1. Selection of bearing types

Cross roller bearings can be divided into cylindrical roller bearings and tapered roller bearings according to the different structures of the rolling elements. Cross tapered roller bearings are suitable for machine tools, industrial robots, measuring instruments and other fields, and cross cylindrical roller bearings are suitable for the joints or rotating parts of industrial robots, rotary tables of machining centers, etc.

2. Bearing size

Before choosing a cross roller bearing model, you must first determine the size, and then choose a suitable cross roller bearing according to the size of the shaft. Before selecting the model, you must determine the reserved space and judge the size of the bearing you can use, so as to reduce the installation space as much as possible and make the installation selection of the bearing more free.

3. Bearing installation method

From the installation method, cross roller bearings are divided into two types: inner and outer rings with mounting holes and inner and outer rings without mounting holes. The inner and outer rings with mounting holes are more convenient to install and can be directly connected by bolts. The bearings without mounting holes must be installed through the bearing seat and the clamping flange. Choose a suitable cross roller bearing according to the installation method you need.

4. Bearing load capacity

The load capacity of the crossed roller bearing is a key factor in the selection of bearings. Before choosing which type of crossed roller bearing to use, it is necessary to understand the approximate load applied by the equipment and make the selection based on the load capacity required by the equipment.
