RKS.21.0541 L shaped slewing bearing with external gear Advantage:RKS.21.0541 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:We manufactures large diameter ball and roller bearings, and our slewing bearings have proven effectiveness in many applications such as below:
Access Platforms Amusement Rides Attachments Ballast Regulator Boomlift | Bridge Cranes Bucket Wheels Crane-Hook Rotators Concrete Pumps Construction Cranes | Deck Cranes Drilling Equipment Earth-Drilling Machines Excavators Emergency Vehicles | Floating Cranes Forklift Equipment Forest Machines Grapple Harbor Cranes | Logging Industry Machine Manipulators Mobile Cranes Offshore Cranes Packing Machines |
When slewing ring bearings are ready for shipment, Leadway usually give a light coating of
preservative oil and packaged in a tire wrap of protective paper and a shipping container.

4th: International Standard Wooden Case for by Sea or by Air 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.
This provides adequate protection during the typical short-term storage in a protected area
lewing bearing also known as slewing ring bearing,turntable bearing.It contain outer ring,
inner ring,rolling body,seals.The material of our products are generally high alloy-structural
steels ,such as 42CrMo 50Mn.The slewing bearing can work normally at a temperature of
-30ºC to +70ºC,and we can design special type as customer need.

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.
