Multi-purpose greases are recommended for most maintenance applications where the temperature remains within a conventional range of -20°C to 130°C. Load, speed and lifetime constraints also remain within standard values.
Multi-purpose greases are called traditional or conventional greases. They are recommended everywhere when constraints remain “moderate”. Mostly offered in NLGI2 grade, the most versatile: The archetype being EP2 Grease. These are the greases with the best price/performance ratio and they have proved their worth over a long time.
As their name indicates, they are very versatile. They are suitable for all types of general lubrication. Targeted additives and the know-how of manufacturers-formulators have nevertheless made them very good challengers for speciality greases.
They cover all application fields, or nearly all, and are available in all sorts of packaging:
from the 400g cartridge, which remains the most common small format
up to 190kg drums
According to the industry, these multi-purpose greases can be offered in boxes, buckets or kegs and also aerosols and automatic greasers.
Applications
Multi-purpose or multi-functional greases are particularly suitable for lubrication of equipment such as:
Axles and articulations
Gimbals, chassis
Pipes (for their protection)
...
Characteristics
Multi-purpose greases can be made of calcium soaps (hydrated or anhydrous) but more generally they are made of a lithium soap. This chemistry is particularly stable and resistant to mechanical constraints.
