Product Desciption

slewing turntable Slewing bearings are large-sized bearings which can accommodate a combined load, i.e., radial loads and tilting moment. They are usually provided with holes for fixing bolts; internal, external or no gear; and lubrication holes and seals, which allow a compact and economical arrangement. In additon they often enable the elimination of many components necessary in the classical bearing arrangement.  We select the bst bearing steel as our slewing bearing raw material,our forging supplier is the same as SKF of Sweden,TIMKEN of the U.S.Schaeffler(LUK/INA/FAG)of Germany,NSK of Japan from Jiangyin Xingcheng Special Steel Works Co.,ltd General:229-269HB:leadway;262-302HB The higher of the hardness, The better of the steel rigidity, So thr slewing bearing possess higher loading capacity therefore the longer service life In order to avoid excessive wear,high torque and stress concentrations. Leadway selects the best rubber seals on bearing to keep out debris and corrosion. Lubrication is another key to slewing bearing.when assembling,bearing are generally packed with a suitable grease for lubrication to reduce wear,and leadway use the better EP2 lithium grease.   FAQ 1.Q:Are you a factory or trading company?
