Crossed roller bearings have a strong, inseparable inner and outer ring structure that easily achieves high stiffness and high precision, independent of the surrounding environment and its structure. It is especially suitable for equipment with medium to high speed. It has been used more and more widely in recent years. Due to the different performance of the equipment, the types of bearings used are also different. How to choose the appropriate bearing type and structure for the equipment? It is a question that most customers are confused about. How to select a crossed roller bearing can refer to the following requirements.

1. Determine the size range of crossed roller bearings

The external dimension of the crossed roller bearing is one of the important parameters. First of all, you need to know the size of the bearing you need to use. It can also be said that what is the installation size of the equipment that needs to install the bearing, and then you can determine the size of the bearing.

2. Select the structural form of the bearing

Because crossed roller bearings have the same external dimensions, there are also many kinds of structures, including outer ring split type (RB/RA), inner ring split type (RE), and integral structure (RU/CRBH). The key is to see The part that the bearing needs to drive the rotation needs to be installed on the inner ring or the outer ring of the bearing. If the outer ring needs to be rotated, the inner ring split type must be used; similarly, if the inner ring rotation accuracy is required, the outer ring split type must be used.
