The two custom-designed SKF spherical roller bearings (one within each side) will be virtually unprecedented in weight and size. Each bearing will weigh approximately 8,800 kg and be designed with 2,300mm outer diameter, 1,600mm inner diameter, and width of 630mm. Specially engineered features will include W26 lubrication holes in the inner ring, SKF NoWear-coated rollers, and PTFE coating in the bore. SKF additionally will incorporate advanced lubrication, sealing, and online condition-monitoring systems and take the lead in monitoring the bearings once the wheel is up and running.
SKF was awarded the contract by American Bridge Company (Coraopolis, PA, USA), which is responsible for constructing the 143m-diameter tension wheel. In addition to the two SKF bearing assemblies, the structure will consist of four steel support legs, a single braced leg, fixed spindle, rotating hub, 2m-diameter tubular rim, and 112 locked coil cable assemblies as spokes.
The Las Vegas High Roller is the centerpiece of The LINQ, a planned $550 million, open-air retail, dining, and entertainment district situated between Imperial Palace and Flamingo Las Vegas. Each of the wheel’s 28 supersize cabins (which themselves will revolve) will accommodate up to 40 people during a 30-minute ride.
The Las Vegas High Roller turns out to be the latest SKF big-wheel project in a growing portfolio of expertise. The Navy Pier Ferris wheel in Chicago similarly operates with two SKF spherical roller bearings and SKF Reliability Systems retains responsibility for ongoing proactive maintenance programs.
