Flange slewing bearings are light in weight, thin in thickness, and flexible in movement. It is widely used in food machinery, filling machinery, environmental protection machinery, etc. The flange slewing ring bearing mainly includes outer and inner rings, grease fittings, sealing strips, gaskets, load plugs and taper pins, and its characteristics are: both the inner and outer rings are L-shaped; the sides of the rings are provided with grease cups, and the outer Steel balls are assembled between the ring and the inner ring. Each ball is separated by a spacer, and the steel ball and the spacer are installed through a load plug and a tapered pin to protect the running of the ball.

Ball and Roller Combination Slewing Bearing is mainly composed of an outer ring, an inner ring, rollers and steel balls. The inner ring and the outer ring each have a horizontal linear raceway and a spherical raceway, and the rollers are located in the horizontal In the linear raceway, the steel balls are located in the spherical raceway. The horizontally placed rollers bear the axial force, the radial force is borne by the steel ball, and the tilting moment is jointly borne by the both. It can not only bear large axial force, but also bear certain tilting moment and radial force, and has a small sectional size. This type of product is mainly used in construction machinery and equipment such as stackers and reclaimers.

Three-row roller slewing bearing has three seat rings, the upper and lower raceways and the radial raceways are separated. The upper and lower rows of rollers are arranged horizontally, and the middle row of rollers is arranged vertically. It can be made into an inner gear ring or an outer gear ring according to the equipment structure and work needs. The axial force and tilting moment in the two directions are borne by the upper and lower horizontal rollers, and the radial force is borne by the vertically arranged third row of rollers. According to the different characteristics of the load, the upper and lower rows of rollers can be of the same diameter or of different diameters. So that the load of each row of roller can be determined accurately. Being able to bear all kinds of loads at the same time, it is the largest one of the four structural products with large axial and radial dimensions and firm structure. It is especially suitable for heavy machinery requiring larger diameter, such as bucket wheel stacker and declaimer, wheel crane, marine crane, port crane, ladle turret and large tonnage truck crane, heavy machinery and so on.

Excavator is one of the important equipment in modern engineering construction. The reason why the excavator can turn left and right in the work is because of the slewing mechanism, which is one of the important components of the hydraulic excavator. The slewing mechanism is connected with the traveling device through a slewing bearing, and the slewing drive device makes the platform rotate relative to the traveling device, and drives the working device to rotate around its central axis of rotation. We are specialized in the production of engineering machinery slewing bearings, drive shafts and matched pinions. For some common model excavators slewing bearing, we have ready stock and can deliver within one week. Our company has a special quality testing laboratory, devoted to product design and development, product application and testing methods. At the same time, the company also has advanced production equipment and testing equipment to ensure that products have high performance, long life, low friction, high precision.
