Hub 50-19-145SP (bolotnaya) as a multi-stage hollow body of rotation weighing 11.4 kg with mounting holes for a gear ring, a very important part of the on-board gearbox of the T10M tractor (B10M bulldozer), related to the casing assembly of the drive wheel with its hub, half-axle, bearings and gears. The hub of the drive wheel has its own design in the crawler design of a number of other special vehicles - tractors and cranes (for example, the RDK-25 crane). However, not every tracked vehicle has such a complex on-board gearbox device as the T10M ChTZ-Uraltrak tractor, with a twin gear and other features. The hub in this on-board gearbox has special "advanced" functions. The design of the above hub is 50-19-145SP; designed for the T10MB swamp tractor.
