Bearing knowledge: bearing SKF Bearings Inner Diameter http://www.skf-ball-bearings.com/ during operation of attention (bearing) operation:


Need to check the status of the operation of the machine, of which the bearing as the focus, and thorough examination of preparatory plan has been more and more important. Because it is the most important of all the machines rotating parts, condition monitoring is an important part of the preventive care, early detection of bearing damage to prevent due to bearing damage caused by the unscheduled maintenance equipment during outage.


Current market has been quite a number of systems and equipment, especially the importance of a machine or bearing in harsh environments should always check. Used to monitor the bearing, the instruments are mostly based on the measurement of vibration.


Not all the machines are equipped with the advanced instruments, however. In this case, the machine operator or maintenance engineers have to bearing fault signal insist on high alert, such as noise, temperature and vibration. Touch [listen to] [] [watch] three important factors, the following views can be provided for your reference.


The cautions of bearing during operation Listen to:


Examples with the aid of electronic stethoscope check feel a part of abnormal noise is experienced operator use. If the bearing is in good operation condition will be low purring sound, using the hearing to identify irregular operation is a very common method. If a sharp hissing sound, make sound, and other irregular {TodayHot} generally represent bearing in the operation condition of bad.


And lead to sound like the coo of a smooth, high-pitched squeaky noise may be caused by improper lubrication caused by inadequate bearing clearance can cause metal sound. Bearing outer ring grooves on the tracks will cause vibration. If knock scars caused when the device also can produce noise, the noise will be along with the bearing rotating speed of high and low. If there is intermittent noise, said rolling parts may be damaged, this voice is happens when the damaged surface is rolled out, bearing inner if pollutants often causes hissing sound, serious damage of bearing can produce irregular and big noise.


But usually at this time has been to the bearing must be replaced immediately. So, bearing damage is by listening to. Better methods used such as electronic condition monitoring instrument, for example, the workings of the diagnostics of bearing in advance.


The other end of the stick to the ear, the use of advanced equipment more accurately estimate the bearing condition. Compared with old method, using a wooden stick or a screwdriver on the bearing housing



Linear ball bearing installation and adjustment of eight steps:


1, before the assembly, bearing the daub after internal must clean grease.


2, bearing pressure into the bearing seat, should use special installation tool pressure by outer end face, do not allow direct knock bearing, so as to avoid deformation.


3, guide shaft load bearing, gently insert should aim at center. Such as insert askew, can make the ball fall off, keep frame deformation.


4, bearing load bearing seat, the rotation is not allowed to make its turn, will damage the bearings.


5, are not allowed to use check screw set on the bearing outer ring directly, otherwise it will occur deformation.


6, gather, closed and open installation, and then screw clamp, is used to adjust clearance, be careful not to make the preloading is too large.


7, linear ball bearing seat of installation.


8 and the fixed methods for linear ball bearings.
