A bearing unit () for measuring forces exerted on the bearing unit, comprising an inner member () concentrically arranged around an outer member (), at least one rolling element bearing () and at least one load measuring device () with a cylindrical bore. The load measuring device () is mounted to one of the members () and supports the rolling element bearing () relatively to this member (). The rolling element bearing () is mounted to the other of the members () and supports this member () relatively to the load measuring device (). Thus, a force acting on the bearing unit is transferred from one of the inner and outer members () to the other of the inner and outer members () via the at least one load measuring device (). According to the invention, the at least one load measuring device () and the at least one rolling element bearing () are arranged laterally to each other in a radial gap between the inner and outer members ().

Load-measuring bearing unit

A bearing and shaft assembly comprises a shaft and at least one bearing, and is provided with at least one strain sensor. An elastic component is provided between the shaft and the at least one bearing, and the elastic component comprises the at least one strain sensor. In one disclosed embodiment, the elastic component forms an integral part with one of the bearing and the shaft.

Bearing assembly with a strain sensor

Measurement device () for measuring the axial and/or radial load on a bearing () comprising an inner ring (), an outer ring () and a plurality of rolling elements () between the inner and outer ring. The measurement device () comprises a sensor ring () which may be positioned adjacent to and in close contact with the inner ring () or outer ring () of the bearing (), the sensor ring () having at least one weakening () at its circumference and at least one sensor () being positioned in the at least one weakening ().
