Note that the installation force. Such as raceways exposed interval of the pressure pit, indicating that the load has crossed the limit of elasticity of the material. This is because the static reproduced or severe shock (such as the installation had to beat with a hammer-aligning ball bearings, etc.) invocation. Accurate way of installation is only pressing force of the loop (not in the axis actor makeup inner push the outer ring).
Note the installation direction of the aligning ball bearings. timken bearings have a circular contact area, and only progress at a party to bear the axial thrust. Due to ball in the opposite direction of actor assembly of aligning ball bearings, living in the raceway edge of its contained surface initiation groove wear with. Accurate installation directions in the installation should pay attention.
Note pair. The ball wear remnants of deflection, and the direction of the raceway parallel indicates that the installation, aligning ball bearing is not right in the. If the deflection is> 16000, it is easy to motivate self-aligning ball bearing temperature rise up and exposed to severe wear. Initiation CMU may be the axis of buckling, shaft or box axis relative to vertical and other glitches, lock compression surface of the mother is not with the turnbuckle. Because of this, the installation should pay attention to the investigation of path hop thing status.
Should be noted that accurate and appropriate. Aligning ball bearings, the contact surface of the outer ring assembly revealed wear or discoloration of the circular-shaped aligning ball bearings with matching parts suitable loose invocation. Abrasive initiation of oxygen compounds is a pure brown natural abrasive, and its final results will lead to further aligning ball bearings wear, hair, warm initiation noise and the initiation of diameter jump and a series of questions, because this assembly should be accurate appropriate.
Another example is the bottom of the raceway serious spherical wear track, which indicates that smaller due to the appropriate tight-aligning ball bearing gap, because the torque increases, aligning ball bearing temperature rise up, timken bearings quickly because of wear and fatigue to be effective. At this point, as long as appropriate to restore the radial gap, detract from the amount of interference can solve this problem.
Normal fatigue ineffective. No matter what the appearance of a functioning (such as roller or ball) revealed irregular material spalling, and gradually extended-induced amplitude increase, which is a normal tired ineffective. If the useful life of the ordinary timken bearings survival, can not be satisfied with the performance requirements of only the new selection of more advanced aligning ball bearings, or growth of a bearing specifications to growth-aligning ball bearings, bearing experienced.
The lubricant inappropriate. All Gulu timken bearing demand purposes of uninterrupted high-quality lubricating agent lubricating oil, in order to maintain the preset performance. Aligning ball bearings depends on a layer of film formed on the the Gulu body and the seat to avoid direct contact between the metal and metal. If the lubricant is satisfactory, you can detract from the friction, so that it will not wear.
timken bearing in operating conditions, the viscosity of the lubricating grease or lubricating oil is critical to protect their normal lubricant; the same time, the lubricating grease to maintain cleaning, excluding solid or liquid impurities is also to shut closed. Oil viscosity is too low, can not fully enjoy the interests of oil from utility to quickly wear seat. When to proceed, the metal seat the Gulu body of metal table face each other directly contact friction, so that the appearance of polished Guangliu the  subsequent dry friction the  caused the fracturing seat appearance Gulu body the appearance of crushed grain crumbs. The original can look carefully at the appearance darken miss the luster, and ultimately the formation of dents and sheet fatigue stripping. Make up the method in accordance with the aligning ball bearing demand new selection Gaiyi the lubricant oil or grease.
Pollutants particulate contamination in lubricating oil or grease, even though these pollutant particles smaller than the film thickness, but the particle is very hard the  will continue to the initiation of wear, and even ripped through the film, resulting in the initiation part of the stress-aligning ball bearing appearance, and therefore significantly reduced timken bearing years of survival. Lubricating oil or grease in the water liquid concentration to 0.01% even though small, can be completely reduced to half of the original survival-aligning ball bearing years. Flow is soluble in oil or fat, aligning ball bearings with Survival of years with the water concentration of the liquid to a sliding scale while tightening to reduce. Make up method is to swap the clean oil or grease; daily over leaching device should be installed to increase the tightly closed, storage, installation, attention to cleaning operations.
Corrosion. Roller, ball, to maintain the frame and inside the outer ring surface of the exposed red or brown blemishes, indicating timken bearing is exposed to corrosive liquids or gases in the initiation of corrosion ineffective. It will motivate the oscillation increases, exacerbated by wear, the increase in radial gap, pre-loaded to reduce the occurrence of fatigue ineffective Moreover, in the limit of things conditions. Make up the method is to make the liquid from the discharge or increase in the tightly closed groups and external aligning ball bearings Self-aligning ball bearings.
