In the field of rail vehicle technology, availability, durability, and safety are among the top priorities. Whether high-speed trains, freight cars, or light rail vehicles — the components used must be able to withstand extreme loads and changing environmental conditions over the long term. Seals and plain bearings from ttv make a decisive contribution to the reliability and cost-effectiveness of rail systems — for years to come.
Rail vehicles are used daily over long distances – often under extreme conditions. This results in clear requirements:
• Extreme temperature fluctuations
• High levels of dirt and moisture (e.g., brake dust, slush, oil)
• Constant vibrations and shock loads
• Long maintenance cycles and high service life requirements
• Compliance with railway-specific standards (e.g., EN 45545, DIN 27201, etc.)
ttv meets these challenges with heavy-duty, customer-specific sealing and plain bearing solutions that are both technically and economically impressive – and have proven themselves in daily railway use.
With in-depth development expertise, a broad portfolio of materials, and decades of experience, ttv supplies reliable system components for manufacturers and maintenance providers of rail vehicles. The combination of robust technology, intelligent design, and tested quality made in Germany ensures maximum operational reliability while reducing downtime and maintenance costs.

REQUIREMENT:
High mechanical load capacity, precise fit for backlash-free guidance, low friction, corrosion resistance, and low-maintenance operation over long periods of use.
SOLUTION APPROACH:
ttv supplied specially designed plain bearing bushings that were tailored to the respective load profiles of the coupling systems. The materials and surface treatments used were specifically selected to ensure that they remain functional even under changing climatic and mechanical conditions.
RESULT:
The ttv plain bearing bushings enable precise, durable, and maintenance-friendly bearing within the train coupling. The solution has already proven itself in years of real-world use with significantly reduced maintenance intervals, higher functional reliability, and stable performance over the entire life cycle of the coupling.
From bogies to roofs, ttv supplies sealing technology and plain bearing solutions that stand for safety, cost-effectiveness, and reliability in the railway industry. Our engineering expertise, coupled with application-specific know-how, makes us the ideal partner for manufacturers, operators, and maintenance providers in the railway sector.
