The lubrication of switch gears in a Nordic country with a wide ambient temperature range was a challenge for COGELSA. Improving the working performance of the switch sliding plates was a success.

The key, COGELSA Calcograf Bio Fluid: a biodegradable grease with graphite, specially designed for flange spray lubrication on railways with working temperatures from -20°C to +120°C.

After two years of manual lubrication with COGELSA Calcograf Bio Fluid:

➡️ The grease remains on the sliding surfaces for a long time, both in the middle of winter and summer, in dry and rainy weather.
➡️ The lubrication interval has been increased.
