SKF railway bearings enable continuous and efficient operation with minimal maintenance in wet and contaminated environments. Reliable railways are essential to global travel and logistics, and keeping trains running smoothly is key. SKF provides products and solutions as well as the right services for every step.

The train’s drivetrain gearbox and traction motors must be powerful, sustainable, cost-effective and low-maintenance. These requirements are becoming increasingly important due to longer maintenance intervals and the increasing weight of railway vehicles.

Traction motors must be able to provide high speeds and handle shock loads, but also withstand low-load conditions, such as in coasting or cruise control mode. In addition, sensitivity to discharge also poses unique design challenges to traction motor bearings.

Gearbox design requirements also place high demands on gearbox bearings and bearing arrangements. Specific challenges include operating temperature ranges, high shock loads, and increased overall loads combined with drive units to reduce friction within the gearbox and reduce energy consumption.

SKF implements the latest requirements, innovates and provides high-quality railway bearing products. Keller has extensive experience in railway bearings and has SKF railway bearings in stock. SKF transmission system bearings are designed to handle high levels of contamination and operate in humid environments and under conditions of speed, temperature, load, vibration and shock changes. In addition to developing new innovative solutions, Keller bearings also provide a range of commonly used bearings and bearing units with good field experience, as well as reference materials for transmission systems, so that you can choose the right corresponding products.
