Slewing Bearing description
A slewing bearing or slewing 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 metre 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.
Slewing bearings are often made with gear teeth integral with the inner or outer race, used to drive the platform relative to the base.
As for other bearings that reciprocate, rather than rotating continuously, lubrication can be difficult. The oil wedge built up in a continuously rotating bearing is disrupted by the stop start motion of slewing. Instead, a hydrostatic bearing with pumped oil flow may be used.
Application of Slewing Bearing:
Excavator Slewing Ring,Crane Slewing Bearing,Construction Machinery Slewing Bearing,Wind Turbine Bearing,Ladle Turrent Slewing Bearing,Ferris Wheel Slewing Bearing

The slewing bearing is a basic mechanical component for engineering machinery, mining machinery, construction machinery and other machineries that require relative rotary motions of two parts. The slewing bearing serves to transmit movement, bears load, and connect. However, different from bearing applications, the slewing bearing is generally suitable for low speed and heavy load.
The slewing bearing has a wide range of applications including engineering machinery, e.g. truck crane, excavator, and tower crane; mining machinery, e.g. bucket wheel machine; metallurgical industry, e.g. clay gun, ladle turret, furnace cover slewing mechanism, etc. It is also used for port machinery, welding machinery, wind power generating equipment, medical equipment, e.g. CT machine, etc.
Slewing bearing is one of our main products.
1. four point contact ball slewing bearing (no gear, external gear, internal gear);
2. two row ball slewing bearing;
3. crossed cylindrical roller slewing bearing;
4. three row cylindrical roller slewing bearing;
5. crossed tapered roller slewing bearing;
6. ball and roller combined slewing bearing.
With advanced science and technology, the company develops and manufactures various kinds of bearing products with inner diameter of over 100 mm according to the national standard,such as large-size and extra-large-size deep-groove ball bearings,angular contact ball bearings,single,double and four-row cylindrical roller bearings,spherical roller bearings,single,double and four-row tapered roller bearings,spherical ball bearings,thrust ball bearings,thrust roller bearings,slewing bearings,and split bearings,the products are widely used in the fields all over the country, such as port,machine tools,mining,metallurgy,power industry,medical,heavy machinery,coal machinery,cement machinery,petroleum exploration as well as national defence industry.With the right to handle the export.

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.
