Rolling bearing arrangements are disclosed. The bearing may include an outer ring, an inner ring, and a strain sensor device having an annular main body. The strain sensor device may be connected to the outer ring and configured to measure axial loads acting on the rolling bearing. A circle segment-shaped force introduction element may extend in a circumferential direction and connect to the annular main body via a web-shaped coupling element. The strain sensor device may have, on an outer end facing away from the rolling bearing, a recess for accommodating a strain sensor. The recess may extend over the force introduction element at least in the circumferential direction and the coupling element may have a smaller extent in a radial direction than the recess.

Rolling bearing arrangement having a strain sensor device

The invention relates to a rotary-table bearing assembly, including: a rotary-table bearing, which has an inner ring, an outer ring, and rolling elements arranged in one or more rows, which roll on the inner ring and on the outer ring; and in each case an assembly component having a clamping segment, to which assembly components the outer ring and the inner ring are connected. According to the invention, the clamping segment of at least one assembly component is designed radially elastic on the assembly component, and/or the outer ring and/or the inner ring has a radially elastic connecting segment, by which the particular ring is connected to the assembly component.

Rotary-table bearing assembly

The invention concerns a rolling bearing (') with a one-piece outer bearing ring () and a one-piece inner bearing ring (), and with rolling elements () arranged in at least one row between the bearing rings (). Provision is made in this rolling bearing that the outer bearing ring () and/or the inner bearing ring () has, on the axial end face, at least one cutout () through which the rolling elements () can be placed into the space between the bearing rings (), that the cutout () can be covered with a reversibly attachable cap (), and that the cap () forms a rim () for guiding the rolling elements (). The lateral cutout () for filling the rolling bearing () with rolling bodies permits cage solutions of segmented or strip design that are larger than a rolling element and hence can accommodate multiple rolling elements. The suitability of the rolling bearing for high rotational speeds and the stiffness of the rolling bearing are increased as a result.
