Spherical roller bearings
iii) Tapered roller bearings:
Tapered roller bearings are the undisputed champions of load support, effortlessly handling radial and axial forces. They ensure smooth rotation, especially in tight corners. The rollers are placed between two raceways that are sections of a hollow cone. This cone serves as a load-bearing element. Tapered roller bearings can be applied back-to-back to allow for equal axial load in both directions. They are used in gearboxes and automotive wheel hubs.

Needle bearings
They have cylindrical rollers that resemble needles exchange data because of their small radial size. This allows more rollers to be accommodated in the same space, increasing the contact area with the raceways. Their thin cylindrical rollers make them ideal for high radial loads. There are two types of needle roller bearings: needle roller bearings with an inner ring and needle roller bearings without an inner ring.
Their small size allows them to be used in applications where space is limited due to the reduced clearance between the housing and the axle. They find their place in motorcycles, compressors, pumps and the textile industry.

Thrust bearings
i) Ball bearing
These are special types of ball bearings designed for axial loads. They cannot accommodate radial loads. Thrust ball bearings provide smooth operation and minimal noise and are suitable for high-speed applications. The choice between unidirectional and bidirectional bearings depends on the unidirectional or bidirectional load. Applicable in automotive transmissions, turning machines and turbines.
Ball bearing
They consist of tapered or cylindrical rollers arranged perpendicular to the shaft axis. They thus offer high axial rigidity with minimal friction and high axial loads, making them ideal for heavy-duty applications. Thrust rollers can accommodate light shocks and unidirectional axial stresses. For low-speed applications, they are frequently used in contexts where thrust ball bearings are not practical. Examples of applications include crane hooks, winches, rolling mills and automotive steering systems.
