How to Adjust the Clearance of Slewing Bearing? How to Reduce the Noise of the Slewing Ring Gear
Read More >
There are many models of cross roller slewing bearing, and they are widely used. This has led some manufacturers to have difficulty in selecting the correct type. However, the selection of models is not complicated. You just need to choose according to your own needs. So, what are the selection methods for cross roller slewing bearing? Let's take a look.
There are various types of cross roller slewing bearing. According to the structure of the rolling elements, they can be divided into cylindrical roller bearings and tapered roller bearings. These two types of bearings have different characteristics and are not completely applicable to the same fields. Crossed tapered roller bearings are suitable for fields such as machine tools, industrial robots, and measuring instruments, while crossed cylindrical roller bearings are suitable for the joints of industrial robots and the rotating worktables of machining centers.
Before selecting the model of the crossed roller bearing, you need to determine the size first, and then select the appropriate crossed roller bearing according to the size of the shaft. Before selection, you need to determine the reserved space and judge the size of the bearing that you can use, as well as reduce the installation space as much as possible, making the installation of the bearing more flexible.
Cross roller slewing bearing have different structures, such as outer ring split type, inner ring split type, and integral structure. Before selecting a crossed roller bearing, you need to judge which structure of bearing you need to choose, and determine whether the part driven by the bearing is the inner ring or the outer ring. If the outer ring rotates, choose the inner ring split type; if the inner ring rotates, choose the outer ring split type.
From the installation method, cross roller slewing bearing are divided into two types: inner and outer rings with installation holes and inner and outer rings without installation holes. The type with installation holes is easier to install and can be directly connected by fixing bolts, while the type without installation holes needs to be installed through the bearing seat, pressing flange, and interference fit between the shaft and the bearing inner diameter. Choose an appropriate crossed roller bearing according to the installation method you need to use.
The carrying capacity of cross roller slewing bearing is a critical factor in selecting the bearing type. Before choosing which type of crossed roller bearing to use, you need to know approximately how much load the equipment will impose and select according to the required carrying capacity of the equipment.
These are all the selection methods related to cross roller slewing bearing. Hopefully, they will be helpful to you. The selection of the model of cross roller slewing bearing should be determined according to usage requirements. Choosing the appropriate model can avoid some problems in the use process and improve the efficiency of use.
