Light Series Slewing Ring Turntable Bearing
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 slewing ring 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 crane,excavators,bottling&packaging machine, robotsetc.
Structure
The slewing bearing can be made with internal gear, external gear and non-geared. Below are the structure for your reference.
Note:The thin section slewing bearing has the same structure with the ordinary slewing,but the weight is light,and rotate flexibly,which widly used in the food machinaery,canning machinery and environmental machinery etc.
Tytle:WD-231
Wight/KG:29-82.5KG
Strengths:The Oil nipple's location can be change according to the user's application.
Application:
1.food machinaery,
2.canning machinery
3.environmental machinery etc.
