1. Descriptions:
The single-row four point contact ball slewing ring is composed of 2 seat-rings.It features compact in design,and light in weight.The balls contact with the circular race at four points,via which the axial force,radial force and resultant moment may be born simultaneously.
The single-row four point contact ball slewing ring has internal gear,external gear and non-gear.
2. Application:
This series of four point contact ball bearings are suitable in many engineering machinery, such as rotary conveyor welding operation machine, small cranes, small and medium-sized excavators and more.
3. Delivery lead time:
In-stock product in 7 days
Standard product in 30 days
Customized product in 40-60 days
Package: three layers in wood cases
Transportation types: by sea, by air, by courie
4. Materials:
Materials of rings and rolling parts
Generally, DRE uses carbon-chromium bearing steel GCr15SiMn or GCr15 for rolling parts and surface-hardened steel 50Mn, 42CrMo, 5CrMnMo for the rings
Material of cages
The cages for DRE slewing bearings include integral cage, segment cage and spacer-type cage
We use 20# steel or ZL102 birmasil for integral and segment cages, PA 1010 resin or ZL102 birmasil or QA110-3-105 albronze for spacer-type cages
In recent years with continuous development of material industry, nylon GRPA55.25 started to be applied for segment cages
Material of seals
Generally, DRE uses NBR or VITON for seals
But there still very few slewing bearings DRE manufactured in early period sealing with felted wool
5. Normally we have structure as below:
Single-row four point contact ball slewing bearings
Single row cross roller slewing ring bearings
Double-row ball slewing bearings
Three-row roller slewing ring bearings
We can also supply other types as customers require, if you have any type not listed above, please contact us to see if we can make the production
