Slewing bearings are also called turntable bearings. Unlike ordinary bearings, slewing bearings usually have mounting holes, internal or external gears, lubricating oil holes and seals. Therefore, this product has the characteristics of compact structure, convenient guidance and convenient maintenance. Slewing bearings are composed of outer rings, inner rings, rolling elements, etc. They are mechanical parts that can withstand large axial, radial and tipping moments and have good load-bearing capacity.

Advantages of slewing bearings

1. The size of slewing bearings is generally large, with a diameter of 0.4~10 m, and some even reach 40 m. The bearings can be customized according to the characteristics of the mechanical equipment.

2. Slewing bearings usually bear multiple loads, including axial force, radial force, and huge overturning moment. Therefore, slewing bearings can play the role of several sets of ordinary rolling bearings.

3. The speed of the slewing bearing is relatively low, usually not exceeding 10 rpm. In addition, in most cases, the slewing bearing does not rotate continuously, but only rotates back and forth at a specific angle, just like a "swing bearing".

4. There are great differences between slewing bearings and rolling bearings in manufacturing process, materials and heat treatment. The slewing bearing has a gear ring for rotary drive and a seal for dust prevention.

5. The size of the slewing bearing is very large. Unlike ordinary bearings, it is not mounted on the central shaft and installed in the bearing box, but is fastened to the upper and lower supports with screws.
