High Roller is a 550-foot tall (167.6 m), 520-foot (158.5 m) diameter giant Ferris wheel on the Las Vegas Strip in Paradise, Nevada, United States of America. It is owned and operated by Caesars Entertainment Corporation.
It opened to the public on March 31, 2014 and is currently the world's tallest Ferris wheel. It is 9 ft (2.7 m) taller than its predecessor, the 541-foot (165 m) Singapore Flyer, which had held the record since 2008.
High Roller was announced in August 2011 as the centerpiece of Caesars Entertainment Corporation's $550 million The LINQ. Arup Engineering, which previously consulted on the Singapore Flyer, acted as the structural engineer.
The wheel rotates on a pair of custom-designed spherical roller bearings, each weighing approximately 19,400 lb (8,800 kg). Each bearing has an outer diameter of 7.55 feet (2.30 m), an inner bore of 5.25 feet (1.60 m), and a width of 2.07 feet (0.63 m).
The outer rim comprises 28 sections, each 56 feet (17 m) long, which were temporarily held in place during construction by a pair of 275-foot (84 m) radial struts, prior to being permanently secured by four cables.
The passenger cabins (or capsules) are mounted on the wheel's outboard rim and are individually rotated by electric motors to smoothly maintain a horizontal cabin floor throughout each full rotation. Preliminary designs anticipated 32 passenger cabins, each with a 40-passenger capacity—with the final design accommodating 28 40-person cabins and a total capacity of 1,120 passengers.
Each 225-square-foot (20.9 m2)cabin weighs approximately 44,000 pounds (20,000 kg), has a diameter of 22 feet (6.7 m), includes 300 square feet (28 m2) of glass, and is equipped with eight flat-screen televisions and an iPod dock.
At night the wheel is illuminated by a 2,000-LED system which can display a single solid color, differently colored sections, multiple colors moving around the rim, and custom displays for special events and holidays.
In order to make the Ferris wheel more beautiful, ensure its stability in the limited space, the bottom adopts double A stand support and unilateral support.The rotation of Ferris wheel involves rotary motion, and its core power device is mainly high duty high quality slewing bearing and hydraulic drive.The large slewing bearing is installed at both ends of the Ferris wheel’s shaft. It can bear the huge axial force, the radial force and the tilting moment, guaranteeing the rotation of the tens of thousands of the Ferris wheel.
Xuzhou Wanda Slewing bearing co.,ltd is professional in produce slewing bearing. The single row four-point contact ball slewing bearing is commonly used in ordinary size Ferris wheel, of which the model 011.25.450F has been widely used.
