341.00.000 and 342.00.000 hydraulic dampers are designed for use in central and axle-box spring suspensions of 81-740/ 741 series subway cars and their versions. Damper design embodies solutions that has well demonstrated their reliability over long runs on domestic long-haul locos and electric trains.
All dampers have been manufactured with a 70mm dia cylinder, import seals and advanced valve system since 2010. Such upgrades enhanced dampers' reliability and mileage between repairs.
