The single-row four-point contact ball slewing ring bearing is composed of two races, with compact structure, light weight, and four-point contact between the steel ball and the arc raceway , 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.

Double-row reducing ball slewing ring bearing

The double-row ball slewing ring bearing has three races, steel balls and spacers can be directly discharged into the upper and lower raceways, according to the force In this case, 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. The axial and radial dimensions of the double-row reducing ball slewing ring bearing are relatively large and the structure is tight. It is especially suitable for loading and unloading machinery such as tower cranes and truck cranes that require medium or larger diameters.

Single row crossed roller slewing ring bearing

Single row crossed roller slewing ring bearing, consisting of two races, has a compact structure, light weight and high manufacturing precision. The assembly clearance is small, and the installation accuracy is high. The rollers are arranged in a 1:1 cross, which can bear axial force, tipping moment and large radial force at the same time. It is widely used in lifting transportation, construction machinery and military industry. On the product

Three-row roller slewing ring bearing

Three-row roller slewing ring bearing has three races, and the upper and lower and radial raceways are separated, so that each row The load on the rollers can be determined exactly. 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, port cranes, molten steel running table and large tonnage truck cranes and other machinery.

Light Series Slewing Ring Bearings

Lightweight slewing ring bearings have the same structural form as ordinary slewing ring bearings, light weight and flexible rotation. Widely used in food machinery, filling machinery, environmental protection machinery and other fields.

Single row four point contact ball slewing ring bearing

Single row four point contact ball slewing ring bearing consists of two races, compact structure, steel ball and arc rolling bearing Four-point contact. Mainly used in truck cranes, tower cranes, excavators, pile drivers, construction vehicles, radar scanning equipment and other machines that are subjected to overturning moment, vertical axial force, and horizontal inclination force.

Single row crossed roller slewing ring bearing

Single row crossed roller slewing ring bearing, consisting of two races, has a compact structure, high manufacturing precision and small assembly clearance , It requires high installation accuracy. The rollers are arranged in a 1:1 cross, which can bear axial force, tipping moment and large radial force at the same time. It is widely used in transportation, construction machinery and military products.
