What is the cause of corrosion in CEMA idler?
Clicks:2050 Date:11-21
CEMA idler is one of the most common types of rolling bearings. The basic type of CEMA idler consists of an outer ring, an inner ring, a set of steel balls and a set of holding structures. There are two types of CEMA idler types: single row and double row. The deep groove ball structure is divided into two kinds of seal and open structure. The open type means that the bearing does not have sealing structure, and the sealed deep groove ball is divided into dustproof seal and oil proof seal.
CEMA idler, the axial load of the bearing is too small, will make the ball and raceway between sliding, become the cause of abrasions. Large CEMA idler, especially the ball and cage weight, have this tendency.
Causes of corrosion
In many cases, the bearing will occur corrosion phenomenon, leading to bearing corrosion reasons are many, our daily life is the most common are the following factors.
1) due to poor sealing device, by water, dirt and other invasion;
2) bearings for a long time, more than the rust prevention period, the lack of maintenance.
3) the surface roughness of metal is larger;
4) contact with corrosive chemical medium, bearing cleaning is not clean, the surface has dirt stained, or with sweat hand contact bearings, bearing cleaning, not timely packaging or installation, long-term exposure and the air, by the air water invasion and contamination;
5) environmental temperature and humidity and contact with various environmental media; rust inhibitor failure or quality does not meet the requirements.
