The SV RailLine 60-serie dampers are unique damper innovations introduced by SV for almost every application: Primary vertical, Secondary vertical, Secondary horizontal, intercar damper and YAW dampers. The operating principle of 60-series dampers is based on a two-directional oil flow through the piston. This smart design offers unbeaten combination of enhanced stiffness and low weight.
Yaw, vertical, and horizontal dampers are essential components in enhancing the performance and ride comfort of rail vehicles. SV’s dampers stand out not only for their durability but also for their precise engineering in each of these applications.
A yaw damper is a key component in modern rail systems, used to control side-to-side rotational movement of the vehicle around its vertical axis, improving stability, comfort, and safety, especially at high speeds or in curves. Vertical dampers absorb vertical motions caused by irregularities in the track, helping to improve ride comfort and ensure consistent wheel-to-rail contact. Horizontal dampers, meanwhile, manage lateral movement, especially in curves or at high speeds, contributing to greater vehicle stability and reducing the risk of derailment.
We are excellent at manufacturing dampers of any kind.
Unique features of SV RailLine
- Robust construction resulting in a long service life
- Unique non-wearable seals, guarantees non leaking
operation for extreme operation life - Symmetrical or asymmetrical force in extension
and compression - Maintainable construction (with welded or threaded
dust cover tube) - Damping force adjustment by adding or removing
valve spring plates - Non metallic guide surfaces in piston and piston rod
- High quality silent blocks
- Noise-free valve systems
- Low weight as a YAW-damper

Specially developed for an extremely long operational life
These high quality products are designed to provide a fully maintenance free operation until the next planned major overhaul of the bogies. In many cases our RailLine products are in use even after 15-25 years. This important fact demonstrates the minimal maintenance required.
Even after a very long operational life time, depending on the configuration, the product may be overhauled in a specialized workshop.
