introduction： Multiple bearing[bearing:bearing（“Bearing”，Japanese person“Axial receptor”）It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said，When other parts move relative to each other on the shaft，A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]The bearing steel used by enterprises is not good enough，Even some inferior bearing steel，This leads to the production of low bearing products，likeTIMKENBearing such a production enterprise is not the same，The bearing steel used is all quality

introduction：Used to control liquid pressure in hydraulic transmission、Flow and direction elements。The pressure control valve is called the pressure control valve，The flow control valve is called the flow control valve，Control pass、The break and flow direction are called directional control valves。 Pressure control valves are divided into relief valves according to their use、Pressure reducing valves and sequence valves。①Overflow valve：Can control the hydraulic system to maintain a constant state when reaching the set pressure。Relief valves for overload protection are called safety valves。When the system fails，When the pressure rises to a limit that may cause damage，The valve port will open and overflow，To ensure the security of the system。②Reducing valve：Energy control fraction
