Large Diameter Yaw Extra Light Lightweight Slewing Ring Bearing for Tower Crane

5 0 Reviews

The four-point contact ball bearings are radial single row angular contact ball bearings featuring raceways that can handle axial loads acting in both directions. A limited radial load can be supported for a given axial load.

Quantity:
  • WD-061.20.0644F
  • Wanda
  • 8482800000

The light slewing bearing has the same structure with four point contact ball slewing bearing, but the weight is light and could be used for some light type machinery applications. It could save some cost if the load capacity is low. The light duty slewingring is low profile and has an excellent performance.

Applications:
It is used widely for the application of welding positioner slewing ring, medium and small series tower crane, excavators,bottling&packaging machine, robots etc.

Structure
The slewing bearing can be made with internal gear, external gear and non-geared. Below are the structure for your reference.The bearing capacity curve of light slewing bearing
Each type of slewing bearing of product samples hasa corresponding load-carrying capacity curve, and the graph can help the user to select the slewing bearing preliminarily.Comparing with other structure slewing ring, the weight of light slewing ring is light and could be used for some light type machinery applications. It could save some cost if the load capacity is low.

Light external gear slewing bearing consists of two rings (one inner ring and one outer ring.) It has compact structure and light weight. As its balls are four point contacted with the raceway, the slewing bearing can take axial load, radial road, and tilting moment at the same time.
The Light external gear slewing bearing slewing bearing has the same structure with the ordinary slewing,but the weight is light,and rotate flexibly,which widly used engineering machinery, construction machinery, metallurgy mining 


machinery, shipping port machinery, environmental machinery, light industrial machinery, petrochemical machinery, engineering vehicles, military devices, food machinery, canning nachinery, car parking systems etc.Since the light slewing bearing is so critical, careful maintenance is necessary. More than 96% of slewing ring bearing failures are due to surface-originated lubrication problems, contamination, overloading, and improper installation and mounting fits. These surface failures occur much earlier than classical fatigue failures and are less predictable.
