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
