We can produce flange slewing bearings that satisfy European customers is because we have mature flange processing technology. Generally speaking, our product raceway hardening treatment is intermediate frequency quenching and the large internal stress generated by temperature difference fusion cannot eliminate internal stress due to the large size of the flange but small cross-sectional area, resulting in excessive deformation.

Five Things to Prevent the Excavator Turntable Bearing from Making Noise The slewing bearing can also be called a slewing ring bearing, and most people also call it a China slewing ring. Just like the slewing bearing on an excavator, it is often called a slewing bearing. The slewing ring is a large bearing that can bear comprehensive loads, and can bear large axial and radial loads and overturning moments at the same time. Mini digger slew ring bearings generally have mounting holes, internal or external gears, lubricating oil holes and sealing devices, so that the design of the main engine can be compact, easy to guide, and easy to maintain.

Cross Roller Slew Bearing is with rolling elements in a 90°cross arrangement at a ration of 1:1. Due to the roller transmit load in a single direction, and the contact area of roller is bigger than the ball, so the rotational torque is less than a ball type design, it can provide higher rigidity and strength. Although the crossed roller slew bearing is with less load capacity than ball type when with same size rolling elements, but crossed roller type bearing has higher stability. SWBTEC can produce different size crossed roller slewing bearing with dimension from 100mm-2500mm and often prepare stock for popular model.

Single Row Ball Slewing Bearing is with the same structure with four point contact ball type-the ball and raceway are 45° contact, due to it has good stability and high cost performance, it has been used widely in many equipment, like excavator, crane, aerial work platform. etc. our normal production is mainly for this type. we have optimized the design contact angle, raceway quenching depth and hardness of single row ball slewing bearing to make our slewing bearings have longer service life.

SWBTEC slewing ring with stable quality has been used in many kinds of applications, with the development of the time, our slew bearing is serving at the most corners of the earth, they including truck crane, welding robot, parking equipment, airport ferris wheel, ship crane, aerial platform vehicles, etc. Slew Ring For Water Treatment

Customized Slewing Bearing, From special material to special structure, also special grease which need to bear high or low temperature, special seal ,special spacer, SWBTEC can design whatever size and produce according to your supplied drawing.please feel free to contact with our sales person,SWBTEC technical advantages plus high quality control standards and production capacity can meet your any requirement.

Due to Four point contact ball slewing bearing has the widest application, it is our main product and account for 80% of the total product, In order to make sure the contact angle is within the right point, we constantly inspect the raceway grinding machine and inspect the contact angle with a special tool which is our practical patent, this is also why our delivery slewing bearing has longer life than other peers.

Crane Slewing Bearing, In order to meet customer requirement for the growing product range, our engineer often go to the customer company to measure the old sample and make drawing accordingly. we can also do some change as customer special requirement, like increase ball size to increase the load capacity.SWBTEC can produce crane swing circle with good quality and long service life.

High Precision Cross Roller Slewing Bearing can bear axial, radial and tilting moment load from different directions due to the roller inside is arranged vertically and in a 90°V groove. This design can minimum the dimensions of inner ring and outer rings and make the bearing with high rigidity and high precision which can reach to P5, P4, P2, so it is the optimal choice for applications such as industrial robot, rotator, precision rotary table, medical equipment and military equipment.

When there is no load or pure radial load, the steel ball makes four-point contact with the bearing ring, which is also the origin of the name. When there is only pure axial load, the steel ball makes two-point contact with the bearing ring, which can withstand two-way axial load. The four point contact ball bearing slewing ring can also bear torque loads and has the functions of single-row angular contact ball bearings and double-row angular contact ball bearings. Four point contact ball slewing bearing can only work properly when forming the two-point contact between steel ball and bearing ring.

In the process of slewing bearing use, it will endure 3 different direction force, including the axial force Fa, the radial force Fr and the overturning moment M. The combination of the three loads will change as a result of different working ways and different structural types in different practical applications, sometimes it may be bear two loads, sometimes there is just one load. This requires the slewing bearings to have high stability of quality, SWBTEC slew bearing, from raceway hardening to gear hard treatment, we strive to excellence.
