          Cartridge roller

          Cartridge roller

          Provides the reduction of unsprung bogie weight and improvement of ride performances;

          The adapter design enables to improve the testability and safety during repair because of the availability of wear indicators and safety lug-bosses;

          The adapter is characterized by a high wear resistance due to reinforced high-duty cast iron used and the service life when the run of the bogie is reached 1 500 000 km;

          The bearing provides the warranty lifetime 800 000 km;

          Use of a case bearing and an adapter enables to provide significant reduction of service costs for a wheel set.

              Friction shock absorber

              Friction shock absorber

              Friction wedges are made of high duty cast iron, that provides stable friction characteristics, as well as increases its service life;

              A fundamentally new 3-D geometry raises the bogie stiffness;

              Provides the testability of the bogie when operated due to use of visual wedge wear indicators;

              Has a wear life time when a bogie run reaches 1 500 000 km.

                    Fixed contact side bearings

                    Fixed contact side bearings

                    Improve the dynamic quality of freight cars;

                    Have high wear resistance of the friction couple when a bogie run reaches 1 000 000 km;

                    Provides the testability of the bogie when operated due to use of visual wear indicators;

                    Use of springs as spring units enables to keep consistent power characteristics of bearings at a low temperature.

                            Bolster

                            Bolster

                            The bolster's geometry provides availability of a stress-ration condition when loaded;

                            Enables to install different types of removable bearings on the mounting surface;

                            Center plate's sizes enable to roll a bogie to all existing types of freight cars;

                            Removable wear-resistant parts of the central plate enable to protect the central plate against deterioration and their service life is 500 000 km of the bogie run;
                             
                            Removable wear-resistant parts of bolster pockets enable to protect the bolster against deterioration and their service life is 1 000 000 km of the bogie run .
