Bearings play an important role in both passenger and goods transport. They have to withstand heavy loads: they work at high speeds, under a great weight, are subjected to both static and dynamic loads and play an essential part in the safety of rail vehicles.
Traction motor bearings in rail transport have to be powerful, environmentally friendly and cost-effective. The high weight of rail vehicles and long, maintenance-free operating hours have to be taken into account to guarantee a high degree of reliability and safety. Apart from reducing the weight of the drive train, traction motors in rail transport are subjected to high radial and axial loads as well as the possibility of a strong passage of electrical current and high speeds. Both Cylindrical Roller & Deep Groove Ball Bearings have proven themselves in traction motors for rail vehicles since they are ideal for high speeds and loads and are easy to install and dismantle.
