Bogie Components:
Safety Starts with the Bogie
Precision engineering for safety and smooth operation.
Product Groups
Vibration isolation, springs, metal-rubber elements, shock absorbers, and bearing components—all product groups from a single, technically skilled source.
Vibration Isolation
Protection of Vehicles and Infrastructure
Vibration-isolating elements protect both the vehicle and the track infrastructure from harmful dynamic loads. They reduce structure-borne noise and wear and tear, and provide a lasting improvement in ride comfort.
Typical Products & Components:
- Elastomeric Bearings for Bogie Frames
- Vibration Dampers & Anti-Resonance Mounts
- Structure-Borne Sound Isolator
- Rubber-Metal Composite Elements for Structural Damping
- Acoustic Decoupling Solutions
Primary and Secondary Springs
Core component of the suspension system
The primary suspension connects the wheel set to the bogie frame, while the secondary suspension supports the car body. Both systems are critical to safety and require certified products with precise spring characteristics.
Typical Products & Components:
- Elastomer primary springs (conical, cylindrical)
- Secondary air springs, including bellows and height adjustment
- Coil Springs (Primary & Secondary)
- Progressive springs for heavy-duty vehicles
- Spring Mounts and Spring Plates
Metal-Rubber Components
A Combination of Strength and Flexibility
Metal-rubber components combine mechanical strength with elastic flexibility. They are used in applications where specific spring rates and high strength are required.
Typical Products & Components:
- Bushings (radial, axial)
- Silent blocks for handlebars and cross members
- Articulated components for bogie articulation
- Metal-rubber composite bumpers
- Centering Discs and Stop Elements
Shock Absorber
Mastering Dynamic Forces
Hydraulic and gas-hydraulic shock absorbers in the bogie are responsible for vertical and horizontal ride dynamics. Their function is critical to safety and must be verified at defined test intervals.
Typical Products & Components:
- Vertical dampers (primary and secondary levels)
- Transverse Damper for Drive Guide
- Yaw Damper for High-Speed Vehicles
- Hydraulic damper with adjustable characteristics
- Rubber Buffers and End Stops
Bearing Components
Reliable under extreme loads
Roller bearings, axle bearings, and bearing housings form the foundation of the entire chassis. Failures in this area can have catastrophic consequences—the quality and traceability of every component are therefore non-negotiable.
Typical Products & Components:
- Axle bearing assemblies (integrated assemblies or individual parts)
- Cylindrical roller bearings for wheel set bearings
- Tapered roller bearings for combined loads
- Bearing housings and adapter rings
- Gaskets and Spacer Rings
Challenges in Bogie Spare Part Procurement
Procuring safety-critical bogie components is a complex process. Product obsolescence, global supply chains, and strict certification requirements present challenges for operators and maintenance providers that call for technical expertise and reliable supply networks.
ASTRA specializes in exactly these situations — as a partner that not only delivers but also thinks proactively.
Obsolescence
Rail vehicles remain in service for decades. ASTRA ensures the long-term availability of components through alternatives, final purchases, and suitable replacement solutions.
Long delivery times
Long lead times? ASTRA minimizes risks through strategic inventory management, framework agreements, and an international supplier network.
International Procurement
ASTRA handles international procurement—from supplier selection and quality assurance to seamless customs and logistics processing.
Sustainable Supply Solutions for Safety-Critical Components
ASTRA is taking a broader view of procurement—from technical evaluation to long-term supply security.
Technical Evaluation Instead of Blind Delivery
Our experts conduct a technical analysis of every inquiry. Drawings, standards, installation orientation, and load profiles are reviewed before a supplier is selected.
Compliance as the Standard, Not an Option
Safety-critical components leave ASTRA only with complete documentation: factory certificate, declaration of conformity, and traceability back to the raw material.
Sustainable Supply Strategies
We don't think in terms of individual deliveries, but rather in terms of supply strategies. Framework agreements, inventory options, and obsolescence planning ensure availability throughout the entire vehicle life cycle.
Global Network, Local Responsibility
Through our international partner network—which includes Trelleborg and ContiTech, among others—we are able to source products even in situations where direct negotiations would be virtually impossible for individual customers.
