swing bearing

Three-row roller bearings can bear various loads at the same time. They have the largest load-bearing capacity among the four products. They have larger shaft and radial dimensions and a solid structure. They are especially suitable for heavy machinery requiring larger diameters.

Crossed roller slewing bearing is a key component commonly used in construction machinery and lifting equipment. It has the advantages of strong load-bearing capacity, flexible rotation and long service life. Crossed roller slewing bearing, referred to as slewing bearing, is a slewing bearing with rolling elements. Bearing, commonly used in construction machinery and lifting equipment. It realizes return through the rolling of rolling elements Rotating motion, bearing and transmitting loads, while having high stiffness and load-bearing capacity.

The three-row roller slewing bearing consists of three races, with upper and lower and radial raceways separated, so that the load of each row of rollers can be accurately determined. It can withstand various loads at the same time and has the largest carrying capacity among the four structural products. It has relatively large shaft and radial dimensions and a solid structure. It is especially suitable for heavy machinery requiring larger diameters, such as bucket wheel reclaimers, Wheeled cranes, port cranes, ladle rotary tables and large-tonnage truck cranes and other machinery.

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 inseparable from the credit 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.

Slewing ring is widely used in construction equipment like excavators. It is wear parts. We are specialized in the production of engineering machinery slewing bearings, drive shafts and matched pinions. If you need replacements of the steel balls, rollers or spacers, it is also available. For some common model excavators slewing bearing, we have ready stock and can deliver within one week. If you have old slewing bearing in hand, we can instruct you to measure the detailed size to make a professional drawing and then manufacture it for you.

The double row ball slewing bearing has three seat rings. The steel balls and isolators can be directly arranged 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 bearing angle of the upper and lower arc raceway is 75 degrees. It can bear a great deal of axial force and overturning 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 ball slewing bearing are relatively large and the structure is fastened. It is especially suitable for handling tower cranes, truck cranes and other loading machines that require medium or above diameters, military products. The double-row four-point contact ball slewing bearing structure is similar to the single-row ball slewing bearing, the difference is that it uses two rows of steel balls as rolling elements, the two rows of steel balls have the same size, and a single isolation block is set between the steel balls. The inner and outer rings are integral, and the steel balls are loaded by plugging the holes. It requires a product for a heavy-duty, radially constrained host. Double row different diameter ball slewing bearing structure is characterized by the upper and lower double-row steel balls, inner and outer rings, isolation blocks and lubrication and sealing devices. However, the double-row different diameter slewing bearing is a three-piece slewing bearing, and its structure is more complicated.
