RKS.21.0411 L shaped slewing bearing with external gear
Advantage:RKS.21.0411 L-shaped slewing bearing with external gear, it features compact in design, light in weight, high precision and small fitting clearance. As the rollers are 1:1cross arranged, it is suitable for high precision mounting and capable to bear axial force, resultant moment and considerable large radial force. The four point contact slewing bearing find widely application for transporting, engineering machines as well as for military products.Technical parameters:Stretch wrapping machines

Tadano Crane Slewing Bearing refered to slewing bearing used in Tadano Crane.
A slewing bearing or slew[ing] ring is a rotational rolling-element bearing or plain bearing that typically supports a heavy but slow-turning or slow-oscillating load, often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis windmill. (To "slew" means to turn without change of place.)
Compared to other rolling-element bearings, slewing bearings are thin in section and are often made in diameters of a metre or more; the slewing bearings on the Falkirk Wheel are 4 metres diameter and fit over a 3.5 metre axle. Slewing bearings resemble oversize aircraft control surface bearings.
Slewing bearings often use two rows of rolling elements. They often use three race elements, such as an inner ring and two outer ring "halves" that clamp together axially.

crane slewing bearing
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 doublerow 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.
