Free lubrication bearing stiffness and the influence of roughness

Free lubrication bearings with high load capacity, impact resistance, high temperature resistant, self-lubricating ability etc., especially suitable for overloading, low-speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion.
Free of lubrication bearings products have been widely used in metallurgical continuous casting machine, rolling equipment, mining machinery, mould and hoisting machinery, textile machinery, wind power generation, shipping, steam turbine, water turbine, injection molding machine and equipment in the production line.Wear resistance is one of the common shaft sleeve.

Superior performance of free lubrication bearing materials:
1. High wear resistance, low wear rate
2. Lubricating, low friction coefficient
3. High impact strength, good toughness.
4. Excellent chemical corrosion resistance, resistant to almost all of the acid and alkali salt medium (except the sulfuric acid, concentrated hydrochloric acid, a few organic solvents)
5. Non-toxic, tasteless, no exudate
6. Elastic shock absorption;Good self healing, bibulous rate is extremely low
7. Good mechanical performance, can bear bigger impact with load, due to its excellent toughness, can effectively protect the rest of the parts from mechanical damage
8. Good low temperature resistance, even at 176 ℃ is not brittle.
Free of lubrication bearing aging from looking for reasons for this:
1.Because strong vibration motor iron core with fault caused by free lubrication bearing strong vibrations.Appear this kind of circumstance is to replace the same model of our new free lubrication bearing.
2.Cooperate with tight ball and slide clearance is too small, is the cause of torque, friction increases, the free lubrication bearing operating temperature is too high.
When installing so will try to adjust the correct lubrication bearing radial clearance.
3.Material fatigue due to metal fatigue, free of lubrication bearing raceway and the ball off the surface of the debris fall in the grease, led to the increase of noise.So we should consider the normal free lubrication bearing material fatigue, replace new bearing the same model.
4.Pollution, corrosion, check whether raceway and the ball surface corrosion appears red and brown punctate.
Free of lubrication bearing processing roughness: on the hardness and the influence of roughness, free of lubrication bearings and steel shaft processing roughness tend to increase in sliding sound, just without lubrication bearing material is soft, so the slide will make rough surface deformation and flat, as a result, it is not very big, the influence of the steel shaft material is hard, makeup rough surface, there is no change, and its influence is considerable.
