Four-row Tapered roller bearings are used
for the roll necks of rolling machines and for other applications
where heavy or impact loads are present.
roller bearings have the serial number and the combination
symbol stamped on the faces of the rings for clearance
adjustment and must be assembled according to this number
and symbol. Pressed steel cages are used for small bore
bearings and machined, high-strength brass or mild-steel
cages are used for bearings with larger bores. Heavy-duty
pin-type cages are used for some large-bore bearings.
