Our backingup bearing are mainly used to roll Silicon plate or sthin-section steel plate. These bearings have a particularly thick-walled outer ring and can be mounted on stationary support shafts to form backup or straightening rolls. Our backing bearings are used on the eight support shafts of a 20-roll mill.<\/p>\n\n\n\n
