Bearing element e.g. rotational roller bearing, for bearing deflecting roller for paper web, has recess provided in rolling element, where recess is continuous along rolling element rotating axis and tapers towards center region of element

摘要

The element (2) has two bearing components (12, 14) movably supported with each other by rolling elements (21) e.g. barrel shaped or cylindrical rolling elements. A material recess (26) is provided in a shape of a double cone in the rolling element (21), where the recess is continuous along a rolling element rotating axis (22) and tapers towards a center region (30) of the rolling element. Bearing rings (16, 18) comprise hollow spherical bearing surfaces (24), and the rolling elements are guided between the bearing rings.
