# Multi-directional Movements Require Bearings for Complex Loads

## Multi-directional Movements Require Bearings for Complex Loads

Robot joints perform movements in multiple directions simultaneously. Bearings must withstand complex combined loads: radial, axial, and moment loads.

## Load Types

- Radial loads from manipulator weight
- Axial loads from axial thrust
- Moment loads from eccentric loads
- Dynamic loads during acceleration and deceleration

## Solutions

Combination bearings are used: angular contact ball bearings and four-point bearings. Bearings with an increased number of balls are employed to withstand loads in all directions. The use of paired sets is recommended.
