Bearing damage repair and maintenance methods

Damage to the bearing investigate and deal with the causes, in the short term and take the appropriate measures, SKF bearings damage situation is much more complicated than general mechanical parts damaged, the characteristics of the bearing damage is manifested in the form of more complicated because, in addition to bearing design and manufacture the internal factors, mostly due to improper use.
Quality and external conditions during use due to its carrying capacity, rotational accuracy and antifriction can performance change, When the the nsk bearings performance is lower than the requirements and does not work properly, it is called the bearing damage or failure, bearing unforeseen circumstances the event of damage, etc., will stall its machinery, equipment, function subject to injury and other anomalies.
Select the appropriate fag bearings correctly grasp the premise of bearings in the use of parts of the mechanism and conditions of use and environmental conditions are suitable bearing. Whom need to obtain the following data and information:
(1) the function and structure of the mechanism
(2) ian use of bearing parts
(3) bearing the load (size, direction)
(4) the rotational speed
(5) The vibration, shock,
(6) The bearing temperature (ambient temperature, temperature rise)
(7) surrounding atmosphere (corrosive, cleaning, lubrication)
It is important to first maintain the timken bearings lubrication and clean. So when we check the bearings before, you should first clean the bearing surface, then remove the bearing surrounding parts. Pay attention to the oil seal is very fragile parts, so need to be extra careful inspection and disassembly Do not use excessive force, in order to avoid damage to the parts. Then carefully check the bearing oil seal and its surrounding parts, have shown adverse symptoms must replaced, poor seal can cause damage to the bearing, the bearing cloud like not normal equipment downtime.
