Four-row Tapered Roller Bearings
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.
Multi-row Tapered 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.
