Product Description
Product features:
Single row four point contact ball slewing bearings consist of a one-piece inner and outer ring and a set of spacers, protected by integral seals. The balls are inserted into the bearings via a hole in one of the two rings and are separated by polyamide spacers. After loading the ball set and spacers, the hole is closed with a plug that conforms to the race-way contour.
The single row four-point contact ball slewing bearings is divided into three series:- Light series four-point contact ball slewing bearings
- Medium size four-point contact ball slewing bearings
- Customized four-point contact ball slewing bearings
RKS.062.20.0744four point contact slewing bearing with internal gear teeth
Advantage: RKS.062.20.0644 four point contact slewing bearing with internal gear teeth, 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.
The three-row roller slewing bearing has three seat-rings,which separate the upper,lower and radial races,via which the load of each row of the rollers may be specified.It may bear different loads simultaneously and its load capacity is the largest one among the four models.
Thanks to the large size of its axle and radius,it is sturdy and especially suitable for heavy-duty machines which require large working radius.such a bucket wheel excavators , wheeled cranes, ship cranes, ladle turrets,heavy duty mobile cranes etc.Technical parameters:Part | Material | feature | |

Features | Slewing bearing is also called:Slewing ring bearing /Turnable bearing/Slewing ring etc. Slewing Ring Bearings can accommodate axial, radial and moment loads acting single or in combination and in any direction. They are not mounted in a housing or on a shaft, but directly to a seating surface. The inner and outer ring are supplied with mounting holes. Both rings may have integral gears. They are also referred to as slewing rings and tabletop bearings. Slewing ring bearing can perform oscillating (slewing) as well as rotating movements. They may be used without gears or with internal or external gear | |

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.
