Railway Industry

In railway and metro rail operations, lubrication as a maintenance task ensures operational reliability, system safety and passenger comfort. From high-load wheel flange interfaces and axle box bearings to coupler mechanisms, braking systems and door actuators, each component relies on precise and consistent lubrication. Operating under varying speeds and fluctuating temperature conditions these systems demand reliable lubrication solutions that guarantee performance and longevity.

Driving efficiency and safety in Railway & Metro systems through reliable lubrication

Wheel flange: A critical interface for railway performance

Wheel flange is a critical aspect of wheel-rail track interface management in both railways and metro rail operations. The contact between the flange and gauge face, particularly on curves, exposes components to severe pressure, abrasive degradation and fluctuating lateral stresses

Lack of lubrication or insufficient lubrication accelerates wheel and rail wear, increases rolling noise and vibrations, contributing to higher traction energy losses and compromises safety.

Optimally lubricated flanges contribute to equipment longevity, passenger comfort, safety and reliable rail operations. To meet these demands, wheel flange lubricants must deliver exceptional load-carrying capacity to withstand high contact pressures. They should also resist water and contaminants, perform reliably in varied climatic conditions. Additionally, optimized friction control is essential to reduce lateral forces without compromising traction or braking performance.

BECHEM’s Ecorail series represents a new generation of biodegradable, high-performance wheel flange lubricants. Designed for rail-bound systems, these water-resistant, greases provide strong adhesion and excellent wear protection, ensuring consistent performance while remaining environmentally responsible.

Metro Rails: Reliable lubrication for door mechanisms.

In modern metro operations, automatic door closure systems are critical for ensuring passenger safety, punctuality and seamless passenger movement. These mechanisms comprising actuators, guide rails, linkages, rollers and electric motor drives operate under high-frequency cycling, variable loads, and environmental contaminants such as dust, humidity, and temperature fluctuations. The right lubricant ensures smooth, quiet operation of sliding and pivoting parts, reduces friction and wear, prevents dry running, and extends maintenance intervals. For metro doors, lubricants must:

Provide long-term film stability under repetitive motion
Resist oxidation, dust, and moisture
Remain compatible with metals, plastics, elastomers, and electronic components

BECHEM’s high-performance synthetic greases, meet these criteria through its excellent compatibility with metals, plastic and rubber-elastic materials. Its high oxidation and chemical stability extend lubrication life, while its homogeneous structure ensures consistent performance.
