Large Turntable Cross Roller Slewing Bearing for Auto

Large Turntable Cross Roller Slewing Bearing for Auto

Luoyang Xinqianglian Slewing Bearing Co., Ltd.  ( Hereinafter referred to as the LYXQL) founded in 2003, is located in the ancient capital of nine dynasties Luoyang in Henan province. LYXQL is a national key high-tech enterprises and become a GEM listing company successfully on July 13,2020 (stock code "300850").

LYXQL Turntable Large Cross Roller Slewing Bearing is an important part of Auto .Its work safety, reliability requirements are very high. The Large Cross Roller Slewing Bearing for Auto is characterized by low speed and high load.LYXQL Large Cross Roller Slewing Bearing can support combinations of large radial force, medium axial force and tilting moment with small or zero clearance. Main applications of this kind of bearings are hoisting and mechanical handling and general mechanical engineering etc.The product outer dimension can be from 500mm to 25000mm.

LYXQL Turntable Cross Roller Slewing Bearing for Auto Features:

1.Crossed roller bearings can be assembled in all directions of the main shaft and are easy to use.

2. It can bear radial and axial loads at the same time, so the structure of the equipment can be simplified and the weight of the mechanism can be reduced.

3. Crossed roller bearings consume less lubricating grease due to high rotation efficiency and low heat dissipation.

4. It can reach negative clearance and has extremely high rotation accuracy.

5. High rigidity, 3-4 times stronger than the rigidity of traditional bearings.

6. High load-carrying capacity, the rollers are in line contact with the raceway, which can withstand higher loads.

LYXQL Turntable Large Cross Roller Slewing Bearing---- Seal

The sealing of the cross roller slewing bearing without teeth is mainly to prevent the filled grease from leaking out, and also to prevent external dust, impurities and moisture from entering the inside of the bearing and affecting the normal operation of the bearing.

Since most of the slewing bearings work under heavy loads and low speeds, the sealing form of the bearings adopts two structures: rubber seal ring seal and labyrinth seal. The rubber sealing ring itself has a simple structure, small space occupation and reliable sealing performance. The disadvantage is that it is prone to early aging under high temperature conditions and loss of airtightness. Therefore, under high temperature conditions, the slewing bearing should adopt a labyrinth seal. In addition, the material of the sealing ring under high temperature is high temperature resistant fluoro rubber.
