The difference between tapered roller bearings and cylindrical roller bearings

Release time:

2025-01-10

Conical roller bearings: They can withstand both radial and axial loads, especially when subjected to larger radial loads, and their performance is superior to other thrust bearings. It can transmit unidirectional axial loads. If it is necessary to transmit axial loads in the opposite direction, another tapered roller bearing symmetrically installed with it is required.

There are significant differences between tapered roller bearings and cylindrical roller bearings in terms of structure, bearing range, and application scenarios.

Structural differences

Cylindrical roller bearings: The rolling elements are cylindrical rollers, usually arranged in parallel. Spacers are installed between the rollers to prevent tilting or friction between them. Belonging to a

separable bearing, the inner or outer ring can be separated for easy installation and disassembly. ‌

Conical roller bearing: The rolling element is a conical roller composed of inner and outer rings and rollers, and the rollers form a certain conical angle with the track surface. The component

usually composed of an inner ring, rollers, and a cage, and the outer ring can be installed separately for a separate design.

Difference in tolerance range

Cylindrical roller bearings: mainly bear radial loads, but can also withstand a certain degree of axial loads. Some types of cylindrical roller bearings, such as NN and NNU double row cylindrical

roller bearings, have higher load-bearing capacity and are suitable for heavy-duty applications such as machine tool spindles.

Conical roller bearings: They can withstand both radial and axial loads, especially when subjected to larger radial loads, and their performance is superior to other thrust bearings. It can transmit

unidirectional axial loads. If it is necessary to transmit axial loads in the opposite direction, another tapered roller bearing symmetrically installed with it is required.

Differences in application scenarios

Cylindrical roller bearings: widely used in motors, machine tools, petroleum, rolling mill loading and unloading machinery, and various industrial machinery. Excellent performance in situations

requiring high speed, high load, and high precision.

Conical roller bearings: mainly used in the fields of automobiles, aerospace, mining machinery, etc. It plays a crucial role in the transmission system of automobiles, such as gearboxes,

differentials, half shafts, etc. In aerospace equipment, tapered roller bearings can withstand enormous axial and radial loads, and require extremely high rotational speed and accuracy. In mining

machinery equipment, tapered roller bearings have become indispensable components due to their ability to withstand large axial and radial loads, as well as their high rotational speed and

accuracy.
