Slewing Bearings

Three Row Roller Slewing Bearings-1

Three Row Roller Slewing Bearings

Three-row roller slewing bearing has three seat rings; the upper and lower raceways and the radial raceways are separated so that a load of each row of roller can be determined accurately. Being able to bear all kinds of limitations simultaneously, it is the largest one of the four structural products with large axial and radial dimensions and firm structures. It is especially suitable for heavy machinery requiring larger diameter, such as bucket wheel stacker and reclaimer, wheel crane, marine crane, port crane, ladle turret and large tonnage truck crane, heavy machinery, and so on.

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.

Design Features

The three-row roller slewing bearing has three rows of independent rollers, the direction of which is perpendicular to the direction of the load transmitting, the top and bottom rollers holding the axial load, and the middle roller loading the radial load.

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.
