What are the advantages of crossed roller bearings?

 

 

Abstract:

Crossed roller bearings are a type of bearing widely used in industrial fields. Its characteristic is that it can bear radial, axial and angular loads at the same time, so it has been widely used in heavy-load, high-speed, high-precision and multi-motion direction mechanical equipment. Below we will introduce the advantages of crossed roller bearings in detail.

Crossed roller bearings are a type of bearing widely used in industrial fields. Its characteristic is that it can bear radial, axial and angular loads at the same time, so it has been widely used in heavy-load, high-speed, high-precision and multi-motion direction mechanical equipment. Below we will introduce the advantages of crossed roller bearings in detail.

1. Strong load-bearing capacity

Cross roller bearings can bear radial, axial and angular loads at the same time, so their load-bearing capacity is very strong. Since there are two mutually perpendicular raceways inside the bearing, the bearing’s load-bearing capacity is equivalent to that of a deep groove ball bearing when bearing radial loads. When bearing axial loads, the bearing’s load-bearing capacity is greater than that of a thrust ball bearing, and when bearing angular loads, the bearing’s load-bearing capacity is greater than that of a four-point contact ball bearing. Therefore, in mechanical equipment that needs to bear loads in multiple directions at the same time, cross roller bearings are a very ideal bearing.

2. Small size, large load capacity

The structure of the cross roller bearing is very compact and relatively small in size. However, its load capacity is very large. Compared with other types of bearings, the load capacity of the cross roller bearing is about three times that of them. Therefore, in mechanical equipment that needs to carry a large load in a small size, the cross roller bearing is a very suitable choice.

3. Simple structure and easy installation

The structure of the crossed roller bearing is relatively simple. Since there is no contact between the rollers, the friction inside the bearing is relatively small and the service life is relatively long. In addition, the installation method of the crossed roller bearing is also very simple. You only need to install the bearing into the bearing seat and then fix the bearing seat on the shaft with screws. Compared with other types of bearings, the installation of the crossed roller bearing does not require any adjustment, so it can save a lot of installation time and cost.

4. High precision can be achieved

The internal structure of the cross roller bearing is of high precision, so it can achieve high rotation accuracy. In some high-precision mechanical equipment, cross roller bearings are often used to support rotating shafts.

In short, the advantages of crossed roller bearings include strong carrying capacity, small size, large load capacity, stable operation, long service life, simple structure, easy installation and high precision. These advantages make crossed roller bearings widely used in the industrial field, especially in heavy-load, high-speed, high-precision and multi-movement direction mechanical equipment, where they are indispensable key components.
