01 Series
The single-row four-point contact ball slewing bearing is composed of two races, with compact structure, light weight, four-point contact between the steel ball and the arc raceway, and can withstand axial force, radial force and tipping moment.
02 Series
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.
11 Series
The single-row cross-roller slewing bearing has a compact structure, high manufacturing accuracy, and high requirements for installation accuracy. The rollers are arranged in a 1:1 cross, and are widely used in construction machinery.
13 Series
The three-row roller slewing bearing is composed of three races, three groups of rollers and spacers. The upper and lower rows of rolling elements bear axial force and overturning moment, while the lateral rolling elements bear radial force.
22 Series
The ball-column slewing bearing is mainly composed of an outer race, an inner race, rollers and steel balls. The horizontally placed rollers bear the axial force, and the radial force is beared by the steel balls.
23 Series
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.
Double Worm Series
Double worm slewing drives are combined by Housing, slewing ring, two hourglass worm and some Matching parts, it achieved 2 times of tooth contacting. In the same volume and installation space, it improved nearly double output torque, greatly improving the product's performance.
Enclosed Housing Series
The enclosed housing slewing drive is composed of the fence type base, slewing bearing, enveloping worm and the completed spare parts. The Electronic motor and hydraulic motor can be all used as the power input source for slewing drives, which can make clockwise and counter clockwise rotation.
Opened Housing Series
Open housing slew drive mainly apply to the lower working condition, such as no high requirement for the dust-proof, rain-proof and anti-corrosion. It was widely used on aerial platform vehicle and truck crane. The open housing slewing drive can reduce the cost compared with the enclosed housing slewing drive.

Slew bearing catalogue
The catalog of FH slewing bearings contains thousands of standard models, and we also focus on the research and development of non-standard slewing bearings. What is a slewing bearing? Slewing bearings can be divided into many different types according to their different structural forms
5 Steps to Testing an Excavator Slewing Bearing
The slewing ring is an important part of the excavator. There are internal teeth and external teeth, and the size is different. It mainly depends on the tonnage. The 8T generally uses a slewing ring of about 760mm. The external teeth are mainly used for truck cranes, tower cranes, excavators, Pile drivers, construction vehicles, radar scanning equipment. How to detect the excavator slewing bearing?
How to choose a suitable slewing ring gear?
When designing pinion teeth, one of the important parameters is the modulus. The meshing of the gears produces the pulsation of the meshing, which is caused by the elastic deformation of the deformation of the gear teeth. As one of the basic parameters for designing gears, the modulus of the gear (if large) (that is, the size of the gear is large) has a relatively large load capacity.
How to calculate the friction force of slewing bearing？
In fact, slewing bearings, like many other mechanical equipment, need to be calculated and designed when they are used. Because it is mainly bearing capacity, the calculation of its friction moment and so on needs to be very rigorous. Friction torque: the product of the friction force and the friction arm. The friction arm is the nominal radius of the bearing. Before determining the magnitude of the friction force, determine whether it is static friction or sliding friction, because the calculation methods of the two friction forces are different.
