1, no oil lubrication or less oil lubrication, suitable for non-refueling or difficult to refuel places, can be used without maintenance or less maintenance.
2. Sliding bearing has good abrasion resistance, small friction coefficient and long service Life.
3, there is an appropriate amount of elasto-plastic, the stress can be distributed in a wide contact surface, improve bearing Capacity.
4, the static friction coefficient is similar, can eliminate crawl at low speed, so as to ensure the precision of the machine Work.
