How to correctly install the tower crane slewing bearing

Tower crane slewing bearing is a kind of large special structure bearing that can bear large axial load, radial load and overturning moment and other comprehensive loads at the same time. In addition, the slewing bearing itself has the characteristics of compact structure, convenient guide rotation, easy installation and easy maintenance. How to correctly install the tower crane slewing bearing, the slewing bearing manufacturer reminds you to start from the following aspects:

First, carry out anti-rust treatment on the product

Considering the harsh working conditions of tower cranes, good anti-rust treatment can maintain the performance of the slewing bearing. Before the products leave the factory, the company has taken special paint or oxidation treatment measures on the outer surface of the products. The equipment has a long durability. According to the special requirements of customers, chrome plating (TDC) or nickel plating can also be used.

Second, the installation of tower crane slewing bearing

During installation, after the slewing bearing is hoisted in place, use a feeler gauge to check the flatness of the fitting plane, and the specific allowable flatness value shall be implemented in accordance with relevant regulations. If the clearance is too large, it should be re-machined. If the required flatness cannot be achieved by machining, plastic filling or partial gaskets can be used to ensure the accuracy of the installation plane and reduce vibration. In order to avoid the deformation of the slewing plate bearing after the bolt is tightened, which will affect the normal operation of the slewing plate bearing.
