Heavy Rolling and Plain Bearings in the London Eye
Two specially-designed INA large spherical plain bearings hold the London Eye in a safe upright position. With outside diameters of 600 mm and a weight of 194 kg each, they were indispensable for moving the wheel from its horizontal mounting position across the Thames into a vertical position. Since then, the bearings have had to compensate micro movements caused by the wind. Thanks to ELGOGLIDE®, the bearings can support extremely high loads and are maintenance-free. The load carrying capacity of the ELGOGLIDE® coating was proved in comprehensive tests on INA’s in-house test stands.
According to specifications, the spherical roller bearings used in the hub were to have a life of more than 50 years. Therefore, application engineers decided to use spherical roller bearings with through-bored rollers and pin cages. These cages incorporate the largest possible number of rolling elements per row compared with standard cages and guarantee a high radial load carrying capacity.
The fantastic view from the largest Ferris wheel in the world can be enjoyed safely, also thanks to INA and FAG.
