A roller of a support arrangement for a rotary milking platform, where the support arrangement includes a first rail member fixedly connected to the rotary platform, a second rail member stationarily arranged in a position below the platform, and a plurality of rollers arranged in a vertical space between the first rail member and the second rail member. Each roller includes a peripheral surface comprising a contact surface to be in contact with a contact portion of the first rail member and a contact portion of the second rail member. The peripheral surface of the roller includes two beveled surfaces arranged at opposite sides of the contact surface which are located at a smaller distance from a rotary axis of the roller than the contact surface.

A roller bearing comprising an inner ring, an outer ring, and a bearing cage positioned between the inner ring and the outer ring. The bearing cage includes a spine and a plurality of pins disposed one side of the spine that are coplanar or offset with a plurality of pins disposed on an opposite side of the spine. A roller is rotationally coupled to each pin such that each roller is coplanar or offset with another roller on the opposite side of the spine.

A roller bearing assembly (100) including an outer cup (110) having a first end, a second end, a body (116) extending therebetween defining an outer raceway (118), a first flange (112) disposed on the first end of the body and a second flange (114) disposed on the second end of the body, a plurality of rollers (130), each roller including a first projection (134) extending along its longitudinal center axis, and a first retainer ring (140a) having a base side wall, an inner side wall and an outer side wall, the inner side wall and the outer side wall extending outwardly from the base wall, wherein the base wall of the first retainer ring is disposed adjacent an inner surface of the first flange and the first projection of each roller is rotatably disposed between the inner side wall and the outer side wall of the first retainer ring.

A high load capacity bearing that includes a cylindrical outer sleeve that fits around a separable cylindrical outer race assembly. The outer race assembly includes a set of non-helical grooves formed on its inside surface that mesh and engage teeth formed on the outside surface of a plurality of rotating rollers that are longitudinally and axially aligned inside the outer race assembly. The rollers are longitudinally aligned and evenly space apart and rotated as a unit inside the outer race assembly. Located inside the rollers is an inner race with non-helical grooves formed on its outside surface that mesh and engage the teeth on the rollers. The inner race includes a smooth inside bore that fits around the support surface on a shaft. During use, the inner race is becomes fixed on a support surface on a shaft and the outer sleeve and outer race assembly are mounted on a part.

A bearing arrangement having an inner race and an outer race, between which rolling elements are disposed, the rolling elements being accommodated in a bearing cage. At least one rolling element is designed as a sensor rolling element, and the bearing cage is designed as a pin cage having multiple pin elements that at least partially accommodate the rolling elements and the at least one sensor rolling element, and a sensor rolling element for a bearing arrangement of this kind are disclosed.

A roller circle assembly for heavy machinery includes an upper circular rail and a lower circular rail concentrically arranged about a central axis, and tapered rollers between the upper and lower rail. Each tapered roller includes a flange having an angled and convex flange contact surface that contacts the lower rail. The lower rail and/or the upper rail can include an angled surface configured for contact with the flange contact surface. The geometry of the rollers and the lower rail are configured to reduce the stresses applied to the rollers and lower rail due to contact between the flange contact surface and the angled surface.
