Composite bearings are fine parts, so use very cautious. Even
with sliding bearings with high performance composite bearings, if used
improperly, it can not reach the expected performance results, but also
easy to damage the bearings. Therefore, the use of bearings should pay attention to the following:
First, insist on the bearing and the surrounding environment clean,
even if the naked eye can not see the copper alloy sleeve bearings into
the bearing dust, but also increase the bearing wear, vibration and
noise.
Second, the use of devices should be carefully and carefully, does not
allow strong punching, not allowed to hammer directly on the bearing,
not allowed to pass the rolling body pressure.
Third, the use of appropriate, accurate installation tools, try to use
special tools, to prevent the use of cloth and staple fiber and the
like.
Fourth,
to avoid bearing corrosion, directly take the bearings by hand, wash
your hands full of sweat, and sliding bearings coated with high-quality
mineral oil and then stop operation, especially in the rainy season and
summer should pay attention to rust. However,
under some special operating conditions, the bearing can achieve more
than the traditional calculation of life expectancy, especially at light
load conditions. These
special operating conditions mean that the rolling surfaces (rails and
rolling elements) are effectively separated by a smooth film and the
appearance of damage that can be caused by the contaminants is limited. In fact, under the ideal conditions, so-called eternal bearing life is possible.
Fifth,
the bearing life, the life of the bearing in revolutions (or the number
of hours of work under a certain speed), the definition: Bearings
within this life expectancy should be in any of its bearing ring or
rolling body made the initial fatigue damage Flaking or missing). However,
both in laboratory experiments or in theory, it is obvious that under
the same working conditions, the appearance of the same bearing, the
theoretical life expectancy is very different. There
are several different definitions of bearing "life", one of which is
the so-called "working life", which means that the theoretical life
expectancy of a bearing before it is damaged is due to wear, which is
usually not caused by weariness but rather By the wear and tear, corrosion, seal damage and other reasons.
