The above-mentioned long Wrapped composite dry sliding bearing of the composite sliding bearing makes it suitable for use in high-speed heavy-duty, high-precision and infinite impact and vibration. The SOBBD bronze split type bush,cast 50SP2 guide bushing,rolling bearing can not be used as an operation, and the structural request is required to be split, and the radial dimension is required to be small and Work in water or corrosive media, as well as some simple support and unimportant occasions. On the key equipment of the main production line, for example, in the steam turbine, centrifugal compressor, internal combustion engine, rolling mill motor (high power), reducer, herringbone gearbox. Because of the widespread use, sliding bearing problems have become a common mechanical problem in steel companies. Grasping the operating principle, understanding the common types of faults and fault factors, adopting the method of fault detection for fault factors, and even carrying out daily protection according to the operating principle of bronze straight type guide bush oilless slide plate pad, composite sliding bearing to prevent the occurrence of defects, is a technical request that the mechanical repair personnel of the steel enterprise must reach.
