Ball bearings — versatile for radial and axial forces

Ball bearings are the most popular rolling bearings. Due to the structure with balls as rolling elements arise different applications. Radial ball bearings are particularly suitable for radial loads. Axial ball bearings, also called longitudinal bearings, are designed to withstand forces working in the direction of the shaft.

Geometric structure of the ball bearing

Special design of the ball bearing

Maximum permissible load capacity of the bearing based on the materials used and the geometric design.

Noise level of the bearing during operation.

Smooth-running bearings have low frictional resistance.

Resistance of the materials used in the bearing to water and other corrosive media.

Maximum permissible speed of the bearing.

Protection of the bearing from the ingress of foreign particles and liquids.

Highest ambient temperature at which the bearing can be used without restrictions

Lowest ambient temperature at which the bearing can be used without restrictions

Accuracy of main dimensions (inner diameter, outer diameter and width). P0 is the standard tolerance class, P6 and especially P5 are a bit more precise.

The bearing clearance is the amount by which the two rings of a non-installed roller bearing can be displaced in relation to one another. There are different internal clearance classes. CN is "normal internal clearance" and is the best choice for many applications. C3, C4, ... indicates increased clearance. C2, C1, ... stands for reduced clearance.

Type of sealing of the bearing to protect it from contamination.

Inner and outer ring material

Material of the rolling element (i.e. the balls or rollers)

Material of the cage (the cage holds the rolling elements in place)

Material from which the bearing seal is made.

Type of lubrication of the rolling bearing. Rolling bearings are usually either greased, oiled or dry.
