A cover for a bearing housing, in particular intended to be mounted on machinery for the food industry, provided with an end wall transverse to an axis of the bearing housing; with an annular side wall which extends transversely with respect to the end wall; and with an engaging portion towards the bearing housing, which is formed on one end of the side wall opposite to the end wall; a through-opening being formed through the end wall so as to allow the passage of a moving shaft, preferably a rotating shaft, and being surrounded by a reinforcing ring rigidly joined to and integral with the end wall so as to support a sealing element mounted on the through-opening and sealingly engaged by the moving shaft.

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.

A sensor cap exchange tool device may include a support bolt; a support bracket that is fixed to a front end portion of the support bolt; a mover that has a second screw thread that is engaged with the first screw thread at of the support bracket; a tool guide that is rotatably engaged with the mover and that moves in the predetermined direction together with the mover according to a rotation of the mover and that has a tool insertion opening open in the predetermined direction; and a separation device and mounting device that are mounted in the tool guide and that moves with the tool guide according to a rotation of the mover and that comes in close contact with the sensor cap that is mounted in the wheel bearing assembly.

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 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.

The disclosure relates to an X-ray tube, comprising a cathode and an anode, the cathode and anode being accommodated in a housing which provides a vacuum environment.

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 wheel hub assembly assembly having a central axis (X) and covers therefore. An outer ring provided with a tubular mounting portion, and a cover having a keying portion which is inserted inside the tubular mounting portion. The cover is made of plastic material, the keying portion comprises an annular seat made of plastic and a sealing element made of rubbery elastic material. The sealing element is defined by a solid of rotation mounted inside the annular seat over a whole of an axial length of the annular seat so as to project radially outside of the annular seat to make contact with the tubular mounting portion of the outer ring thereby sealingly closing the wheel hub assembly.

A sealing device for a wheel hub unit configured to form a static seal to protect the wheel hub unit from environmental contaminants. The sealing device including a shield that is coupled to a collar of the wheel hub unit. The sealing device having a cylindrical lateral mounting wall pressed into the collar, an annular seat with a blind end formed in the cylindrical lateral wall, and a sealing gasket positioned, inside the seat and compressed radially between the groove and the collar, and formed by a sealing compound to allow the formation of a bead against the cylindrical lateral wall in a transport and/or assembly configuration of the sealing device. The bead being movable into the seat by a scraping action exerted by the collar during the assembly of the shield.
