DIN 51825 classification of plastic greases
The most common are as follows:
- DIN 51825 K – grease made from high viscosity mineral and/or synthetic oil with a thickener.
- DIN 51825 KP-K – grease made from additional additives that reduce friction and protect against wear in mixed friction locations.
- DIN 51825 KF – K grease with additional hard additives (graphite, molybdenum disulfide).
- DIN 51825 KPF – K grease with additional additives that reduce friction and protect against wear in mixed friction locations, plus additional hard additives (graphite, molybdenum disulfide).
