply to roller bearings made with materials other than those specified in clause 5.Bearings which are subjected to rotation greater than 0,05 rad resulting from the characteristic combination ofactions are outside th
