Abstract: The suspension bump stop device comprises a rolling bearing (44) that forms an axial bump stop, equipped with an upper ring (46), with a lower ring (48) and with a plurality of rolling elements positioned between the rings, the upper and lower rings being supported respectively by an upper cup (40) and a lower cup (42), the lower cup forming a bearing means for a suspension spring (18), at least one sealing lip being provided on one of the cups so that it bears against a bearing surface portion of the other cup. The bearing surface portion is substantially cylindrical, the sealing lip being directed downwards away from the rolling bearing and bearing with radial interference against the said surface portion, the said substantially cylindrical surface portion being connected towards the top to a shoulder against which the lip can bear if the two cups become radially eccentric relative to one another.

Abstract: Rolling bearing having an inner ring (1) and an outer ring (2) with a row of rolling elements (3) held by a cage (4) between bearing races provided on the two rings, and an annular housing (5) surrounding one of said rings. Said ring forms with the housing at least one closed space (21a), (21b), inside which a lubricant is located.

Abstract: Freewheel device 1, of the type comprising an outer race 2 which has an inner track 3, an inner race 4 which has an outer track 4, a freewheel 6 situated between the tracks of the said races, at least one member 7 forming a bearing intended to keep the said races 2, 4 concentric, and at least one lateral retaining endplate 12, secured to one of the races in order axially to hold the freewheel 6 and the member forming the bearing with respect to the said race. The endplate 12 comprises a first radial portion 12a adjacent to the corresponding holding member 7 for retaining it axially, and a second more or less radial portion 12b cut into tabs projecting into an annular groove 21 formed in one of the races, the said endplate coming into contact with a side wall 21a of the said groove.
