What is the difference between metal gear grease and plastic gear grease?

July 07, 2022

Metal gear grease: high lubricity, high adhesion, durability and other properties are required. It is recommended to use gear grease produced from Synthetic Base Oil. The oil film is uniform and stable, and the durability is much better than that of mineral oil.

For all-metal gears, you can choose lubricating grease with higher viscosity, the thickness of the oil film will be thicker, and choosing the appropriate viscosity will allow better filling.

Grease for plastic gears: The outstanding feature is that there is almost no chemical and physical reaction with plastics, so it is necessary to have the necessary plastic compatibility test data, which is a basic performance requirement.

plastic gear grease

Since plastic gears and greases have certain compatibility problems, good plastic gear greases must be specially prepared for plastic products, and base oils with relatively high compatibility must be used.

There are several criteria to consider when selecting a grease:
①The working temperature can be divided into three states: high temperature, low temperature and normal temperature;
② When the adhesion gear rotates, it has a centrifugal effect on the grease, and the speed of the gear is proportional to the adhesion of the grease;
③ The load involves the selection of starting torque and anti-wear additives;
④ Low noise requirements;
⑤ Requirements for compatibility of plastic materials;
⑥Waterproof requirements;
⑦Environmental protection requirements;
⑧ Design life of lubricated parts.
