Suitable for working areas that cannot be refueled or are difficult to refuel, with good wear resistance, low friction coefficient, and long service life; Good running performance, low noise, no pollution, and good corrosion resistance; The transfer film formed during operation plays a protective role on the grinding shaft, without any biting phenomenon; Low processing requirements for grinding shafts reduce user processing costs. In addition, OOB has developed high-speed self-lubricating bearings OOB10HP for fluid lubrication conditions such as gear pumps and plunger pumps. Under fluid lubrication conditions, the linear velocity can reach 10m/s, and the PV can reach 60N/mm2· m/s.
