Bellow
Rubber bellows reliably protect the moving components of railway vehicles from dirt, moisture and mechanical stress, thereby ensuring long-lasting and trouble-free vehicle operation.
Area of application
Rubber bellows are essential protective components in railway vehicle construction and are used wherever moving parts need to be reliably protected from dirt, moisture, and mechanical stress. Among the most important areas of application are wheel set guide elements, joints, coupling systems, brake components and moving parts in the underfloor area. Especially in areas with high levels of dirt and moisture, bellows ensure that safety-critical components remain fully functional over the long term and are protected from premature wear.
Technical details
The technical specifications of rubber bellows are based on a combination of elastic, highly durable rubber materials and sturdy metal fittings or flanges. Depending on the application, the bellows can be manufactured with different geometries, wall thicknesses, Shore hardness ratings and temperature resistance. Many systems feature a modular design, are easy to install, and are engineered to withstand high dynamic movements and extreme environmental conditions.
Characteristics
The key properties of rubber bellows include their high flexibility, excellent sealing performance and resistance to temperature fluctuations, moisture, oils, dirt and chemical exposure. They protect moving components from abrasion, corrosion and dirt particles, thereby playing a crucial role in extending the service life of wheel-set-guiding elements, joints, and coupling systems. At the same time, they reduce maintenance requirements, increase operational safety and support reliable, long-lasting vehicle operation in daily rail traffic.
