Ina combined needle roller bearing clearance change failure maintenance technology

Maintain good bearings is the essential condition of ina combined needle roller bearing is running, the commonly used maintenance is for bearing lubrication, in reading how to select the bearing lubrication method, under the premise that knowing bearing lubrication method, it is necessary to know about bearing system maintenance is also, let's look at how to make the bearing lubrication maintenance. A, use when installation should careful not allowed powerful punch, ina bad phenomenon in a combined needle roller bearing solutions are not allowed to use hammer percussion 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. 3, try to keep ina combined needle roller bearing and the surrounding environment clean motor bearings commonly used sodium base grease dust into the bearing even invisible to the naked eye smile, also can increase the bearing wear, vibration and noise. Four, to prevent rusting ina combination of needle roller bearing 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, ina combined needle roller bearing can get more than the life of the traditional computing, especially in the case of light load. Bearing box of labyrinth seal mechanism and influence factors analysis of the specific operating conditions is, when the rolling bearing 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. Lubricant is important not only for bearing, also for all of the bearing. But please note that ina combined needle roller bearing shoulds not be too much grease. And then replace the bearing lubricant. Use after xie used engine oil, engine oil lubrication bearing if possible, should be impregnated with fresh oil and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil. And the use of grease lubrication bearing in replacing grease, Joe used in addition to the device should be avoided with any part of the cotton material come into contact with the bearing. Because these residues fiber may wedged in between the scroll and damage, especially the application of bearing more need to pay attention to this problem.
