# Back-up Roll Bearings

## Back-up Roll Bearings

Back-up rolls support the work rolls and bear significant loads. The support bearings operate under extreme loads and must ensure precise roll positioning.

## Functions

- Support for work rolls
- Radial load bearing
- Precise positioning
- Axial displacement compensation

## Solutions

Multi-row cylindrical roller bearings and tapered roller bearings are used. Bearings with increased clearance are applied. The use of bearings with circulating lubrication is recommended.
