A deep groove ball bearing providing an inner ring, an outer ring and a plurality of balls being arranged between the inner ring and the outer ring. The inner ring and the outer ring each include a raceway for the plurality of balls. Each raceway encompasses the plurality of balls symmetrically. The deep groove ball bearing is lubricated by a lubricant being arranged on each axial side of the plurality of balls. The raceways are offset in the same axial direction from the axial center of the inner ring and the outer ring such that the raceways are offset to the axial side of the deep groove ball bearing where the shear rate acting on the lubricant is higher than on the other axial side of the deep groove ball bearing.

Deep groove ball bearing

A bearing assembly including a bearing having a first ring with a hole, two front edges and an outer cylindrical surface, and a second ring with a hole, two radial edges and an outer cylindrical surface is provided. The first and second rings rotate relatively about a central axis. The bearing includes at least one row of rolling elements housed in a chamber formed between an outer cylindrical surface and a hole of the rings, the first and second rings and the rolling elements determining a pitch diameter of the bearing. A sealing means is provided having an engagement portion rigidly connected to one of the rings and a tapered annular body extending from the engagement portion towards the other ring. When idle, the body forms a non-zero angle with a plane perpendicular to the pitch diameter and is in direct or indirect contact with the other bearing ring.

Bearing assembly

A rolling bearing assembly including a rolling bearing provided with a first race having a bore, two front edges and an outer cylindrical surface, and with a second race provided with a bore, two front edges and an outer cylindrical surface. The first and second races rotate relatively about a central axis. The assembly is intended to be mounted in a housing. The assembly provides at least one first annular flange that is secured to the first race and at least partially covers a front edge of the first race, and at least one second annular flange that is secured to the second race and at least partially covers a front edge of the second race. Free ends of the first and second annular flanges are in sliding contact. The difference in dimensions between the housing and the rolling bearing is compensated by the flanges.

Rolling bearing assembly

The bearing provides an inner race, an outer race, at least one row of rolling elements, and at least one cage for spacing apart the row of rolling elements. The bearing further provides at least one seal that includes means for hooking which are configured to permit the retention of the seal on the cage in at least two predetermined axial hooking positions relative to the outer and inner races.

The invention relates to a bearing assembly providing a bearing having a first ring with a hole, two front edges and an outer cylindrical surface, and a second ring having a hole, two front edges and an outer cylindrical surface, the first and second rings being relatively in relative rotation about a central axis. At least one row of rolling elements is housed in a bearing chamber formed between an outer cylindrical surface and a hole of the rings. The assembly is configured to be mounted in a housing. The assembly also includes at least one envelope mounted on one of the rings of the bearing, such that a dimensional difference between the housing and the bearing is compensated by the envelope.

An instrumented bearing, which includes an outer race and an inner race between which a rolling chamber is delimited. Rolling bodies are disposed in the rolling chamber. The bearing additionally includes a member isolating the rolling chamber from the outside; and a measuring device including at least one sensor adapted to measure at least one operating parameter of the instrumented bearing. At least one measuring device can be mounted to the member isolating the rolling chamber from the outside.

Instrumented bearing and method of manufacturing such an instrumented bearing

A rolling element bearing comprising inner and outer rings; a plurality of rolling elements disposed between opposing surfaces of the inner and outer rings; and a bearing shield comprising a first member having an annular surface facing the plurality of rolling elements, the first member either (1) extending from the inner ring towards the outer ring (defining a gap between the first member and the outer ring) and the inner ring having a low surface energy surface adjacent the gap, or (2) extending from the outer ring towards the inner ring (defining a gap between the first member and the inner ring) and the inner ring comprises a low energy surface adjacent the gap. The low energy surfaces each have a surface energy of &#x2266;0.028 N/m.

Bearing

A mechanical system comprising at least one moving component and a lubricant. The mechanical system also comprises a plurality of at least one type of microcapsule consisting of a shell, which, under the effect of a variation of a given characteristic physical parameter of the mechanical system, is capable of releasing particles. The dispersion of the particles is identifiable by a system located external to the mechanical system.
