Introduction of oil seals

The oil seal is a customary term for general seals, which is simply a seal of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system, and also generally refers to the general liquid substance). It isolates the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubrication Oil leakage. Seals for static and dynamic seals (generally reciprocating) are called oil seals.

Common materials for oil seals are: nitrile rubber, fluororubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc.

Oil seals are required wherever there is liquid lubricating oil in the running body box and it is connected to the outside. Some are rubber, some are metal, and most are steel-bonded rubber, such as the rear crankshaft oil seal, front and rear gearbox oil seals, left and right half shaft oil seals, main reducer front oil seal, air compressor crankshaft oil seal, etc.

Production Process

The manufacturing process of the oil seal is more complicated. We take the rotary class as an example to explain the process flow of the oil seal and explain which process flow will use our equipment.

Process flow

The following process will use our equipment

  • Pre-processing equipment: Automatic phosphating line


  • Glue spraying: Automatic glue spraying machine

Industry pain points



  • The utilization rate of hand-sprayed glue is less than 20%, and the cost of glue is high

  • The thickness of the manual glue is uneven, and the production efficiency is low

  • Manual loading and unloading of products, high labor costs

  • The traditional method of gluing and drying covers a large area and the cost of the workshop is high

  • The traditional glue dipping method occupies a large area and consumes a lot of energy.

Product requirement




Our advantage



  • We use the method of roll spraying, the utilization rate of glue reaches more than 90%

  • Uniform film thickness, precise thickness control

  • High degree of automation and safer operation


  • Small footprint, low energy consumption and high production efficiency

  • Fully-enclosed coating, the dust is precisely filtered to ensure no pollution in the workshop

  • Accurate flow control, automatic alarm when blocking gun
