Effective lubrication of rolling bearings can extend maintenance intervals

With increasing installed power, there is a trend towards larger and larger bearing turbines. The most commonly used main rotor shaft bearing is a special double-row tapered roller bearing with an outer diameter of nearly 2.4 meters. Because the bearing is large and the installation is laborious, it is necessary to do smoothing operations at one time, and reduce the number of smoothing again as much as possible. The company selects corrosion-resistant, high- and low-temperature-resistant smooth grease to fill the bearings, and uses double-sided sealing technology to prevent leakage of the smooth grease.

　　 Rolling bearings in wind turbines are often subjected to harsh operating conditions: engine bearings must accept high oscillating stress, while roller bearings in other applications face extremely high loads and vibrations. In order to satisfy the application requirements of this category, it is necessary to choose high-quality smooth grease. The formulation of smooth grease must be satisfied that wind turbines can ensure stable operation even in harsh environments and have a wide range of operating temperatures. Moreover, even during the strike period, the smoothing agent can effectively ensure that the parts will not rust.
