230.20.0400.013 Type 21/520.0 is slewing bearing with Flange.
It composed of two seat rings, compact in structure and light in weight. The steel ball is in contact with the
arc raceway at four points and can bear axial force, radial force and overturning moment at the same time.
The slewing bearing be produced as your demands,
1 Offer the size for us, our technicist will design the bearing
2 Offer the type for us, If that is standard, we can produce directly
3 Offer the drawing for us, we can produce as the same as the drawing.
Advantages:
It can take axial load, overturning moment and radial load at the same time. Under the combined action of axial load and overturning moment, almost all steel balls participate in the load. When bearing pure axial load, the steel ball and the inner and outer ring raceways are in single-point contact. When the radial load exceeds a certain value, the steel ball and the inner and outer ring raceways respectively have two points of contact. At this time, the wear and friction torque will increase. In order to cope with the different combinations of axial force, overturning moment and radial force generated under various working conditions, the contact angle can be adjusted accordingly.
Application:
– Excavators
– Drilling rigs
– Mining Equipments
– Cranes
– Offshore Equipments
– Vehicles
– Machine Tools
– Wind Turbines
Other Slewing bearing:
• Single row four point contact ball slewing bearing
• Single row crossed cylindrical roller slewing bearings
• Double row ball slewing bearings
•Double row Roller/ball combination slewing bearing
