UNITE DE ROULEMENT, EN PARTICULIER POUR LE MONTAGE A REGLAGE DE JEU D'UN AXE DE PALIER DE PEDALIER, COMPRENANT DEUX ROULEMENTS A BILLES A CONTACT OBLIQUE DISPOSES A DISTANCE L'UN DE L'AUTRE.LES BAGUES EXTERIEURES 2, 3 SONT REALISEES EN FORME DE L DONT LES BRANCHES 4, 5 DIRIGEES RADIALEMENT VERS L'INTERIEUR SONT TOURNEES L'UNE VERS L'AUTRE, ET DES ANNEAUX 19, RACCORDES A L'AXE 1 OU ANALOGUE, SONT INSTALLES ENTRE LES BRANCHES 4, 5 DES DEUX ROULEMENTS A FAIBLE DISTANCE DE CEUX-CI. A rolling bearing unit, in particular a play-adjustable bearing arrangement, comprising a bearing shaft, a housing having a bore, and angular contact ball bearings having outer rings arranged in the housing bore and inner rings arranged on the bearing shaft. The shaft is provided with three annular grooves, a threaded portion, and an axial groove along the threaded portion. A locking ring is arranged in the first annular groove, a first cover is arranged on the shaft and abuts the locking ring, and the inner ring of the first bearing abuts the cover. The adjustment of the bearing play is achieved by adjustably arranging a second cover on the threaded portion of the shaft to abut the inner ring of the other ball bearing. The securing of the second cover against rotation relative to the shaft is achieved by deforming or indenting the boss of the cover to engage the axial groove. The outer rings of the bearings are L-shaped and a pair of slotted rings are arranged in the second and third annular grooves of the shaft, between and near the flanges. The slotted rings prevent the balls of the bearings from falling out during shipment and before assembly in a housing.
