The main rolling bearings used on rollers are double row spherical roller bearings, four row tapered roller bearings, and multi row cylindrical roller bearings. Needle roller bearings are only used for work rolls in individual cases. Due to the high rigidity and low friction coefficient of rolling bearings, but with large overall dimensions, they are mostly used in various strip mills and continuous steel rolling mills.

(1) High workload and limited radial dimensions. During steel rolling, the rolling torque is large and accompanied by impact load; Due to the requirement of the steel rolling process that the overall dimension of the roller bearing seat must be smaller than the minimum diameter of the roller body, the overall dimension of the roller bearing is limited and the unit load is large.

A gear shaft is a mechanical component that supports and rotates with rotating parts to transmit motion, torque, or bending moment. Generally, it is in the shape of a metal round rod, and each segment can have different diameters. The rotating parts of the machine are mounted on the shaft.

Roller bearings are important components that support the roller and maintain its correct position in the rack. The requirements for roller bearings are small friction coefficient, sufficient strength, small deformation, long service life, and easy roll replacement. The working characteristic of roller bearings is to withstand very high unit loads, which is due to the considerable rolling force to be borne within a shorter roll neck. Roller bearings can be divided into two types: one is sliding bearings, and the other is rolling bearings.
