    Abstract: PROBLEM TO BE SOLVED: To provide a high-strength plastic cage by making simple the assembly thereof. SOLUTION: This cage, which is for guiding a plurality of bearing rollers by separation, comprises a first member 7 and a second member 10 which are made of a plastic material. The first member 7, which projects from one face of a ring part in its axial direction, has a plurality of web parts that comprise a pocket to accommodate the roller, while the second member 10 is a ring member to secure free ends of the web parts. In this case, the first member 7 and the second member 10 have an upright part 15 and a recess part 11, respectively, which are fitted integrably with each other by weld joints being welded that are at different levels apart from each other in the axial direction.

Date May 15, 1997Sealed bearing incorporating an inner race (13) an outer race ring (14) and a row of elongated rollers (15) disposed between, whereby races (11, 12) and rollers (15) have curved longitudinal section profiles and which rollers (15) are axially moveable between the races relative thereto for allowing mutual misalignment of the races, and whereby at least one sealing member (18) is formed separately, positioned axially outside the rollers (15) but adapted to follow the rollers (15) in a free-floating manner and arranged to provide its sealing effect by frictional engagement, wherein at least one of the inner and outer race rings (13, 14) at the axial outer ends of its race (11, 12) is each provided with a radially projecting motion preventing means (20) of short axial width, arranged to prevent the sealing member (18) from being pressed out from the space between the bearing race rings even at misalignments of the race rings (13, 14) relative to each other.

    Abstract: A sealing device for a slot between two elements (1,2), which are rotatable relative to each other, e.g. an outer and an inner race ring in a rolling bearing, incorporates a flexible sealing portion (5) having a lip (4), which contacts a sealing surface (7) surrounding the lip. The sealing portion (5) is rotatable, and the centrifugal force acts upon it thus that it tends to leave the surface (7) at increasing rotational speed. In order positively to avoid that the lip is urged so hard against the surface (7) at high rotational speeds, that an unallowable temperature increase occurs, the sealing portion (5) and the surface (7) have profiles of such shape, that the lip (4) is displaced in a direction which has a component directed radially outwards relative to the rotational axis, when the sealing portion with the lip (4) is bent by the centrifugal force.

    Abstract: A roller bearing with symmetric barrel shaped rollers comprising an inner race (13), an outer race (14) and rollers (11), each of which rollers have at least one rounded end, and being of the bearing type where rollers and race tracks have longitudinal section profiles with substantially the same radius of curvature, whereby the rollers during normal operating conditions are axially moveable between the race tracks without hindrance from axial confinements at the race tracks for allowing relative misalignment and axial displaceability of the race tracks, wherein the end drop zone has a length (d1) which is lower than 5% of the length (1a) of the roller, and which commences where the bend of the curvature of the roller in axial direction exceeds the normal curvature of the roller by 0.1°, and where the end drop of the roller is otherwise determined by the following relations, r/1a>=0.35 for gamma values up to 0.7°, and r/1a is >=0.2 for gamma values between 0.7° and 1.4°.
