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; Due to the fact that the substrate is bronze, it has better corrosion resistance than other dry bearings compared to OOB-10.
