Slewing bearing

Double-row different diameter ball slewing bearing has three seats. The steel balls and the spacers may be directly arranged into the upper and lower raceways. Two rows of steel balls with different diameters are fitted according to the load. Such open mode fitting features extraordinary convenience. The load angles of both upper and lower races are 90°, which enable the bearing to bear large axial force and the overturning moment. When the radial force is larger than 1/10 of the axial force, the raceways should be especially designed. The axial dimension and radial dimension of double-row ball slewing bearing are rather large, and the bearing construction is sturdy. Hence it is especially suitable for tower cranes which requiring working diameter over medium range, mobile cranes and other unloading machines.

Wind power green renewable energy is inexhaustible. We design and manufacture of yaw and pitch bearings is an important part of the windpower equipment, they wind round to be able to easily rotate in thewind, and let the kinetic energy into electrical energy

Engineering and construction machinery is the most widely used areas of the slewing ring, such as tower cranes, excavators, cranes, and other kinds of construction crane, piling machines, concrete pump truck and so on. With China's rapid economic development of key national projects have been launched, a powerful implementation of urban infrastructure construction, engineering and construction

machinery heavy use of our products along with them all over in Chinaand around the world

Metallurgical and mining machinery, poor working conditions, high temperature, dust, such equipment for heavy equipment, to bear the

load of slewing ring. Three-row roller slewing bearings can work well in this case; the spherocylindrical Joint slewing ring made ??perfect use in the stacker-reclaimer

Medical CT is an indispensable part of modern medical equipment, slewing ring played a key role in medical CT machine. In addition, the slewing ring has a wide range of offshore equipment applications, such us offshore platforms, a variety of port cranes, deck cranes, etc. This type of slewing ring with high security and good corrosion resistance, sealing. Slewing ring high efficiency and reliability incoastal areas of the vast and enviable reputation
