# Micron Precision Makes Bearings Sensitive to Deformations

## Micron Precision Makes Bearings Sensitive to Deformations

In machine tool building, processing precision at the micron and sub-micron level is required. This makes bearings extremely sensitive to any deformations: thermal, mechanical, and from installation stresses.

## Sources of Deformations

- Thermal expansion from internal and external heating
- Elastic deformations from loads
- Stresses from improper installation
- Wear of contact surfaces

## Solutions

Precision bearings of accuracy classes P4, P2 or ABEC 7, ABEC 9 are used. Bearings with thermal deformation compensation (floating bearings) are applied. Careful spindle balancing and temperature control are recommended.
