Backing bearings ( Back-up bearings )

Update date: 2020-10-25 00:50　 Attention: | Inquiry entry: sales@fv-bearing.com 　

FV backing bearings are available in many designs and variants. The main assortment is based on double or three-row cylindrical roller bearings. Single row needle roller bearing and double row tapered roller bearing designs are also available.
Backing 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. We shows the arrangement of the backing bearings on the eight support shafts of a 20-roll mill.
