Slewing Bearings

Four-point Contact Ball Slewing Bearings

Four-point contact ball slewing bearing mainly consists of an inner ring, an outer ring, a row of steel balls, and a cage (or spacer). It has a four-point contact ball inner ring, and the outer ring has an integral and split structure. Four-point contact ball slewing bearing can bear axial load, overturning moment, and radial load at the same time. Almost all steel balls will bear the burden under the combined action of the axial load and the tilt moment load.

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.

Four-point contact ball slewing bearing mainly consists of an inner ring, an outer ring, a row of steel balls, and a cage (or spacer). It has a four-point contact ball inner ring, and the outer ring has an integral and split structure. Four-point contact ball slewing bearing can bear axial load, overturning moment, and radial load at the same time. Almost all steel balls will bear the burden under the combined action of the axial load and the tilt moment load. When taking a pure axial load, the steel balls are in contact with the raceways of the outer ring and the inner ring, respectively. When the radial load exceeds a specific value, the contact balls in the outer and inner raceway will have two points, respectively.

Factory

Applications of Four-point Contact Ball Slewing Bearing :

1. Slewing conveyor

2. Welding manipulator

3. Light and medium-duty cranes (truck-mounted cranes, deck cranes, aerial platform trucks, etc.)

4. Different excavators

Packaging and Shipping
1. Packaging
1) Packaging of commercial tapered roller bearings: 1 piece/plastic bag+color box+carton+tray;
2) Packaging of industrial tapered roller bearings: a): plastic tube + carton + pallet; b). Plastic bag +
Kraft paper+carton+pallet;
3) According to the customer’s requirements for tapered roller bearings

2. Payment:
1) T/T: 30% deposit. 70% should be paid before shipment.
2) L/C at sight. (high bank charges, not recommended but acceptable)
3) 100% Western Union in advance. (especially for air shipment or a small quantity)

3. Delivery:
1) Less than 45kg, we will send by express. (door-to-door, convenient)
2) Between 45 – 200 KGS, we will send by air. (fastest and safest, but expensive)
3) More than 200kg, we will send by sea. (cheapest, but takes a long time)

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.
