Sendzimir Mill Bearing

Backing up roller bearing also called Senzimir mill bearings,it was specially designed for cold rolling mills, Most 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.
1)Structure & Feature: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.

2)Processing accuracy:running accuracy must be P4 at least,dimensional accuracy no less than P5;
were classified in three to seven section height groups each of 3μm to 5μm;
were suitable for high strip speeds, up to 1000 m/min depending on operating conditions.
We are manufacturing this bearing in 3 structures.
