Abstract: A trolley assembly for a conveyor includes a wheel assembly and a trolley arm. The wheel assembly includes a wheel that is rotatably mounted to an axle, with the axle extending along an axis of rotation of the wheel and comprising a mounting portion that is non-rotatably mounted to or at least partially received in the trolley arm. The mounting portion of the axle may be inserted into a passageway and at least partially expanded to limit retraction of the axle from the passageway, or a fastener or other retaining means may secure the axle at least partially within a passageway of the trolley arm. The mounting portion of the axle may comprise a non-cylindrical mounting portion that is received in a non-cylindrical-shaped passageway of the trolley arm.

Abstract: A trolley for a conveying system includes a first trolley arm with a trolley wheel rotatably mounted thereon, a second trolley arm with a trolley wheel rotatably mounted thereon, and a load bar. The trolley wheels roll along a track of the conveying system to move the trolleys along the conveyor track. The first trolley arm connects to a first attachment element, which includes a base portion and an attaching member that are integrally formed together. The load bar connects to the second trolley arm and to the attaching member of the first attachment element. The load bar has a slot proximate to one or both ends for receiving the attaching member. The attaching member is retainable in the slot, such as via a retaining pin. The first and second trolley arms are connected together via the load bar.

Abstract: A trolley wheel assembly includes a wheel portion rotatably positioned around a hub portion and at least one sliding member positioned between the wheel portion and the hub portion. The sliding member defines a mating surface for mating with a generally correspondingly formed mating surface of the wheel portion and/or the hub portion. The mating surface of the sliding member defines a radial projection at least substantially circumferentially around the sliding member. The radial projection may slidably mate with the generally correspondingly formed mating surface of the wheel portion and/or the hub portion to facilitate rotation of the wheel portion about the hub portion. The wheel assembly may include one or more inserts that define the correspondingly formed mating surface and that are positioned between the sliding member and the wheel or hub portion to facilitate manufacturing and assembly of the wheel assembly.

Abstract: A sealed bearing assembly including an inner race, an outer race, and a plurality of balls forming therewith a bearing, a pair of closure members along the sides thereof, and a pair of identical annular seals positioned between the bearing and the closure members, is constructed such that an annular pocket is formed by the seals about the rolling elements. The seals act to confine lubricating material within the pocket to only the specific volume where it is needed. The seals not only preclude seepage of the lubricating material, but also facilitate the economical use of modern greases.
