TIMKEN bearing wear is divided into two categories, one is the abrasive wear, and the other is adhesive wear. These two types of wear of induced by different reasons, but are issues of motor bearings are often encountered.
1, abrasive wear
Abrasive wear is because between the rolling elements and raceways due to some impurities exist and acts as an abrasive character, and wear between the raceways and rolling elements. Which is characterized by material wear and tear of rolling elements or raceways. Such worn mostly as a result of pollution caused by the impurities into the lubricant poor lubrication.
2, adhesive wear
Second motor TIMKEN bearing wear is occurring frequently in adhesive wear. Adhesive wear and abrasive wear different, most accompanied by transfer of metal materials, such as from rolling to rolling road or vice versa. TIMKEN bearings in the motor internal adhesive wear there are a lot of ways, especially in the frequently starting motors, motor starts and stops frequently (or reciprocating rotation) greatly increase when moving between the rolling elements and raceways of sliding friction, thus very vulnerable to adhesive wear. Adhesive wear of the response to this situation, by improving lubricants (such as for the operation of reciprocating motor grease adds extreme pressure additives) and other methods to reduce the starting stopping within the bearing sliding friction.
