Slewing bearings are also called turntable bearings, rotating bearings, and slewing ring bearings. They are large bearings that can withstand combined loads (withstand large axial, radial loads, and overturning moments at the same time）, so they are applied in a variety of applications. The slewing bearing has a simple installation and upkeep process. Its design is space-efficient, with seals on both sides. And you can add grease through a special nozzle to lubricate the slewing bearings.
There are many types of slewing bearings, and four-point contact slewing bearing stands out as a common type among slewing bearings. It can handle heavy loads.
The four-point contact ball slewing bearing has a straightforward structure. It includes an outer ring, an inner ring, steel balls (rolling elements), spacers, and seals. The inner and outer ring raceways have two arc grooves. When the steel balls move in these grooves, they touch the inner and outer rings at four points. This four-point contact lets it withstand different loads at once, including axial, radial, and overturning forces. This design works well for equipment with medium loads and slow speeds. They can be used in tower cranes, construction gear, port machines, and diggers, etc.
The most common type in four-point contact ball slewing bearings has a simple structure and low manufacturing cost, usually used for equipment with medium loads and low speeds.
Having a stronger load-bearing capacity than single-row bearings, and works well in applications with large loads and high rigidity.
Mainly designed to divide the inner ring or outer ring of the bearing into two parts. Facilitates the bearings' installation and removal, and is suitable for where frequent maintenance is required.
Gearless structure, able to carry loads from different directions. But cannot directly transmit torque, if required to do that, this type of bearings needs to cooperate with external transmission devices such as motors or gearboxes to achieve rotational motion. It is commonly used in applications such as some automation equipment, rotary workbenches, etc., with high load-bearing requirements but no transmission function.
Gears are designed on the inner ring, they are meshing with the gears of the internal drive system. The internal gear four-point contact ball slewing bearing can save external space and reduce the interference of the external environment on the gear. It is good at equipment with compact space and high transmission accuracy requirements, such as tower cranes, excavators, and joints of some industrial robots.
The external gear design arranges the gear structure on the outer ring and directly meshes with the gear of the external drive system. And are easy to maintain and replace. They are useful for equipment such as large cranes, construction machinery, wind turbines, etc., with larger spaces.
The non-standard customized four-point contact ball slewing bearing, as its name suggests, is designed to meet specific special application needs. Customers have the option to tailor the size, material, raceway structure, and gear form, among other features to make the bearing to suit particular working conditions or equipment specifications.
(1) Simple structure, low manufacturing cost, and easy installation.
(2) Multi-directional load-bearing capacity, able to withstand axial, radial, and overturning moments at the same time, especially suitable for complex load situations.
(3) Have stronger load-bearing capacity under medium load conditions compared to other types of slewing bearings
