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,
General lubrication
Grease
Oil
Lubricant
Lithium-based Grease Calcium-based Grease Natrium-based Grease
Soap-based Grease
Lubrication Role:
® Reduce Friction And Wearing For Each Moving Part.
© Eliminate The Heat On Linear Rail System.
© Prevent Corrosion On Inside And Outside of Linear Rail System.
© Dust-prevention.
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.
Turbin Oil 1-4 Coolant Oil 1-3 Spindle Oil 1-2
Bentone-based Grease (High-temperature Grease)
Non-soap Based Grease
[table14]
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.
Vibrations
Easy oil film forming is required
CRG50 (NTG KOREA)
Clean Rooms
Low oil separation is required
High and Low Temperature
-40°O250°C
Vacuum
Water And Chemical Resistance Is Required
Vacuum Grease (Dow Corning)
Item Grease Oil
Rotation Low, Intermediate High
Seal Simple Cautious
Lubrication Change Complicate Simple
Life Short Long
Thermal Radiation Bad Good
Friction Torque Large Less
