Three-row roller pitch bearing
Category:
High-end core components specially designed for high-power wind turbines feature a unique three-row roller arrangement that ensures precise load distribution—axial, radial, and overturning moment loads are each borne by independent raceways, endowing the product with exceptionally high rigidity and outstanding load-carrying capacity. These components can effortlessly handle the demanding dynamic loads generated by massive blades, guaranteeing precise control, stable operation, and reliable performance of the pitch system even under harsh operating conditions. They serve as a critical support for ensuring the safe and efficient operation of high-power wind turbines.
Innovative Technologies: A multi-lip sealing structure design significantly enhances sealing reliability; optimized logarithmic roller geometry strengthens load-carrying performance; precision grinding and shaping of the raceway ensures its straightness; a specialized measuring instrument for axial raceways guarantees high accuracy in axial clearance measurement; and an internal anti-rust oil coating technology improves corrosion resistance, boosts installation efficiency, and reduces the cost of corrosion protection for mounting holes.
Core technical specifications: Bearing end runout 0.3 mm, tooth runout 0.65 mm; under operating conditions at 0.5 rpm, torque ripple ≤ 10%; designed service life up to 20 years.
