Added value for your investment
Our Performance Line dampers offer excellent value for your money and are among the latest damper innovations for the following bogie applications:
- Primary vertical
- Secondary vertical
- Secondary horizontal
These high quality products provide a maintenance free superb operation until the next planned major overhaul of the bogies. After this time, and depending on the configuration, the product can be replaced by a new damper, or be overhauled in a specialized workshop.
The production line for these dampers makes use of the latest production technologies, which results in a high level of automation and the elimination of unnecessary handling.
Due to the smart damper design and the efficient manu- facturing process, we are able to offer these dampers at very attractive price levels. These dampers are optimized to achieve the lowest possible initial purchase price without compromising the quality of the product.
Unique features
- Robust construction resulting in a long service life
- Symmetrical force in extension and compression
- Linear force rate up to a freely defined blow-off point
- Maintainable or sealed construction at customer’s request
- The special synthetic rings around the piston and the guide result in the absence of any metal to metal contact
- High quality silent blocks
- Noise-free valve systems

Operating principle
Our Performance Line dampers operate according a two- directional oil flow through the piston. The construction of the damper is such that the damping forces during the extension and compression stroke are symmetrical.
During the extension stroke the damping is performed by a valve stack below
the piston, while during the compres- sion stroke the valve stack on top of the piston creates the desired damping forces.
Characteristics
The characteristic of a Performance Line damper can be customized to suit the customer requirements in the linear (normal) operation area, as well as in the blow-off area at high damper speeds. The following maximum damping rates and damping forces apply for the various damper types within the Performance Line:
