According to customer requirements
Sliding bearings are sliding friction, with large contact surface, simple structure, small volume, strong bearing capacity, good vibration resistance, but large friction coefficient, easy to generate heat, need sufficient lubrication, suitable for low speed and heavy load
Rolling bearings are rolling friction, compared with sliding bearings, their contact surface is small (point contact for ball bearings, line contact for roller bearings), small friction coefficient, less heat generation; less wear and tear, good accuracy retention; suitable for higher speeds run down. However, the bearing capacity is slightly poorer and the vibration resistance is poorer.

Single row tapered roller bearings are normally used in applications with combined loads. Single row tapered roller bearings can also be used in sets. Single row tapered roller bearings can be matched face-to-face, back-to-back or in tandem to provide specific advantages depending on operating conditions.
Double-row tapered roller bearings are commonly used in gearboxes, lifting equipment, rolling mills and machines in the mining industry.
Four-row tapered roller bearings are used almost exclusively in work roll applications such as rolling mills.
