double row ball slewing bearing

The slewing bearing of loading and unloading machinery, especially the double-row ball slewing bearing, is a high-precision and high-load-bearing mechanical component. This product has a unique structural design and excellent performance characteristics, and plays an indispensable role in various types of loading and unloading machinery.

In amusement equipment, slewing bearings are used in Ferris wheels, large pendulums, and flying chairs. Broadly speaking, a slewing bearing is a large bearing that can withstand comprehensive loads, and can bear large axial, radial loads and overturning moments at the same time. Slewing bearings generally have mounting holes, internal gears or external gears, lubricating oil holes and sealing devices, so that the design of the main engine can be compact, easy to guide, and easy to maintain. Ferris wheel usually adopts double row ball slewing bearing. There are two rows of rolling elements, which can bear large axial load, radial load and tilting moment. It rotates flexibly and stably with higher safety factor. For some large ferris wheel, four contact ball slewing bearing is selected too, outer dia is about 4100mm, depth 85mm. Slewing ring bearings used on Ferris/Sky wheels are used with inner rings. In most cases, the bearing should be light enough and safe enough to rotate. The slewing ring bearings used on the Ferris wheel/sky wheel generally require a long service time, so it is also very important for anti-corrosion.
