Slewing Ring Bearings are often used indoors, and outdoors where exposure to moisture and significant contamination is possible. Normal temperature ranges -40°F to +140°F (-40°C to +60°C) are standard. Slewing rings designed to operate in harsher environments are available from Silverthin, contact a Silverthin Engineer early in your design process to identify the best bearing system solution for extreme environments.the correct service factor, often validated by testing.
The single row four point contact ball bearing is composed of two seat rings, which design is compact structure and light weight, steel ball contact with the circular raceway at four point, it can bear the axial force, radial force and the tilting moment at the same time.
It can be used for slewing conveyer, welding manipulator, light & medium duty crane, excavator and other construction machinery. engineering machinery: auto crane, excavator, tower crane; mining machinery: bucket wheel machine; metallurgy industry: clay gun, ladle turret, slewing mechanism of furnace cover. Besides, it is also applied to harbor machinery, welding machine, wind power generating set, medical device (CT machine), etc.
A fundamental mechanical part for the slewing motion of engineering machinery, mining machinery, building machinery and others. Four point contact ball bearing has functions of transmission of motion, load bearing and connection. Compared with the bearing, slewing bearing is in general applied to low speed and heavy duty.
Application field of external gear slewing bearing and introduction of typical application industry
Flanged external gear four-point contact ball thin type slewing bearing, has compact structure, light weight and flexible rotation. Widely used in food machinery, filling machinery, environmental protection machinery and other fields. Land leveler use slewing bearing, single row four-point contact ball with internal gear,it is thin and light weight, the special sealing structure has good sealing performance, High-aerial operating vehicle use slewing bearing,single row four-point contact ball with external gear, compact structure can bear axial force, radial force and tilting moment. British short teeth, has better gear bearing capacity, higher accuracy and the best reliability.
