Double-row ball pitch bearing
Category:
As a core solution for pitch systems that boasts mature technology and wide-ranging applications, the double-row spherical pitch bearing adopts a two-point contact ball rolling structure. Compared to the three-row roller structure, it offers significant advantages such as lower friction torque and more flexible rotation. By optimizing the raceway design and precisely matching steel balls, this bearing not only ensures sufficient load-carrying capacity but also achieves outstanding dynamic response performance, perfectly meeting the critical requirements of medium- and large-scale wind turbine units for sensitivity and operational efficiency of their pitch systems.
Innovative Technologies: A uniquely designed roller path profile shaping rolling ring technology; integrated sealing structure for enhanced protection; high-precision roller path machining using turning instead of grinding; and automatic in-hole painting technology for corrosion prevention.
Core technical specifications: Bearing end runout 0.3 mm, tooth runout 0.8 mm; under operating conditions of 0.3–0.5 rpm, torque ripple ≤ 15%; designed service life up to 20 years.
