1、  Removing of Feed Oil Device:
     Feed Oil Device involve widely feed oil hole, oil pump, saving oil groove and pipe. The price, installation and cost of processing feed oil hole in the axle and oil groove for bearing make Feed Oil Device more expensive than using Self-lubricating bearing.
2、  Saving lubricating oil
      The factory with many machines use a large number of lubricating oil every year. Fr example, 80 thousand KM waterwheel use 100kgs lubricating oil at least every year, if Self-Lubricating Bearing is taking, the waterwheel can reduce the use of lubricating oil greatly and save maintenance cost, management cost and energy.
3、 Saving maintenance cost
      The feed oil-inspecting meter of textile machine must be often maintained, after taking Self-lubricating bearing, the maintenance can be avoided and the trouble caused by using Feed Oil Device can be prevented
4、 Recyde of lubricating oil and protecting environment
      When feeding lubricating oil, the sprayed oil pollutes the factory environment and water. Now, the cost of recycling wasted oil has increased greatly, by taking Self-Lubricating Bearing, environment is protected and recycle of lubricating oil is saved.
5、 Reducing design cost
      By taking Self-Lubricating Bearing , the design of feed oil system(feed oil hole, feed oil pipe oil device) can be omitted, at the same time, the standardizing of Self-Lubricating Bearing, further lower the design cost.
6、Simplifying machine structure
      By taking high load capacity Self-Lubricating Bearing, feed oil device can be removed, and bearing, bearing base and axle can be Simplified, so the machine is more compact and cost is reduced.
      Except for the points mentioned above, the friction resistance ability of self-Lubricating can longer machine life, maintain machine precision and saving machine assembling time.
