Yaw Bearing

designed the new structure of the PTFE fabric and improved the resin matrix. The new PTFE fabric has better wettability with the improved resin. Base on the new PTFE fabric and the improved resin we develop the high performance liner and TLtype bearings. Under the same condition, The new PTFE fabric liner has better bonding strength(2 to 3 times of the old one)and wear resistance(the service life is 3 to 4 times of the old one, . Meanwhile, the new PTFE fabric liner also provides the following benefits: low friction coefficient; low affinity to moisture,which provides water repellent properties; better resistance to deformation under load.

The role of variable rotor bearing is to rotate the blade installed on the hub, the outer ring is connected with the hub through bolts, and the inner ring is connected with the blade. When the wind speed is too high or too low, the Angle of attack of the airflow on the blade is changed by adjusting the pitch of the blade, so as to change the aerodynamic torque obtained by the wind turbine, so that the power output remains stable At the same time, the starting process of the fan also needs to obtain enough starting pitch by changing the pitch. The application environment of the bearing is bad, the diameter is small, the anti-overturning moment is large, the maintenance cost is high, and the high processing precision, zero clearance assembly and surface anti-corrosion treatment are usually adopted to ensure the high reliability and high life of the product.

wire race way ball bearing can sustain forces from whatever directions.The rings have the advantage that they fit themselves tightly into the bearing rings of the mating structure and compensate machining tolerances. With this technology high precision even if large bearing diameter is achieved. They are convenient and economical to use .The new process aimed at tightly matching between steel ball and race ways .Thus the load ,the capacity,and precision of the bearing elements are increased and they are better adapted to particular demands . There are four types of the wire race ball bearing:single row four point wire-race ball bearing,double row four point wire-race ball bearing,single row axial four point wire raceway ball bearing and hybrid type four point wire raceway ball bearing.wire-race ball bearings are ideally suitable for particular applications such as under clean room, high temperature ,or vacuum conditions .At the same time ,the customers can planned the particular bearings according to their requirements .We are rich in excellent experience and products series. Therefore, we are fully able to meet the customers requirements about the standard or non-standard.

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. Three types of this kind of double row different diameter ball slewing bearings:

single row four point contact ball slewing rings is composed of two seat rings, which design in compact structure and light weight, steel ball contact with the circular raceway at four points; it can bear the axial force, radial force and the tilting moment at the same time.Single-row four point contact ball ring has the features of compact in design, and light in weight. The balls roll on the circular race at four points, so it can undertake the axial force, radial force and tipping moment at the same time. This series of four point contact ball bearings are suitable in many engineering machinery, such as rotary conveyor welding operation machine, small cranes, small and medium-sized excavators,slewing conveyer, welding manipulator, light and medium duty crane, and other construction machinery Three types of this kind of single row four point contact ball slewing bearing: A. Without gear bearing (non tooth) B. External gear bearing (external tooth) C. Internal gear bearing (internal tooth)

A slewing bearing or slew[ing] ring (also called a turntable bearing) is a rotational rolling-element bearing that typically supports a heavy but slow-turning or slowly-oscillating loads in combination (axial, radial and moment loads), often a horizontal platform such as a conventional crane, a swing yarder, or the wind-facing platform of a horizontal-axis (yaw) windmill. In other orientations (e.g. a horizontal axis of rotation) they are used in materials handling grapples, forklift attachments, welding turnover jigs and so on.
