Slewing bearings are a large bearing capable of withstanding integrated loads and can withstand large axial, radial and overturning moments.
Rotary support, also known as turntable bearings, some people also called it: rotation support, swing support.
English name are: slewing bearing, slewing ring bearing, turntable bearing, slewing ring
Rotary support in the real industry is widely used, is known as: "machine joints", between the two objects need to be relative to the rotary motion, but also need to bear axial force, radial force, tipping moment of the machinery Essential transmission parts necessary. With the rapid development of machinery industry, slewing support in the ship equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries have been widely used.

The following slewing we can supply:
Double-row ball slewing bearing
Four point contact ball slewing bearing 
Cross roller slewing bearing 
Three-row roller slewing bearing 
Ball and roller combination slewing bearing 
Supply ability: can produce 8000 pieces slewing bearings per year.

Tapered roller bearings are widely used in gear drives and reducers, automotive front and rear axles, guide box in bar and rod mills, conveyor and transfer equipments and so on.

This bearing is suitable to bear composite load of axial load and radial load. Normally radial load is predominant but for great taper angle bearing the axial load could be predominant. 
Taper roller bearing is a separable bearing. Its outer ring can be mounted individually from the unit of inner ring, cage and rollers. Its radial and axial internal clearance can be adjusted during installation; even can be a interference installation. For taper roller bearing stamped steel cage is common selection. For large size bearing, welded steel cage or pin-assembled cage is used.
