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.
General features
Outer rings: in special bearing steel. Isothermal hardening is
foreseen in case of big dimensions in order to improve bearings
toughness and strength.
On request: isothermal hardening or case hardening also on smaller
sizes.
The outer ring is conveniently profiled to reduce the stress
generated by the contact with the work rolls.
Inner rings: in special bearing steel, available with lubrication
holes.
Rollers: with modified logarithmic profiles to improve the
distribution of stresses.
Each bearing is measured and identified according to a specific
selection of the outer ring’s thickness H.
This refers to the alignment of the outer ring and inner ring.
The maximum thickness of outer and inner rings is marked on the
rings sides.
On request, the bearings can be packed in a sequence of assembly
and in groups according to the customer’s requirement.
