Wind turbine slewing bearing
Shandong Yongqiang Forging is a high-end manufacturing enterprise integrating forging blanks and slewing bearing processing. We are committed to providing various standard and non-standard slewing bearing solutions for the machinery industry. Slewing bearings are widely used in the machinery industry and provide stable operating accuracy. They also do an excellent job in reducing weight, creating space, reducing friction, and extending service life. Yongqiang offers a variety of raw material materials, internal assembly options, lubricants and corrosion-resistant options. We provide slewing bearings with raceway center distances from 100mm to 2500mm. The sealing effect of our slewing bearing during operation effectively guarantees the internal lubrication of the slewing bearing and extends its service life. As a main engine supporting manufacturer of construction machinery, we can provide stable and reliable slewing bearing operation solutions.
