Oilless Bearing

High performance, low speed, low temperature, corrosive atmosphere, foreign material inflow, impact load and vibration, non-lubrication in the structure, or lubrication where it is ineffective even when lubrication is realized. It can be used as a bearing for high performance plastics, depending on the usage conditions, ranging from metals, copper, teflon and ceramics.

Using Field

  • Areas that cannot be refueled structurally and areas that are dangerous for.
  • Areas where products are contaminated or defective due to lubrication.
  • High and low temperature, (sea) underwater, chemical contact areas.
  • This is an area to prevent productivity decrease due to machine stoppage when refueling.
  • Fields that are ineffective even with refueling under severe use conditions such as stop bundle motion.
  • Shock and vibration field, high load, low speed motion field, green (blue) generation field, foreign substance penetration field.
  • SLIDING motion, angular swing motion.

Necessity

  • It is used for the parts where ball and roller bearing cannot be used because of various materials and shapes.
  • When refueling, it can prevent productivity decrease due to machine stoppage.

Pros and cons of Lubrication method

Dry lubrication (using solid lubricant) Fluid Lubrication (Lubrication or Water Lubrication)
Advantages – High speed low speed, reciprocating motion, impact load

-Angular swing movement, discontinuous stop bundle movement

-100% oil-free

-Corrosive atmosphere

-Low temperature-high temperature

-Light to heavy load, high speed rotation

(Fluid Lubrication = Lubrication Oil Film Formation)

Disadvantages – Not available for high speed (Low speed principle)

-High oil pressure, high friction coefficient

Friction may occur when used.

-No use at high or low temperature

-Regular refueling required

-Oil film can not be formed under high load

-No corrosive atmosphere

-Impact movement, angular swing movement and non-stop fastening
