A bearing cover assembly configured to assemble to a bearing housing in which a rolling element bearing is accommodated. The bearing housing assembly includes an end cap with a sleeve portion that mates to an interior conical surface of the bearing housing with a complementary outer bevel formed on the sleeve portion.

A holder support part, into which a holder main body part constituting a sensor holder is fitted, is provided to an upper position of two vertically adjacent positions of an axially inboard-side surface of a bottom plate part so as to project. A nut holding part, which holds a nut, into which is threaded a bolt for joining a sensor holder, is provided to a lower position of the two vertically adjacent positions. The holder support part and the nut holding part are apart from each other. The holder support part is configured as a notched cylinder shape having a discontinuous part at a lower part. An upper surface of the nut holding part is configured as a convex curved surface of which a part facing the discontinuous part is positioned at the uppermost part.

In a wheel hub unit a sealing assembly inserted between a stationary outer ring and a rotating inner ring of a rolling bearing includes a first screen coupled with the outer ring, an elastomeric annular element attached to the first screen, and a second screen faces the first screen and coupled with the inner ring, the second screen having a flange portion with a radially outer edge facing a sleeve portion of the first screen, the first screen having a non-contacting annular lip with a free end substantially flush in a radial direction with the radially outer annular edge, the free end cooperating with the radially outer edge to form a labyrinth seal.

A lubrication system for a pitch bearing of a wind turbine includes a lubricant for lubricating contact surfaces between an outer race, an inner race, and a plurality of rolling elements of the pitch bearing. Further, the lubrication system includes a lubricant inlet formed into a first side of the inner race and an inlet seal for sealing the lubricant inlet so as to prevent the lubricant from leaking from the lubricant inlet. Moreover, the lubrication system includes a lubricant outlet formed into an opposing, second side of the inner race and a lubricant collection container arranged adjacent to and in fluid communication with the lubricant outlet and mounted to the inner race. Thus, during operation of the wind turbine, at least one of a slope of the pitch bearing, gravity, and a centrifugal effect cause the lubricant to flow throughout the pitch bearing to lubricate the contact surfaces without exiting a closed volume defined by the inlet seal(s) and the lubricant collection container(s).

A cover assembly includes a ring. The ring has a bore with an eccentric inner geometry. The cover assembly includes a cap. The cap has an eccentric outer geometry. The cap is configured to fit within the bore of the ring. In a concentric position, the eccentric outer geometry of the cap and the eccentric inner geometry of the ring are configured to be offset. In an eccentric position, the eccentric outer geometry of the cap is configured to force the eccentric inner geometry of the ring outward.

A wheel hub bearing for motor vehicles including a rotatable hub provided with a flange for the engagement of the hub to a wheel of a vehicle and provided with a radially outer free portion and a bearing unit provided with a radially outer ring for the engagement of the wheel hub bearing to a knuckle of the vehicle and a radially inner rotatable ring angularly connected to the hub. Furthermore, the wheel hub bearing has a device for detecting a vehicle parameter and provided with an encoder and a sensor in communication with the encoder. The encoder is ridgidly coupled to the radially outer free portion of the flange to jointly rotate with the hub.

A spherical plain bearing includes an outer ring and an inner ring that are each coaxial with a longitudinal axis of the bearing. The outer ring has a first axial outer ring end, a second axial outer ring end, and an interior spherical concave bearing surface extending therebetween. The inner ring has a first axial inner ring end, a second axial inner ring end, and an interior cylindrical bearing surface defining a bore and an exterior spherical convex bearing surface extending therebetween. The exterior spherical convex bearing surface is in interfacial sliding engagement with the interior spherical concave bearing surface. A plurality of circumferential lubrication grooves and one or more curved lubrication channels are in the exterior spherical convex bearing surface. The curved lubrication channels are positioned to intersect each of the circumferential lubrication grooves. A plurality of profiled annular lubrication grooves circumferentially extend into the interior cylindrical bearing surface.

A split bearing protector with a flexible design that adds improved moisture protection to a bearing and can be installed without removing the bearing from the machine in which it is installed.
