Double-row Ball Slewing Bearing

¡òCLI Slewing Bearings are ball or cylindrical rollers that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction.
¡òThey are not mounted on a shaft or in a housing; The rings, which are simply bolted on the seating surface, are available in one of three executions:
¡ñ Without gears
¡ñ With an internal gear
¡ñ With an external gear
¡òCLI Slewing Bearings can perform both oscillating (slewing) movements as well as rotating movements.

¡òDouble-row ball slewing Bearing

The double-row Ball slewing bearing has three seat-rings. The steel balls and the spacers may be directly arranged into the upper and lower races. Two rows of steel balls with different diameters are fitted according to the force.
Such open mode fitting features extraordinary convenience. The load angles of both upper and lower races are 90°, which enables the bearing to bear large axial force and the tipping moment.
When the radial force is larger than 1/10 of the axial force the races should be newly designed.
As the axle and the dimension of the double-row ball slewing bearing are rather large, the bearing construction is sturdy ,hence it is especially suitable for tower cranes which require working radius over medium range, mobile cranes and loading and unloading.
