Definitions

  • This invention relates to a grease composition and to use of the grease composition in a sealed bearing.
  • seals prevent the ingress of dirt and water that could damage the bearing and impair the functioning of the machinery.
  • Typical seal materials include acrylonitrile-butadiene rubber (NBR) and
  • FKM fluoroelastomers
  • the present inventors have sought to provide grease compositions that can act to reduce the friction at the seal-metal interface and thereby improve the efficiency of sealed bearings.
  • the present inventors have surprisingly found that the combination of a low viscosity polyalphaolefin base oil with a calcium thickener can provide a grease generating particularly low friction at a seal-metal interface.
  • the present invention provides a grease composition comprising from 40 to 90wt% of a first base oil component which is a polyalphaolefin and having a kinematic viscosity at 100°C of between 1 and 5mm 2 /s, wherein the weight percentage is based upon the weight of the grease composition, and comprising a thickener which is a C13-C21 fatty acid salt of calcium.

  • the grease composition may comprise further base oils, but preferably the first base oil component makes up at least 50wt%, and preferably at least 80wt% of the total base oil (based upon the total weight of base oil in the grease composition) .
  • the thickener in the grease composition is a C13-C21 fatty acid salt of calcium, and preferably is a
  • the amount of thickener is preferably from 2 to 18wt%, based upon the weight of the grease composition, more
  • the grease composition of this invention may also comprise anti-oxidants, rust preventatives, oiliness agents, extreme pressure additives, anti-wear agents, solid lubricants, metal deactivators, polymers,

  • the rust preventatives include paraffin oxide, carboxylic acid metal salts, sulphonic acid metal salts, carboxylic acid esters, sulphonic acid esters, succinic acid esters, sorbitan esters and various amine salts.
  • the oiliness agents, extreme pressure additives and anti-wear agents include, for example, sulphurised zinc dialkyl dithiophosphates, sulphurised zinc diaryl dithiophosphates , sulphurised zinc dialkyl

  • the bearing will contain a lubricant and the grease composition of the invention should be applied such that the grease composition is not contaminated by the lubricant .
  • Greases were prepared by adding base oil and fatty acid to a kettle, heating to 85-90°C (at 3°C/min) and stirring at lOOrpm. Calcium hydroxide was added as a powder and then water was added. The kettle was closed and heated to 135°C (at 2°C/min) . The contents were stirred at lOOrpm and the wall temperature limit of the kettle was set at 140°C. The kettle was vented
