Slewing bearing for Ferris Wheel
    When it comes to giant observation wheels and classic Ferris rides, the heart of smooth, safe rotation lies in one critical component: the slewing bearing. As a specialized Chinese manufacturer with over 20 years of experience in large-diameter rotational solutions, we engineer turntable bearings that meet the unique demands of amusement structures—where human safety, weather exposure, and continuous cyclic loading converge.

Our Ferris wheel bearing series includes three primary configurations tailored to wheel diameter, passenger capacity, and drive system architecture:
  • Single-Row Four-Point Contact Ball Bearings – Ideal for mid-sized wheels (30–60m diameter), offering compact design with balanced axial/radial load handling.
  • Double-Row Ball Slewing Rings – Engineered for larger observation wheels (60–100m+), providing enhanced moment load resistance and smoother rotation under eccentric loads.


  • Triple-Row Roller Slewing Bearings – The ultimate choice for super-giant wheels (>100m) or high-wind coastal installations, delivering maximum rigidity and fatigue life under extreme overturning moments.

Each unit is manufactured in our ISO 9001-certified facility using vacuum-degassed 42CrMo4 or 50Mn alloy steel, induction-hardened raceways (HRC 55–62), and multi-lip sealing systems rated IP66 or higher. We don’t just sell bearings—we deliver rotation confidence.
