Single row ball slewing bearing

The single-row four-point contact ball slewing bearing is composed of two races, with compact structure and light weight. The steel ball is in contact with the arc raceway at four points, and can bear axial force, radial force and tipping moment at the same time. Construction machinery such as rotary conveyor, welding manipulator, small and medium-sized crane and excavator can be selected.

Single row cross roller slewing bearing

The single-row cross-roller slewing bearing consists of two races, with compact structure, light weight, high manufacturing precision, small assembly clearance, and high requirements for installation accuracy.

Force, tipping moment and larger radial force are widely used in lifting and transportation, construction machinery and military products.

Double row ball slewing bearing

The double-row ball slewing bearing has three seats, and the steel balls and spacers can be directly discharged into the upper and lower raceways. According to the stress conditions, two rows of steel balls with different diameters are arranged. This kind of open assembly is very convenient, and the bearing angle of the upper and lower arc raceways is 90°, which can bear a large axial force and tipping moment. When the radial force is greater than 0.1 times the axial force, the raceway must be specially designed. 

Three-row roller slewing bearing

The three-row roller slewing bearing has three races, and the upper and lower and radial raceways are separated, so that the load of each row of rollers can be accurately determined. It can bear various loads at the same time, and is the one with the largest bearing capacity among the four products. The axial and radial dimensions are large and the structure is firm. It is especially suitable for heavy machinery requiring large diameters, such as bucket wheel excavators, wheel Cranes, marine cranes, and large tonnage truck cranes and other machinery.

Light slewing bearing

Light slewing bearings are divided into flange type and thin type. These two types of slewing bearings can be subdivided into gearless, external gear and internal gear slewing bearings.
The light slewing bearing has the same structural form as the ordinary slewing bearing, with light weight and flexible rotation. Widely used in food machinery, filling machinery, environmental protection machinery and other fields.
