Benefits

• Reduced costs through superior protection, longer grease life and simplified maintenance and inventories
  
  
• Longer component life from superior corrosion and wear protection
  
  
• Longer grease life through excellent mechanical stability and controlled oil separation
  
  
• Peace of mind from a grease with more in-service hours than any grease in its class

Simpler and safer maintenance

 The logistics of stocking greases for varied aircraft applicationscan be complicated. With numerous products, it is easy forthe wrong grease to be used. An unsuitable grease may fail toprotect components adequately and may even be unsafe. 

To simplify maintenance and reduce product-misapplication risk,Boeing created its BMS 3-33 specification. A grease meetingthis standard would replace a range of greases, and extendcomponent life and lubrication intervals. 

Following a testing period by Boeing, AeroShell Grease 33was the only product to meet all the requirements of the originalBMS 3-33 specification. It can be used on all but 9 of the359 grease application points on a Boeing 737. This greatlysimplifies the maintenance of this and many other aircraft andenhances safety by reducing the risk of product misapplication

Protecting components from wear

AeroShell greases can help to extend component life and reduce maintenance costs by preventing wear and corrosion. For example, in industry tests, AeroShell Grease 33 showed

• A smaller wear scar in a wear test than a MIL-PRF-81322Gspecification
  grease4
• No corrosion in saline solution, whereas a bearing with MILPRF-81322G-specification
  grease showed corrosion between the rollers and the race.

Its partner, AeroShell Grease 64 (formerly AeroShell Grease 33MS) is designed to provide similar benefits for the protection of heavily loaded sliding surfaces such as the bogie pivot pins on landing gear assemblages. It contains 5% molybdenum disulphide for exceptional load-carrying and extreme-pressure performance.

Please Note: AeroShell Grease 33 contains a synthetic oil and must not be used with incompatible seal materials.
