Large rolling bearings are widely used in industrial applications
Large-sized rolling bearings are often used in heavy machinery and industrial equipment, where they can withstand larger loads and provide good support. The following are some common large-size rolling bearings and their main applications and characteristics:
Tapered Roller Bearings:
Application: Commonly used in heavy trucks, construction machinery, railway vehicles, and agricultural machinery, etc.
Features: Can withstand radial and axial loads, can handle larger loads and instantaneous loads, has high load-bearing capacity, and good rigidity.
SKF 302xx, 303xx, and other series, such as 30210, 30220, 30308, 30320, etc.

Spherical Roller Bearings:
Application: Suitable for heavy machinery, such as excavators, metallurgical equipment, cement plants, etc.
Features: It has an automatic alignment function, can adapt to the relative offset of the shaft and the housing,
provides good axial and radial support, and is suitable for high-speed rotation.
