Classification of turntable bearings

Slewable bearings are divided into two series: crossed roller slewing bearings and four-point contact ball slewing bearings according to the rolling element structure. According to the gear form, they can be divided into without ring gear, with inner teeth, and with outer teeth. There are three types of teeth, which can install seals, pressure oil cups, and adjust the torque in a small range. The accuracy can reach P5/P4/P2 levels to adapt to various types of working conditions.

Customized design and processing of various types of high-precision non-standard bearings with dimensions ranging from outer diameter 20mm to outer diameter 2000mm. We have been working with many universities, scientific research institutes, and high-end machine tool manufacturing companies for many years. , Machinery Research Institute and other institutions to jointly develop major equipment and assist customers in sample and mass production.

The classification of slew plate bearings is as follows:

1. External ring gear slew plate bearing (XSA series)

2. Internal ring gear slew plate bearing (XSI Series)

3. Crossed roller slew bearings (XSU series)

4. External ring gear four-point contact ball slew bearings (VSA series)

5 , Internal ring gear four-point contact ball slew bearing (VSI series)

6. Four-point contact ball slew bearing (VSU series)

7. Crossed roller slew bearing (XSU08 series) )

Slewing bearings can bear comprehensive loads such as large radial load, axial load and overturning moment at the same time. They integrate multiple functions such as support, rotation, transmission and fixation, and are compact in structure and easy to install. , easy to maintain, usually used in heavy-load and low-speed applications such as cranes, excavators, rotary tables, wind turbines, astronomical telescopes, tank turrets and other devices, and are widely used.
