Only 25% of bearing performance depends on the quality of the bearing. Other factors, such as installation, lubrication and maintenance is actually the greatest impact on bearing life.
Improper assembly
All kinds of bearing failure in advance, 16% were due to improper assembly (usually due to excessive force ...) and not caused by the proper use of assembly tools. Some devices require the use of mechanical, hydraulic or heating method for proper and efficient installation and removal. Bearings offers a variety of professional engineering services technology based set of tools and devices, making these work easier, faster and more cost accounting benefits. Using special tools and techniques for professional assembly, is to achieve the maximum extension of the machine running time another solution.
Improper lubrication
Although you can install a variety of "maintenance free" sealed bearings, bearings fail prematurely but there are still 36% is due to the incorrect application of grease technology and improper use. Any improper lubrication of the bearings will inevitably fail in advance of normal life. Since the bearing is usually the most difficult mechanical handling equipment components, lubrication problem occurs infrequently. In the case of manual maintenance can not be achieved, the bearing lubrication system can be developed to achieve optimal automatic lubrication. As long as the bearing grease according to require the use of tools and techniques for effective lubrication, will help to significantly reduce downtime.
Pollution
Bearings are precision parts, if the bearings and grease contamination will not operate effectively. In addition, as has been marked with grease maintenance-free sealed bearings all use only a small portion of the bearing, so all the early failure of the bearing at least 14% is due to problems caused by pollution. TIMKEN bearings with excellent manufacturing and design capabilities, can provide a variety of harsh environments sealing solutions.
Fatigue
If the machine becomes overloaded, use or improper maintenance, the bearings will be affected, leading to premature failure of the bearing, 34% were due to fatigue caused by. Since the bearing in the maintenance of inappropriate or excessive stress would be given "early warning", you can use TIMKEN bearing condition monitoring equipment for testing and analysis, so sudden or unplanned failure can be avoided.
TIMKEN bearing life analysis of the main task is based on a lot of background material, analysis of data and failure modes, find the cause of bearing failure of the main factors in order to have targeted improvements to extend bearing service period, to avoid the occurrence of sudden bearing onset of early failure.
(A) to keep the bearing and its working environment clean.
Even the eyes can not see small dust, TIMKEN bearings will give a bad influence. Therefore, to keep the surrounding clean so that dust will not invade bearings.
(2), exercise extreme caution.
Bearing in use to give a strong impact, it will have a scar and indentation, cause of the accident. Severe cases, crack, fracture, it must be noted.
(3), using the appropriate operating tool.
Avoid the existing tools instead, you must use the right tools.
(4), to pay attention to the bearing corrosion.
Operation TIMKEN bearings, the hands sweat would become rusty cause. To pay attention to clean hands operation, the best possible wear gloves.
