Four-rows tapered roller bearing is successfully used in rolling mill bearing configurations around the world where the rolling speed is from low to medium speed. Four-rows tapered roller bearings are used in heavy machines such as large cold and hot rolling mills in plastic machinery industries
Tapered roller bearing inner diameter and roller neck adopt loose fit, which is very convenient to install and disassemble, but sometimes sliding creep will be caused by loose fit, so the inner diameter is often processed with spiral oil groove.
With high reliability and long life, can prevent the occurrence of sudden accidents. Good sealing, not only make the working environment cleaner; Moreover, the consumption of grease is reduced. Maintenance cost reduction.
With high reliability and long life, can prevent the occurrence of sudden accidents. Maintenance cost reduction. The rolling of the bearing for the support roller improves the rolling precision of the steel plate.
