| | | X. LUBRICATION | | |
| | | |
| | | X. LUBRICATION Lubrication for linear rail system is a key part for its performance. The lubrication functions to reduce friction caused by frictional movement, so it reduces friction and take out the heat. Therefore, the right lubrication and right lubrication applying is critical for service life of linear rail system, | | |

Lubrication Preconditions For Linear Rail System Are As Follows: (D Form A Strong Oil Film © Have High Thermal Stability © Low-friction © Low-wear © Non-corrosive © Rust-prevention ©Oil Must Have High-viscosity And Grease Must Have Consistency Against Repeated Agitation of Grease. © High Conductivity For Heat. | | |

| | | Lubricants For Special Environments | | |
| | | |
| | | General grease can't be used for special conditions like continual vibration, clean room, vacuum, high and low temperature. If this is case, the appropriate lubricant should be selected. | | |

| | | Classification And Selection of Lubrication | | |
| | | |
| | | Operating Environment Lubricant Features Brand | | |
| | | Grease and Oil is representative of lubrication. Comparison of oil and grease for linear rail system is as shown in table 13. When selecting lubrication, consider its performance, use and purpose. | | |
