Single row cross roller slewing bearing

Single-row cross roller type rotating support, composed of two seat rings, compact structure, light weight, high manufacturing accuracy, small assembly gap, high requirements for installation accuracy, the rollers are separated by 1:1, which can bear force and deflection at the same time Radial force and tipping spiral. It is widely used in lifting and transportation, construction machinery and military products.

Single-row four-point contact ball slewing bearing

The single-row four-point contact ball bearing rotating support consists of two seat rings, compact structure, light weight, four-point contact between the steel ball and the arc raceway, and can bear the bearing force, radial force and tilting coil at the same time. Conveyors, welding manipulators, small and medium cranes and excavators and other construction machinery are replaced.

Therefore, the load of each row of rollers can be correctly aligned and determined, and can withstand various changes at the same time. It is the largest load-bearing capacity of a certain product. The axial and radial dimensions are both strong and axially structured, especially suitable for fracture. Diameter heavy machinery, such as bucket wheel excavators, wheel cranes, marine cranes, ladle rotation and large tonnage truck cranes and other machinery.

Double row angular contact ball slewing bearing

The double-row ball type rotating support has three seat rings, and the steel balls and spacers can be directly discharged into the upper and lower raceways. According to the stress conditions, the upper and lower rows of steel balls with different diameters are arranged.

This kind of open assembly is very convenient. The load-bearing angles of the upper and lower arc raceways are both 90°, which can bear a large incident force and tilting torque. When the radial force is greater than 0.1 times the insertion force, the raceway should be specially designed. The double-row ball slewing bearing has relatively large axial and radial dimensions and a strong structure, which is especially suitable for loading and unloading machinery such as tower cranes and truck cranes that require medium or larger diameters.
