Under a certain load, the number of revolutions or hours experienced by the bearing before pitting is called the bearing life.The main factors affecting bearing life are as follows:
I. Material characteristics;It is mainly restricted by the hardness, strength, toughness, wear resistance, corrosion resistance and internal stress state of steel.
II. Improper installation (about 16%)
1. When installing, the force is too strong, and hammering the bearing is the biggest damage to the bearing.
2. The installation deviation or the bearing position is not installed, resulting in too small bearing clearance.
III, pollution will also lead to premature bearing damage, pollution refers to dust, metal chips and other into the bearing interior.
IIII, according to the investigation, poor lubrication is one of the main reasons for premature damage of bearings.Including not filling lubricant or lubricating oil in time;Lubricant or lubricating oil is not filled in place;Improper selection of lubricants or lubricants;Incorrect lubrication and so on.
IIIII. Fatigue damage is a common damage mode of bearings.The common causes of fatigue damage may be: long-term overload operation of bearings;Not timely maintenance;Improper maintenance;Equipment aging and so on.
