Cylindrical roller bearings for integrated planetary gear bearing arrangements
Industrial gearboxes are being designed as increasingly compact with smaller design envelope while their power levels are continually increasing. This increase in power density within a very small space places increasingly high demands on the rolling bearings used. This is particularly true for planetary gearboxes in industrial gearboxes, since such gearboxes must transmit very high power levels with high operational security within a very small design envelope. In more than a few cases, the planetary gears in particular are subjected to loads up to their physical limits. At the same time, the planetary carriers and planetary pins are subjected to heavy reversed bending loads. For this demanding area of application, bearing solutions are only accepted if the bearing arrangements not only have a reduced design envelope and give quiet running but also have low friction, extremely high reliability levels, a very long life and are very easy to fit. With the right cylindrical roller bearings for the requirements in planetary gearboxes, Schaeffler can offer solutions that deliver major customer benefits.
