Lubrication is the control of friction and wear by the introduction of a friction-reducing film between moving surfaces in contact.
Many different substances can be used to lubricate a surface.
The Role of a LubricantTypes of Oil
The primary functions of a lubricant are:
- Reduce friction
- Prevent wear
- Protect the equipment from corrosion
- Control temperature (dissipate heat)
- Control contamination (carry contaminants to a filter or sump)
- Transmit power (hydraulics)
- Provide a fluid seal
