Wind turbines currently mostly adopt a double-row ball four-point contact ball bearing structure to meet the varying demands of different wind speeds on the blade angle. In recent years, the reliability problems caused by simple and rude increase in blade length even cannot be avoided by mainstream equipment manufacturers in the industry. The failure of batch pitch bearings has appeared, which has become a pain point for the entire domestic and foreign industries, and the industry needs to reflect.

Wind power investment is a high-risk investment, and the calculation of return and rate of return is based on reliability. If a slewing bearing problem occurs during the entire life cycle, such as downtime, replacement, and even safety incidents, it is the result that developers and host manufacturers do not want to see. XZWD Slewing bearing has been committed to high-quality and high-stability slewing bearing, and has received unanimous praise in this industry line. To provide stable and reliable pitch bearings for wind turbines is the unremitting pursuit of every practitioner of XZWD . It is our unshirkable responsibility to minimize the risk of failure and control economic losses and safety risks.
