Cylindrical roller bearings carry heavy radial load through line contact, in a separable design that simplifies mounting and dismounting. Certain designs guide the rollers axially or permit axial displacement of the shaft.
The standard choice for electric motor rotors, gearboxes, machine tool spindles and rolling mills under heavy radial load at moderate speed.
Process Overview
Cylindrical roller bearings carry radial load through line contact between rollers and raceways, supporting much higher radial capacity than a same-size ball bearing. The separable design (inner ring, outer ring and roller cage assemble independently) simplifies mounting and dismounting.
Depending on the ring flange design, the rollers guide axially and the bearing may permit axial displacement of the shaft — making them the standard choice for electric motor rotors, gearboxes, machine tool spindles and rolling mills under heavy radial load at moderate speed.
