ball slewing bearing

  • high quality customizable construction machinery slewing bearings

    The single-row four-point contact ball slewing bearing is composed of two seat rings. It has a compact structure and light weight. The steel balls are in four-point contact with the arc raceway and can withstand axial force, radial force and overturning moment at the same time. Construction machinery such as rotary conveyors, welding operators, small and medium-sized cranes and excavators can all be used.

  • Slewing Bearing For Ferris Wheel

    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. If non-standard customization is required, our company can provide technical support such as selection, design, calculation, etc.

  • Single Row Four Point Contact Ball Slewing Ring( Q Series)

    Single row four point contact ball slewing ring Q series is a standard model series in China. Q means single row ball type. QW is external gear type, QN is internal gear type, QU is non gear type. It is made of two seat rings. The balls and the raceway are with four points contact, via which the axial force, radial force and resultant moment is born simultaneously. Outer Diameter is from 360 mm to 4700mm. Standard material we adopt is 50Mn and 42CrMo. Other customized material is also acceptable. We support models selection based on your application; teeth quenching and grinding; customized surface treatment like Blackening, phosphating, galvanizing, sandblasting and etc. In the production process of slewing ring bearing, whole process inspection is implemented strictly to ensure that each set of products are qualified. For high-precision products, precise grinding is used to effectively control the parameters of ring ellipse, wall thickness and flatness, so as to ensure that the precision of finished products meets the requirements of standards or customer drawings. This series models are with advantage of compact design, flexible rotating and light weight. It is widely used on rotary conveyor, welding arm and positioner, light/medium duty cranes, excavators and other engineering machines. Please feel free to tell us the application you use and we can help you choose the proper model and offer you a professional solution as soon as possible.
