TIMKEN bearing corrosion causes and prevention measures

INA bearing itself from the overwhelming proportion of metal corrosion, because of the needs of work, a lot of the time this is inevitable. Contact bearings, hand sweat can also cause INA bearing corrosion, mainly is the sweat contact bearings will produce sweat film on its surface, interaction leads to the corrosion electrochemical reaction, but this is to avoid, such as the professional take parts of tools such as gloves. Metal corrosion reason of TIMKEN bearing is mainly where the points: 1, the surface finish; 2, metal materials, chemical structure and composition; 3, metal surface composition and PH value of solution; 4, environmental medium; 5, the surrounding humidity and temperature. TIMKEN bearing corrosion prevention measures are mainly: keep the bearing surface is clean, clean and must use the appropriate method. General chemical treatment methods such as cleaning, mechanical cleaning, and a solvent cleaning. Available after surface clean, dry compressed air blow dry, also can use 120 ~ 170 ℃ dryer to dry, then dry with a clean cloth. Finally again to bearings coated with anti-rust oil, details are as follows: using immersion method, the temperature of the oil film thickness can be controlled by anti-rust oil or viscosity to achieve. Some small items by soaking in antirust oil, make its surface adhesion on a layer of anti-rust oil; Dana, Mr. Gao by using the method of spray on some big rust cannot take immerse oil, rust-proof oil is suitable for thin layer or solvent XiShiXing anti-rust oil, but should pay attention to labor and fire protection measures; When using a brush, brush besmear to avoid do not produce accumulation, not only to prevent leakage caused by the coating. Apply to not share soaking or spraying some special shape products or outdoor building equipment. A, use when installation should careful not allowed powerful punch, are not allowed to use hammer percussion TIMKEN bearing directly, not allowed by transfer roller pressure. 2, using appropriate and accurate installation tools use a special tool, as far as possible to avoid use cloth class and short fiber, things like that. Third, try to keep the bearing and the surrounding environment clean dust into the bearing even invisible to the naked eye smile, also can increase the bearing wear, vibration and noise. Four, to prevent rusting of the bearings directly with the hand take bearing, to fully wash hands sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust. In some special operating conditions, can obtain a longer than traditional computing by TIMKEN bearing life, especially in the case of light load. These special operating conditions is, when the rolling surface ( Track and rolling piece) Can be separated by a lubricating oil film effectively and the surface of the limit of pollutants may cause damage. In fact, under ideal conditions, the so-called permanent bearing life is possible.
