Urban rail shock absorber solutions
Developed for tram, metro and light rail applications, the K148 series combines precisely adjustable damping characteristics with compact, lightweight construction. Its space-efficient architecture makes it particularly well suited to modern urban vehicles and low-floor bogie designs.
Urban rail vehicles place exacting demands on suspension components. Frequent acceleration and braking, varying passenger loads and limited installation space call for damping solutions that maintain consistent performance throughout intensive daily operation.
The K148 applies the proven damping principles of the K147 platform within a lighter and more compact architecture. Independent adjustment in both damping directions enables each configuration to be precisely matched to the vehicle layout, operating conditions and technical requirements.
Key features
- Broad damping-force adjustment range
- Independent adjustment in both damping directions
- Configurable for different vehicle layouts and operating requirements
- Developed for tram, metro and light rail applications
- Compact and lightweight construction
- Designed for refurbishment and reuse
- No metallic contact between friction elements
- KARSUS valve technology for consistent damping performance
The compact architecture of the K148 series enables integration into low-floor bogies and other space-constrained installations. Derived from the K147 platform, it retains precise, application-specific damping control while reducing installation space and overall weight.
