Introduction

Cognition slewing bearing

  • Slewing bearing structure

A lot of types of slewing bearings, but the structure composed looks same, figure 1 is the basic structure for slewing bearing

  • Main installation ways of slewing bearing

There are the following main installation ways: Seat type installation, suspension type installation and vertical installation. Both the inner ring and outer ring of the slewing bearing for vertical installation must be fitted with a positioning gag to guarantee accurate positioning of the bearing.

  • Material of the pivoting support

The materials of rolling ring of the slewing bearing produced by our company are generally high alloy-structural steels such as 50Mn, 42CrMo, stainless steel and other materials for special purposes. Rolling ring blanks, which are manufactured via rolling press or forging and have been processed by  normalizing or hardening and tempering, can fully guarantee the mechanical performance of the  material. Users can choose appropriate materials as required.

  • Temperatureand working environmentsuitable for the slewing bearing

The slewing bearing produced by our company can work normally at a temperature of -30℃~+70℃. If users need one which can be used in lower or higher temperature, the engineers and  technicians of our company can design it specially for you . If the slewing bearing works at an extremely-terrible environment such as under marine climate, dust or abrasive particles ( sand dust, cement, coal powder, etc. ),etc., special sealing rings, protective device and appropriate oil passage must be used. Therefor, to make your slewing bearing work normally , you must perform regular daily  maintenance well.

  • Rated life span of the slewing bearing

The life span of the slewing bearing depends on the environment for use, load, rotational speed, lubricating,precision of seat frame and maintenance work. In case of using normally, the rated life span of the slewing bearin g of our company is 6000 hours–10000 hours.
