Grease is a consistent lubricant which is made from mineral oil and/or synthetic oil as well as a thickener.
The advantage of grease is its high consistency. Greases enable lubrication to stay where it is needed. It can be used to seal bearings and protect them from intruding dirt and prevent corrosion. Grease consists from mineral or synthetic oil, additives and thickeners like lithium, natrium and calcium soaps. The base oil and thickener decide the properties of the grease. The amount of the thickener and its chemical composition define the consistency (NLGI grade). These NLGI grades start at 000 (fluid) until 6 (very hard).
oelheld supplies greases for several applications including:
- Multi-purpose grease for roller bearings and friction bearings
- Mineral oil based greases
- Gear grease
- Grease that is safe for food production
- Special greases for special requirements (heat resistant high-temperature grease, cryogenic grease and extreme pressure greases)
