1. No need for oil supply device, oil filling machine, oil tank processing (oil supply device costs, processing costs, assembly costs and other excess costs and time savings, can greatly reduce manufacturing costs)
2. Reduction of operating costs (greatly reducing the use of lubricating oil and equipment maintenance costs, but also eliminating the risk caused by insufficient oil supply)
3. Shorten the design time (oil-free can greatly simplify the design, structure, etc., reduce costs, save design time, in addition, the use of self-lubricating bearings can also improve mechanical properties, extend service life and improve reliability and other aspects of remarkable results)
4. Lubricating oil recovery and environmental protection (no need to spend oil recovery treatment, conducive to environmental protection)
