Production Description:

Backing bearings have been specially developed for cold rolling mills of the cluster type, But can also be used for other applications, Eg, Straightening or bending machines. Backing bearings are roller bearings having a particularly thick- Walled outer ring and can be mounted on stationary support shaft and a system of support saddles to the roll of machine stands.

Backing bearings for cluster mills are produced in many design but are generally based on double or three- Row cylindrical roller bearings. Single row needle roller bearing and double row taper roller bearing design are also available. The logarithmic contact profile between rollers and raceways produces a vastly improved stress distribution under all load conditions as well as when the bearing is misaligned under load. An optimised finish on all surfaces in contact serves to enhance lubrication condition. As lubricant is supplied to the bearings via the support shaft , ZWHZZ backing bearings have lubrication holes and some have one or more annular grooves in the inner ring.
