# Precise Positioning of Robot Joints for Reliable Movement

## Precise Positioning of Robot Joints for Reliable Movement

Industrial robot joints must ensure precise positioning with an error of fractions of a degree. Bearings play a key role in achieving high repeatability accuracy.

## Accuracy Requirements

- Positioning error less than 0.01°
- Positioning repeatability
- Minimum bearing clearances
- High rigidity under loads

## Solutions

Precision ball and roller bearings of accuracy classes P2 and P4 are used. Bearings with preload are applied to eliminate clearances. The use of paired bearing sets is recommended.
