Abstract: A seal arrangement for rollers which permits axial displacement of a roller and its shaft with respect to their supporting bearing. A sealing ring which is generally L-shaped in cross-section has one radial arm of the L mounted on the shaft and against the roller, to provide a seal with respect to the roller. The other arm of the L extends axially away from the roller and has an outer circumferential surface which lies closely adjacent an inner surface of the bearing housing to provide a seal with respect to the housing. Lamellar rings may be provided between the bearing housing and the sealing ring.

Abstract: A rapidly rotating shaft for a wire-rope-stranding machine or the like, comprising a plurality of tubular sections interconnected by flanged coupling sleeves, has a journal bearing for each coupling sleeve whose inner race is unitary with that sleeve while its outer race is a ring closely surrounded by a cylindrical housing. The ring and the housing are provided with aligned bores for the introduction of lubricant; an annular cage between the two races, having a multiplicity of peripherally spaced pockets engaged by respective bearing rollers, is provided with apertures between these pockets facilitating the passage of the lubricant to the inner race.
