Cylindrical roller bearing i.e. multi ring-eccentric roller bearing for e.g. sheet printing machine, has indentations and recesses feeding lubricating grease in bearing to contact of rollers and discharging excess grease into storage
Cylindrical roller bearing i.e. multi ring-eccentric roller bearing for e.g. sheet printing machine, has indentations and recesses feeding lubricating grease in bearing to contact of rollers and discharging excess grease into storage
The bearing (1) has cylindrical rollers (12, 13) held relative with each other in regular distance by plastic-window cages (23, 24). The cages include cage bars uniformly distributed across the circumference between cage rings of same diameter. Multiple additional indentations and molded recesses are arranged in the cage rings and at cage bars of the window cages. The indentations and the recesses feed lubricating grease in the bearing to a rolling contact of the rollers in required minimal quantity and discharge the excess grease into surrounding grease storage (6).
