Slewing Bearings

Crossed Cylindrical Roller Slewing Bearings

Crossed cylindrical roller slewing bearing comprises an inner ring, outer ring, single row roller, cage (gasket), and sealing device. Crossed cylindrical roller slewing bearings can bear axial load, overturning moment, and radial load at the same time. The design and application of the cross roller slewing ring are the same as the four-point contact ball slewing ring. The difference is that the rolling element is replaced from the ball to the roller, and the contact method between the rolling part and the ring is changed. Point contact becomes line contact. These changes increase load carrying capacity, but wear and friction moment loads also increase.

As one of the slewing bearings manufacturers, suppliers, and exporters of mechanical products, We offer slewing bearings and many other products.Please get in touch with us for details.

Applications of crossed cylindrical roller slewing bearing:

•Industrial robot arms, reducers

•Precision machines( turntable table)

•Rotation parts of Machine tools

•Medical equipment

• Measuring instruments

Slewing bearings application

Slewing bearings are widely used in large-scale slewing devices of hoisting machinery, mining machinery, construction machinery, port machinery, marine machinery, and high-precision radar machinery and missile launchers. At the same time, it can also design, develop and produce various special structure slewing bearings according to the specific requirements of users.In addition to various engineering machinery, the application range of slewing bearings has gradually expanded. Equipment platforms such as port equipment, metallurgical equipment, and drilling platforms have begun to use slewing bearings to replace original bearings on a large scale. For example the following…

  • Port equipment: port cranes, reach stackers;
  • New energy equipment: wind power equipment, solar power equipment;
  • Metallurgical equipment: metallurgical cranes, ladle turrets, steel grabbing machines, clay guns, oxygen blowing devices;
  • Amusement equipment: Ferris wheel, etc.;
  • Airport equipment: Airport refueling machine;
  • Military equipment: radars, tanks, etc.;
  • Robots: palletizing robots, welding robots, manipulators;
  • Medical equipment: gamma knife;
  • Environmental protection equipment: mud scraper;
  • Parking equipment: tower garage;
  • Drilling platform equipment, kitchen equipment, numerical control equipment (wire cutting machine, quenching machine tool), brick machine.
