The main difference between the two designs lies in the contact between the rolling elements and the raceway surface. Imagine a deep groove ball bearing and a cylindrical roller bearing: In a the deep groove ball bearing, the contact between the balls and the raceway is point-shaped from a geometrical point of view. Whereas in the rolling elements of a cylindrical roller bearing contact the raceway in a linear manner.

Point and line contact describes the type of contact between rolling elements and a raceway surface Point contact in ball bearings: Contact of the rolling elements with the raceway at one point Line contact in roller bearings: Contact of therolling elements with the raceway in a line

Both types of contact have advantages and disadvantages. Point contact offers the advantage that ball bearings can be operated at a high speed. They are sometimes used in machine tools or electric motors. However, ball bearings cannot support as much load as roller bearings. The rolling elements of roller bearings offer a larger contact area to the raceways than balls. As a result, bearings with line contact can generally support higher loads than ball bearings and have greater stiffness. On the other hand, the frictional torque is higher than with ball bearings. Due to the linear contact, roller bearings are therefore used in applications with comparatively low speeds – for example in gearboxes.

The angular contact ball bearing is virtually the brother of the deep groove ball bearing. Characteristics of angular contact ball bearings Perhaps you already know

You may have already heard that rolling bearings can be split into two types. The classification depends on the shape of the rolling elements (balls or rollers/needles), so that a basic distinction is made between ball and roller bearings.

Components of rolling bearings The basics of rolling bearing technology include the structure and function of rolling bearings. To get you started slowly, you will

Characteristics of tapered roller bearings Here you see an NTN tapered roller bearing. As the name suggests, tapered roller bearings are roller bearings, whereby the

Characteristics of cylindrical roller bearings Do you remember the characteristic that all roller bearings have in common? We are talking about line contact, which can
