Side bearers are fitted on the sides of bogies for freight wagons and support the vehicle body. When the bogie rotates, the centre pivot liner and the two side bearers work together, ensuring reliable operation thanks to a defined coefficient of friction and turning torque.
Because the bearers are used outdoors, they are exposed to fluctuating temperatures and different kinds of precipitation throughout the year.
Side bearers are rectangular plates that are available in a range of thicknesses and with fastening bores in various positions. It is vital that the bearers require no lubrication and are maintenance-free, and both PAS-80X and PAS-80X GK5 are ideal materials for the job. This is reflected in their decades-long application and their approval by DB AG as a side bearer in spring-loaded contact.
faigle side bearers are prefabricated using extrusion or injection moulding and then mechanically finished. After that, heat treatment lasting several days is necessary to ensure that the material has the required properties.
- Lubricant-free, maintenance-free
- Durability for an entire service interval
- Physiologically safe
