Backing Bearings

Backing bearings have been specially used for cold rolling mills. Most of them are used to process high grade steel strip and non-ferrous metal strip, but can also be used for other applications, e.g. straightening or bending machines. Backing bearings are roller bearings having a particularly thick-walled outer ring and can be mounted on stationary support shafts to form back-up or straightening rolls. The forces from the work rolls are transmitted via the support shaft and a system of support saddles to the roll or machine stands.
