We then look at the influence of temperature on the bearing.

Often expressed with high temperature bearings in unusual circumstances. Temperature is harmful TIMKEN angular contact ball bearing lubricant. Sometimes bearing overheating can be attributed to the bearing lubricant. If the bearing temperature over 125 ℃ even move to reduce long bearing life. Caused by high bearing the following reasons: lack of lubrication or excessive lubrication, lubricant. Containing impurities, the load is too large, the bearing ring damage, lack of space, and produce high-friction seals and so on.
Therefore, continuous monitoring of bearing temperature is necessary, whether it is measuring the bearing itself, or other important parts. If the operating conditions remain unchanged in the case of temperature change can be said of any fault has occurred.
Bearing temperature measured by means of a regular thermometer, such as digital thermometers, bearing temperature can be accurately measured and determined in accordance ℃ or Fahrenheit units. The importance of bearing, which means when it is damaged, can cause equipment downtime, so this type of TIMKEN bearings should preferably be installed temperature probes.Left hand holding the bearing sleeve bearing the body, right hand to rotate toggle coat, listen to whether there is a hybrid ring. As most of the counterfeit products behind the production conditions, completely hand-mill operation in the production process will inevitably distracted sand a class of impurities, TIMKEN bearings hidden in the body, so the rotation will be issued when hybrid ring. This is strictly enforced and production standards, and with the machine operation is the biggest difference between brands.
Bearing this in the purchase should pay special attention. Because of the current anti-rust technology is not particularly home, so the bearing body rust treatment can easily leave traces of oil thick, sticky thick stick in your hand, while the foreign original bearing almost invisible rust oil traces, it touches especially careful expert said bearing smells kind of taste, is certainly under anti-rust oil, but do not see it.
TIMKEN bearings called chamfer, which is horizontal plane and the vertical plane of the junction, counterfeit bearings due to production technical limitations in these corners of the site handled unsatisfactory.
Vibration of the bearing damage can be quite sensitive, peeling, creasing, corrosion, cracks, wear, etc. will be in the bearing vibration measurement reflected. So, by using a special bearing vibration measurements (frequency analyzer, etc.) to measure the size of the vibration, frequency points can not be inferred abnormal circumstances. The measured values ​​due to the conditions of use or the bearing sensor mounting location is different, so each machine needs prior to analysis and comparison of the measured values ​​determined criteria.
