At least first and second tapered grooves are formed on the second ring and are oriented towards the first ring. The bearing further provides at least one first distance sensor mounted on the first ring and facing a tapered wall of the first tapered groove of the second ring, and at least one second distance sensor mounted on the first ring and facing a tapered wall of the second tapered groove of the second ring, the tapered walls of the first and second grooves extending obliquely along two opposite directions.

A method of mounting a bearing to an air compressor including a shaft element having a first end and a second is disclosed, which includes the steps of: fixing the second end of the shaft element to a center of a gear; inserting the first end of the shaft element through a central hole of a bearing to have an annular step of the shaft element abutted an inner ring of the bearing; and hitting the first end of the shaft element by a striking tool to form an expanded or flared edge on a top face of the first end of the shaft element. With the method, the bearing can be firmly fixed between the expanded or flared edge and the annular step of the shaft element.

A method for constructing an active magnetic bearing controller based on a look-up table method includes: building finite element models of an active magnetic bearing to obtain two universal Kriging prediction models in X-axis and Y-axis directions about actual suspension forces being in association with actual displacement eccentricities and actual control currents in the X-axis and Y-axis directions of the active magnetic bearing based on a universal Kriging model; creating two model state tables in the X-axis and Y-axis directions about the actual suspension forces being in association with the actual displacement eccentricities and the actual control currents to construct two look-up table modules with the two built-in model state tables, respectively; and constructing an active magnetic bearing controller by using two fuzzy adaptive PID controllers, two amplifier modules in the X-axis and Y-axis directions, the two look-up table modules, and two measurement modules in the X-axis and Y-axis directions.

A chassis component for a wheel suspension, having a strut arrangement with at least one strut which has a profile with an open cross-section. The at least one strut has a profile base and two wall sections which extend away from the base. An end of the strut has an articulation point that receives a first joint component having a spherical joint body and a second joint component which holds the joint body so as to rotate and/or pivot. A first joint accommodation aperture and a second joint accommodation aperture are arranged, in the area of the articulation point, opposite one another. The joint body is positioned via a circular-segment-shaped fastening element arranged on the joint body between the joint accommodation apertures. The joint accommodation apertures and the joint body positioned between them are integrated in a joint housing produced by overmolding, which forms the second joint component.
