Coresun are manufacturer of slewing bearing for many kinds of excavator. We only supply top quality slewing bearing and refuse to provide inferior products with low price to customer. All products produced by us have been certificated by the third party, product quality has been recognized by our cooperative partner.
As a key component in the structure of tower crane, slewing bearing plays an important role in the performance of tower crane.
In order to ensure the normal use of the tower crane, be sure to determine the relevant data so that technicians can design or recommend the most suitable slewing bearing.
The slewing bearing is widely used in the real industry. It is called "the joint of the machine". It is a mechanical device that needs to perform relative rotary motion between two objects, and also needs to bear axial force, radial force and tilting moment. Important transmission components required. With the rapid development of the machinery industry, slewing bearings have been widely used in marine equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.
double row different diameter ball slewing bearing is mainly made up of in-up ring, in-down ring and outside ring, so balls and spacers can be directly discharged into the upper and lower raceway. According to stress conditions, bearings are arranged to two rows of balls of different diameter. This assembly is very convenient. Angle of both upper and lower raceway is 90°so bearings can bear large axial force and resultant torque. Bearing needs special design when radial force is 0.1 times larger than the axial force. Large in sizes and features compact in design, bearings are particularly application in handling equipments requiring medium above diameter, such as tower crane and mobile crane.
single row cross roller slewing ring is mainly made up of inside and outside rings. It features compact in design, light in weight, small in assembling clearance, and high in installing precision. As the rollers are crossed arranged by 1:1, it is suitable for high precision mounting and capable to bear axial force, radial force and resultant torque simultaneously. This series single row crossed roller slewing bearing have widely application in lift transport aircraft, construction machinery, and mounted crane products.
