Giant spherical roller bearings for Beijing Wheel

摘要

Two giant-sized spherical roller bearings from Schaeffler Group are complete and ready for use on the world's tallest observation wheel, China's brand new Beijing Wheel. In total, around 22 tonnes of steel has gone into producing the two hub bearings. Each bearing has an outside diameter of 3,200mm, an inner ring bore of 2,600mm and a ring width of 630mm. Each bearing incorporates 118 rollers, each of these weighing around 20kg. The hub bearings for the Beijing Wheel will operate 108 metres above the ground. The Beijing Wheel will be 208m high and is designed to accommodate 1,920 passengers. One revolution of the wheel will take 20 minutes to complete, but will enable guests to see stunning views of the city of Beijing.
