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.

One embodiment of the present invention provides a ball bearing roller assembly comprising an inner ring having an insertion hole into which a protrusion of a storage body is inserted; an outer ring having a hollow through which the inner ring is inserted, and provided outside the inner ring, at least one ball bearing provide between the inner ring and the outer ring, and in rolling contact with the inner ring and the outer ring; a cover inserted and coupled to a space between the inner ring and the outer ring, and fixing the ball bearing to the outer circumferential surface of the inner ring and the inner circumferential surface of the outer ring and a detachable coupling portion formed to extend from one end portion of the inner ring, and having an insertion space portion into which a vertical wire of the storage body is inserted.

Provided is a motor including: a rotor, a stator, a first and second bearing, a support member, a housing including a first flat part and a cylindrical part, and a bearing holder. The cylindrical part includes: a first inner circumferential surface inside which is provided the stator; a second inner circumferential surface, a distance from the second inner circumferential surface to a central axis being greater than a distance from the first inner circumferential surface to the central axis, and the second inner circumferential surface contacting an outer circumferential surface of the bearing holder; and a stepped surface, connecting the first and the second inner circumferential surfaces, and contacting a lower surface of the bearing holder. The housing further includes a riveting part located on the second inner circumferential surface of the cylindrical part and fixing the bearing holder to the second inner circumferential surface of the cylindrical part.

A track roller assembly includes a wheel body, a bearing, a wheel axle, a cap element, a rotating oil seal, an end cover and an oil body. The wheel body has a thread. The bearing is disposed on the wheel body. The wheel axle is disposed through the bearing. The cap element has a screw corresponding to the thread. One side of the rotating oil seal is connected to the cap element, and another side of the rotating oil seal rotatably abuts the wheel axle. The end cover is connected to the wheel axle. The oil body is limited to an accommodating space formed by the wheel body, the wheel axle, the cap element and the rotating oil seal.

A wheel bearing outer ring with a plurality of fastening elements are configured to be fixed to the wheel bearing outer ring to a knuckle of a car are arranged at a radial outer side of the wheel bearing outer ring. A view of the wheel bearing outer ring with a line of vision being a central axis of the wheel bearing outer ring at least one angle between a first one of the fastening elements and a second one of the fastening elements, which are neighbouring with respect to the circumferential direction of the wheel bearing outer ring, differs from an angle between a third one of the fastening elements and one of the fastening elements, which is neighbouring to the third one of the fastening elements with respect to the circumferential direction. All the angles are measured with respect to the central axis and in the circumferential direction.

The invention relates to a threaded bearing housing and a side channel blower incorporating the same wherein the threaded bearing housing is installed on the outer casing element of the side channel blower. The bearing housing supports the outer ring of the blower's bearing. The bearing housing location is adjustable radially and along the axial axis of the side channel blower. These adjustments provide a variable positioning of the rotating components of the side channel blower. This adjustment reduces the necessary assembly tolerancing and allows the impeller's blade and the channel between the casing elements in which it rotates to be properly spaced apart for easy and facile installation and efficient operation.
