What lubricant should be used for train bearing lubrication?

Lubricant for Train Bearing Lubrication

Client Question: Could you please tell me what lubricant I can use for train bearing lubrication? We need a lubricant that retains its properties for as long as possible because our trains cover millions of kilometers.

Our Response: The correct consistent lubricant is Molyduval Pegasus LKA 2.

Lubricants must be certified according to DIN EN 12081 and DIN EN 12082 standards.

Train wheel lubrication needs to function across a very wide temperature range, at varying speeds, and with vibrations. Lubricants intended for train wheel bearings must be certified according to DIN EN 12081 and DIN EN 12082 standards to be used in Europe. The strict certification approval process involves several separate tests to verify the chemical and mechanical properties of the lubricant under the most challenging conditions.

The key factor affecting the lubrication of train mechanisms is the ongoing cost of labor and product.

The total cost of ownership (TCO) for trains primarily depends on the longevity of their mechanisms and future maintenance intervals. Trains and carriages require maintenance multiple times throughout their operational life. Wheelset maintenance and repair can be particularly expensive. Currently, the most popular lubricants on the market are lithium-based mineral oil greases, which provide lubrication for up to approximately 600,000 kilometers or eight years of use. However, with increasing load capacity and rising cost pressures, it is already clear that such lubricant mileage will not suffice in the future. Therefore, attention is turning toward heavier-duty lubricants that can provide lubrication for up to 1.3 million kilometers and more. This can be achieved with the modern lubricant, Molyduval Pegasus LKA 2.

This synthetic grease is designed for high temperatures, heavy loads, and long service intervals. Thanks to its advanced formulation, Molyduval Pegasus LKA 2 forms a durable lubricating film, resulting in significantly reduced wear and lower temperatures in roller bearings.

Molyduval Pegasus LKA 2 also provides excellent protection against wear and has strong resistance to oxidation and corrosion. Its potential usage lifespan is over 1.3 million kilometers. Furthermore, Molyduval Pegasus LKA is an environmentally friendly lubricant, as it reduces both lubricant and CO2 consumption due to increased operating time and extended lubrication intervals.

Technical Benefits Summary

By instantly forming a load-resistant lubricating film, this special lubricant can quickly separate friction components, functional surfaces, and anti-friction bearing rollers. This significantly reduces wear and increases the lifespan of the bearings. Special additives also provide effective protection against corrosion, as well as increase pressure and oxidation resistance, thus extending the working life and quality of the lubricant. Molyduval Pegasus LKA 2 also allows for significantly extended maintenance intervals.

Thanks to the unique composition of various synthetic base oils, Molyduval Pegasus LKA 2 guarantees high performance across a wide temperature range.
