Backing bearingBacking bearings have been specially developed for cold rolling mills of the cluster type, but can also be used for other applications, such as straightening or bending machines. These bearings have a particularly thick-walled outer ring and can be mounted on stationary support shafts to form backup or straightening rolls.
- Super-precision quality for tolerances of run-out
- Very tight tolerances for the cross-sectional height
- Designed for high loads
