KRAFTLER DAMPING SYSTEMS CONSTANT CONTACT SIDE BEARINGS type a typf r Free height, mm 144-2 Travel, mm 19.5±1 End force (at the end of travel), kN 27 Additional travel, mm +10 minimum End force (at the end of additional travel), kN 300 Max. Force, kN 460 Free height, mm 134-2 Travel, mm ll.lil End force (at the end of travel), kN 23 Additional travel, mm +10 minimum End force (at the end of additional travel), kN 300 Max. Force, kN 460 In comparison with the existing Constant contact side bearings, all excessive impact loads on the bogie bolster and the car body are smoothed. At the same time, the closure of the cap with the housing does not occurs, so the elastomeric pad is protected from large loads and is capable to smooth over loads up to 460kN without any damages (patent). Protected from temperature fluctuations, associated with climatic conditions or with heating during the working process. Pleating or cooling of Constant contact side bearings doesn't lead to changes in its overall height, which is important for ensuring high stability of its operation under alternating cyclic loads CONSTANT CONTACT SIDE BEARINGS Are made of two types - long-stroke type A, for installation on high-speed wagons, and short-stroke type B, for installation on wagons operating at low speeds.
