Method for manufacturing bearing device for vehicle wheel
A manufacturing method of a bearing device for a vehicle wheel (1) includes: a pressure adjusting step of enclosing, in a work chamber (Rw), the bearing device for a vehicle wheel (1) to which a sealing member (9) on an outer side is fitted in the work chamber (Rw), and adjusting a pressure in the work chamber (Rw) to a predetermined atmospheric pressure (Pt) according to an environment of a use area of the bearing device for a vehicle wheel (1); and a sealing step of fitting a cover (12) that seals an inner side opening (2a) of an outer ring (2) or an inner side sealing member (6) that seals between the outer ring (2) and a hub ring (3) or an inner ring (4) to the inner side opening (2a) in the work chamber (Rw) in which a pressure has been adjusted.
ROLLING BEARING ASSEMBLY INCLUDING A CRIMPED SEALING ASSEMBLY HAVING A GROUNDING ELEMENT
A rolling bearing assembly has a first ring including a first race, a second ring including a second race, and a plurality of rolling elements in rolling contact with the first and second races. The rolling bearing assembly also has a sealing assembly including a first end in contact with the first ring and a second end in contact with the second ring. The sealing assembly has a shield, a sealing element, and a grounding element. The shield has an attachment section in which a free end of the shield is crimped such that it is bent around the sealing element and the grounding element to thereby hold the shield, the sealing element, and the grounding element together with the shield in contact with the first ring and the grounding element in contact with the second ring. The sealing assembly thus creates an electrically conductive path between the first ring and the second ring.
Sealed thrust ball bearing
The inner elastic sealing member 5 includes an inner cylindrical base portion 5A leading to an end portion of an inner cylindrical portion 1B of the inner ring 1, and also includes, at an outer circumferential surface of the inner cylindrical base portion 5A, a projection 7 extending radially outward of an inner periphery of a lower end of an inner cylindrical portion 2B of the outer ring 2. The outer elastic sealing member 6 includes a lip 6B brought into pressure contact with a pressure contact surface B of the outer ring 2. An upper surface 7A of the projection 7 is spaced downward from the lower end of the inner cylindrical portion 2B of the outer ring 2, and an outer circumferential surface 7C of the projection 7 is spaced radially inward from the lower member 8.
CARTRIDGE BEARING WITH BEARING GREASE SETTING MEMBER
A bearing assembly for a vehicle includes an inner race having an interior surface and an exterior surface, an outer race having an interior surface and an exterior surface, a first sealing member disposed between the inner race and the outer race, the first sealing member having a sealing surface adjacent to the interior surface of the outer race, and a second sealing member disposed radially inward of the first sealing member and adjacent to a shoulder surface of the outer race, wherein the first sealing member permits grease bleed-off from the bearing prior to the first sealing member setting against the second sealing member.
BEAD SEALS FOR ROLLING BEARINGS
Bead seals and methods of forming the same are disclosed, for example, for bearing assemblies. A bearing assembly may include an inner ring, an outer ring, and a plurality of rolling elements supported therebetween. An annular seal may be disposed between the inner and outer rings, the seal including a metal portion having a mating surface configured to contact a wall of the inner ring. A bead seal may be secured to the mating surface and may extend around a circumference of the seal, the bead seal contacting and forming a seal between the mating surface and the wall of the inner ring. The bead seal may be secured to/within a groove formed in the mating surface. For example, the bead seal may be over-molded on the groove. The disclosed bead seal(s) may reduce or replace other sealants or sealing members in the assembly.
METHOD OF USING A MOUNTING TOOL TO INSTALL AN H-SEAL IN A BEARING
A method of inserting an H-Seal in a bearing, the H-Seal having two ends, two upper lips, two lower lips and a vertical flange positioned between the bearing that secures the upper and lower lips together, the bearing having seal faces, inner and outer rings and a gap therebetween. The method provides including an insertion tool assembly, priming the H-Seal into the insertion tool, sliding the tool with the H-Seal loaded therein within a slot, placing the lower lips back on their respective face, allowing the lower lips to recover their initial shape. The tool moves the lower lips to a vertical position (T shape), inserts the seal between the rings and the lower lips recover their initial shape and places them naturally back on their respective faces.
H-SEAL MOUNTING TOOL
A tool for inserting an H-Seal in a bearing includes a vertical part assembly having a top portion, a bottom portion, and a freely rolling disc. A first interconnecting portion is configured to engage a second interconnecting portion, the first interconnecting portion configured to receive the vertical part assembly through an opening in the first interconnecting portion. A gripping element connected to the top portion. A rolling disc mounted to the bottom portion of the vertical part assembly. First and second sliding pads having first and second evolutive guides that vary in shape from top to bottom and from back to front. The evolutive guides are configured to pass the H-Seal between the stages of being in a free state with lower lips opened outward, to pre-inserted into the bearing, to inserted into the bearing, to coming down into the bearing, to the lower lips opening outward.
Bearing device for vehicle wheel
A bearing device for a wheel, which has improved axial assembly accuracy of a sealing member by reducing the amount of springback. The bearing device for a wheel comprises an inner sealing member that blocks an inner opening end of an annular space formed by an outer ring and an inner ring. A sealing ring of the inner sealing member has a core metal fitting in the outer ring and an elastic member joined to the core metal. The elastic member has: a pressing part that is pressed inward in the axial direction when the sealing ring is press-fitted into the outer ring; and a non-pressing part that is not pressed inward in the axial direction when the sealing ring is press-fitted into the outer ring, wherein the axial thickness of the pressing part is thinner than the axial thickness of the non-pressing part.
SEALED BEARING ASSEMBLY AND METHOD OF FORMING SAME
A sealed bearing assembly includes an inner race, a bearing element, and an outer race extending radially in axial alignment between a rotatable member having an axis of rotation and a stationary support structure. The sealed bearing assembly also includes a first inlet header coupled to a first axial end of the outer race. The first inlet header includes at least one oil inlet port, at least one oil nozzle, and a first sealing member extending between the first inlet header and a first surface of the inner race.
SEALING GASKET AND VEHICLE COMPRISING SUCH A SEALING GASKET
A sealing gasket includes an outer flange, an inner flange, and a seal. The outer flange comprises a first surface and a second surface, parallel to the first surface and comprises a first opening, centered on a first opening axis, wherein said first opening is ringed by an inside edge of the outer flange, connecting the first surface and the second surface. The inner flange, is arranged inside the first opening and the inner flange is connected to the outer flange through at least one junction tab, the inner flange, the outer flange and each junction tab being made of metal. The seal, is made of elastomer, provided on the inside edge and protrudes from the first surface and the second surface.
