Abstract: A tubular bushing co-moldable with tubs of washing machines is provided. The tubular bushing is suitable to be engaged by a drive shaft of the washing machine extending along a central axis (A) and being provided with two rolling bearings (20), arranged at a given distance from each other along the axis (A) to allow rotation of the drive shaft with respect to the tub, and a containing sleeve, made of plastic and by means of co-molding around the two bearings; a current dispersion means being incorporated in the containing sleeve and suitable to be electrically connected both to the drive shaft and to earth so as to prevent an accumulation of static electricity in the washing machine and prevent electrostatic discharges.

Abstract: A tubular bushing that is co-moldable with tubs of washing machines, the tubular bushing is engaged by a drive shaft of the washing machine, that extends along a central axis (A) and is provided with two rolling bearings, arranged at a given distance from each other along the axis (A) to rotatably support the drive shaft of the washing machine with respect to the tub. The tubular bushing further provides a containing sleeve, made of plastic material and co-molded around the two bearings; the sleeve defining an axial communication duct between two sides of the tubular bushing, the duct being closed, at least during co-molding, by a disposable cap, engaged in an annular edge of the containing sleeve.

Abstract: A tubular bushing co-moldable with tubs of washing machines is provided. The tubular bushing is located between a humid side and a dry side of the washing machine, crossed by a drive shaft extending along a central axis (A) and provided with two rolling bearings arranged along the axis (A); a spacer interposed between the two bearings; a sealing element arranged axially alongside a first bearing close to the humid side; and a containing sleeve which is co-molded around the two bearings and the spacer; the sealing element and the first bearing bound and axially enclose an annular chamber, which is further closed in the radial direction by the drive shaft and is in fluid connection with the external environment by means of two ducts extending directly through the containing sleeve, eliminating any pressure and/or temperature gradient between the annular chamber and the external environment.

Abstract: A cage for a ball bearing unit comprises two half-cages (51, 52) which are connected to each other and are symmetrical about a mid-plane (P) of the bearing. Each half-cage has an annular body (53) providing two concentric and circumferentially continuous radial ridges (56, 57) extending radially in opposite directions, of which the first ridge (56) extends in a radially outward direction for sealingly engaging a groove (25) formed in the outer ring of the bearing unit, and the second ridge (57) extends in a radially inward direction for sealingly engaging a groove (35) formed in the inner ring of the bearing unit.

Abstract: A retaining cage for the rolling elements of a rolling-contact bearing, having an annular body featuring seven pockets capable of restraining seven respective rolling elements of a rolling-contact bearing, the rolling elements being spaced apart around a center (O) of the cage, the pockets being spaced from one another according to the following values of angular spacing between two consecutive pockets: 48.3°; 48.5°; 51.2°; 51.8°; 53°; 53.5°; 53.7°.

Abstract: A device including an annular groove obtained on a lateral assembly surface of a ring of a bearing in contact in use with a seat with respect to which the ring must remain stationary; a first element shaped as a circumferentially open ring and preferably defined by a circumferential ring segment having a non-constant radial thickness (S) and always smaller than a radial depth (P) of the annular groove, mounted within the annular groove free to move circumferentially in the annular groove; and a second element, shaped as a closed ring, which engages the annular groove, within which it is mounted radially superimposed on the first element on the side of the lateral assembly surface and having a constant radial thickness (F) such that the second element protrudes radially and overhangingly with respect to the lateral assembly surface at least in correspondence with part of the first element.

Abstract: A bearing assembly includes at least one rolling bearing unit having an outer race and an inner race rotatable relative to the outer race, and two annular bodies of plastic material overmoulded on the outer race and the inner race, respectively, of the bearing unit. At least one of the two annular bodies has a free cylindrical surface. One of the two bearing races forms a radially extending flange having a cylindrical end surface, circumferentially continuous or discrete, which ends flush with the free cylindrical surface of plastic material.

Abstract: A cartridge bottom bracket is for a bicycle having a tubular shell with a bore. The bottom bracket includes a spindle having opposing ends and a sealed cartridge disposed within the shell bore and about a central portion of the spindle so as to define opposing free end portions of the spindle. The cartridge includes a pipe having opposing ends, two rolling contact bearings disposed within the pipe adjacent to a separate one of the pipe ends and rotatably coupling the spindle with the pipe, and a tubular spacer disposed about the spindle and extending between the two bearings so as to establish a spacing distance between the bearings. Further, two shaped caps are each mounted on a separate one of the free end portions of the spindle and are disposed axially against a separate one of the bearings to enclose the free end portion of the spindle.

Abstract: The assembly (10) includes at least one rolling bearing unit (20) having an outer race (21) and an inner race (22) rotatable relative to the outer race, and to annular bodies of plastic material (30, 40) overmoulded on the outer race (21) and the inner race (22), respectively, of the bearing unit. At least one of the two annular bodies (30, 40) has a free cylindrical surface (41). One of the two bearing races (21 or 22) forms a radially extending flange (25) having a cylindrical end surface (26), circumferentially continuous or discrete, which ends flush with the free cylindrical surface (41) of plastic material.

Abstract: The device includes an annular body (10) of rubber or elastomeric material associated with an annular reinforcing insert (20). The body (10) forms an oil-guard lip (15), a dust-cover lip (12) and a peripheral static sealing lip (13). The insert (20) is produced from plastics material and forms a discoidal annular portion (21) for supporting and connecting the lips (12, 13, 15). The insert (20) also forms a reinforcing structure (22) which projects axially from a radially internal region of the discoidal portion (21) and which is attached to the oil-guard lip (15) in order to ensure that that lip exerts controlled radial contact pressure against the stem (S) of a shock-absorber.
