Calcium/lithium complex greases and encapsulated constant velocity joint containing the grease and method for their production
Embodiments of the invention include compositions of calcium/lithium complex greases containing calcium/lithium soaps having a high calcium fraction and complexing agents, encapsulated constant velocity shafts containing such lubricating greases and the use of the lubricating greases in encapsulated shafts of constant velocity shafts.
C10M 171/00 - Lubricating compositions characterised by purely physical criteria, e.g. containing as base-material, thickener or additive, ingredients which are characterised exclusively by their numerically specified physical properties, i.e. containing ingredients which are physically well defined but for which the chemical nature is either unspecified or only very vaguely indicated
C10M 169/02 - Mixtures of base-materials and thickeners
