Roller bearings contain cylindrical rolling elements instead of balls as load-carrying elements between the races. An element is considered a roller if its length is longer than its diameter (even if only slightly). Since they are in line contact with the inner and outer races (instead of point contact as in the case of ball bearings), they can support greater loading.

Roller bearings are also available in various types. The appropriate type may be selected after considering the type and magnitude of loading, service conditions, and the possibility of misalignment among other factors.

 

Advantages of Roller bearings:

Low friction
Easy maintenance
Can take high radial loads
Tapered roller bearings can withstand high axial loads
Great accuracy
Used to adjust the axial displacement
 

Tapered Roller Bearings

The tapered roller bearing contains sections of a cone as a load-carrying element. These rollers fit between the two races that are also sections of a hollow cone. If the races and the axes of rollers were extended, they would all meet at a common point.

Tapered roller bearings are designed to handle higher axial loads besides radial loads. The larger the half-angle of this common cone, the more axial load it can sustain. Thus they work as thrust bearings as well as radial load bearings.

Applications:

Agriculture, construction and mining equipment, sports robot combat, axle systems, gearbox, engine motors and reducers, propeller shaft, railroad axle-box, differential, wind turbines, etc.

Spherical Roller Bearings

Heavy radial and axial loads can be a greater challenge when the shaft is prone to misalignment.

This situation can be handled very well by spherical roller bearings. They have high load-carrying capacities and can manage misalignment between the shaft and housing. This reduces maintenance costs and improves service life.

Spherical roller bearing raceways are inclined at an angle to the bearing axis. Instead of straight sides, the rollers have spherical sides that fit onto the spherical raceways and accommodate small misalignments.

Spherical roller bearings have a wide range of use cases. They are used in applications where heavy loads, moderate to high speeds and possible misalignment occur. Some examples are off-road vehicles, pumps, mechanical fans, marine propulsion, wind turbines, and gearboxes.

Applications:

Gearboxes, wind turbines, continuous casting machines, material handling, pumps, mechanical fans and blowers, mining and construction equipment, pulp and paper processing equipment, marine propulsion and offshore drilling, off-road vehicles.
