DIN 51517 classification of gear lubricants
The most common are as follows:
- DIN 51517 CGLP – lubricants have additives that protect from corrosion, oxidation and wear in mixed friction locations and additives improving the surface friction characteristics.
- DIN 51517-3 CLP – lubricants have additives that protect from corrosion, oxidation and wear in mixed friction locations.
- DIN 51517-2 CL – lubricants have additives that protect from corrosion and oxidation, and are suitable for medium load conditions.
