Trailer slewing rings/slewing rings are widely used for heavy full trailers, light truck trailers, drawbar trailers, agricultural trailers, slewing rings for special vehicles and industry etc. used.

What characteristics does the ball bearing turntable of the trailer have?
Trailer Ball Bearing turntable is a kind of large bearing with special structure, which can carry large axial loads, radial loads and tilting moments as well as other comprehensive loads at the same time, integrating various functions such as support, rotation, transmission and fixation. Under normal circumstances, the turntable bearing itself is equipped with mounting holes, lubricating oil and sealing devices, which can meet the different requirements of different types of hosts operating under different working conditions. On the other hand, the trailer's ball bearing turntable itself has a compact structure, features such as easy rotation of the guide, easy installation and easy maintenance.
When the air is moist, the metal interacts with the oxygen and water it contains. Above the critical temperature condensation forms on the metal surface, resulting in corrosion. When the relative humidity reaches the critical humidity of the metal, the influence of temperature changes. Obviously, the reaction speed continues to increase with increasing temperature, resulting in corrosion of the bearing.
The special coating of the trailer ball bearing turntable can maintain the performance of the bearing. Although the equipment has a long service life by spraying a special paint or oxidation treatment on the outside surface, the usual method of rust protection is chrome plating or nickel plating.
1. Spacers for balls and rollers
The rolling elements are usually separated by separate spacers. This structure can maintain the suppleness of movement and is therefore often used. Special applications require special ball or roller spacers. Trailer ball slewing ring installed on the horizontal shaft or continuously rotating generator and bearings used in situations with high demands on positioning and reliability can use the strip-shaped combined cage to keep the rolling elements in the correct position. the peripheral position.
2nd gear
In many cases, gear teeth can be machined on the inner or outer raceway ring of the trailer's ball bearing turntable to simplify the construction of the drive system. To avoid problems, it is good to seek the help of an expert in gearboxes when determining the structure of the drive system.
3. The choice of connection method
The connection between the ball slewing ring of the trailer and the base and the rotating parts is mainly screwed. Therefore, the number, diameter, length, accuracy and, above all, the installation position of the bolts are very important. Not only the screw arrangements are different for different applications, but also the inner and outer rings are different.
