Light Type with Flange (WD-231) Rotary Conveyor Slewing Bearing with external gear
With Flange Light type slewing bearing
The light weight flange slewing bearing has the same structure as the ordinary slewing bearing, except that the cross section of the inner and outer rings of this type of slewing bearing is the 'L' type. The assembly height of such a slewing bearing is usually not very high. The light weight design makes the light weight flanged slewing bearing widely used in food machinery, filling machinery, and environmental protection machinery. In addition, our plant also upgrades and upgrades such products according to the needs of different users, so that the inner and outer rings are two sections respectively. Therefore, users can replace the slewing bearing spare parts without having to do a wide range of dressing on the main machine. This new slewing bearing is called NFB Harvard slewing bearing.
Flange bearing is a special slewing ring bearing, it can have one flange in the outer ring, or one flanged bearing in the inner ring, even it can have one flange in both inner ring and outer ring.
Structure
flanged ball bearing has three different types:
no gear
external gear
internal gear
With Flange Light type slewing bearing Application
Flange slewing bearings are widely used on tow trucks, and other applications are the same as trailer bearing, such as lifting & transport machinery, mining machinery, construction machinery, excavator, concrete machine, paper machine, plastic and rubber machine and steel plant.
