                              Caster and bearing life
In order to determine the standard of caster bearing life, the caster bearing life is connected with

reliability.

The service life of rolling caster bearing is defined in revolutions (or hours of operation at a certain

speed): the caster bearing within this service life shall have preliminary fatigue damage (peeling or

defect) on any caster bearing ring or rolling body. However, no matter in the laboratory test or in

actual use, it can be clearly seen that under the same working conditions, the appearance of caster

bearings is the same, and the actual service life is very different. In addition, there are several

different definitions of caster bearing "life", one of which is the so-called "working life", which means

that the actual life of a caster bearing before damage is caused by wear and damage, which is usually

not caused by fatigue, but by wear, corrosion, seal damage and other reasons.

Basic dynamic load rating
In order to compare the anti pitting bearing capacity of caster bearing, it is specified that when the

rated life of caster bearing is one million revolutions (106), the maximum load that can be borne is

the basic rated dynamic load, expressed in C. That is, under the action of rated dynamic load C, the

reliability of this caster bearing working for one million revolutions (106) without pitting failure is 90%.

The greater C, the higher the bearing capacity.

Rated service life: due to the difference of manufacturing accuracy and material uniformity, even if the

same batch of caster bearings of the same material and size are used under the same working

conditions, their service life is also different. If the statistical life is 1 unit, the longest relative life is 4

units, the shortest is 0.1-0.2 units, and the ratio of the longest to the shortest life is 20-40 times. 90%

of caster bearings do not produce pitting corrosion, and the number of revolutions or hours

experienced is called the rated service life of caster bearings.

For basic dynamic load rating
1. Radial thrust caster bearing refers to the radial component that produces pure radial displacement

2. Radial caster bearing refers to pure radial load

3. Thrust ball caster bearing refers to pure axial load
