Most favorable price : sales@hellerbearings.com
Prevent adhesion and formation of boundary lubrication performance when shaft and bearing direct contact . Friction affect material compatibility factors are:
( 1 ) the degree of difficulty as vice- material alloy metallurgy .
( 2 ) materials and lubricants affinity and capacity .
( 3 ) as Vice material without lubrication friction factor .
( 4 ) the microstructure of the material.
Thermal conductivity ( 5 ) of the material.
( 6 ) The surface energy properties of the material and the size of the oxide film .
2 embeddedness
Material allows external hard particles in the lubricant into the clamp and the ability to prevent scratching or ( and ) abrasive wear . Metal materials, low hardness and low modulus of elasticity , by embedding of the like, but not necessarily non-metallic material such as carbon graphite, low elastic modulus, but embedded bad. Slide FAG Bearings usually softer and harder material friction material pieces , usually done with a softer material bearing .
3 . Conformability
In the running-in process of the shaft and bearing , shaft and bearing to reduce processing errors , concentricity error , surface roughness parameters , the contact evenly, thereby reducing the ability of friction, wear rate .
4 Friction compliance
Material by plastic deformation compensation initial surface sliding friction surface and bend with poor performance. Low elastic modulus material better compliance .
5. Wear
Vice material resistance to abrasion . Under the specified conditions of wear , the wear rate or the degree of wear of the wear amount represents the reciprocal of the wear resistance .
6 fatigue resistance
Materials under cyclic loading resistance to fatigue failure . The use of temperature , strength bearing materials , hardness, impact strength and fatigue resistance organization against uniformity is very important . Run- resistance, and good embedding material, usually poor fatigue resistance .
7. Corrosion resistance
Materials resistant to corrosion. When using the oil gradually oxidized in the atmosphere to produce acids, and further containing at most extreme pressure lubricant additives , they will corrode materials FAG Bearing , therefore , FAG Bearing materials need to have corrosion resistance.
8 gas corrosion resistance
The movement of the solid to the liquid state, when the bubbles in the liquid in the vicinity of the solid surface rupture, resulting in partial or local temperature shock pressure will cause cavitation wear. Material resistance to cavitation wear is called cavitation resistance . Typically, the copper -lead alloy , tin-based FAG bearings zinc alloy and aluminum silicon alloy resistance to cavitation better.
9. Compressive strength
Ability to withstand the load without being squeezed bad way or size does not change .
