1. The limit speed of NTN bearing The speed of NTN bearing is mainly limited by the temperature rise caused by the friction heating inside the bearing. When the speed exceeds a certain limit, the bearing will not continue to rotate due to burns. The limit speed of NTN bearing refers to the limit value of the speed at which it ca...

In automobile transmissions, most traditional systems use rolling bearings to support the rotating axle to ensure stable rotation of the rotating axle. The following example illustrates the use of NSK cylindrical roller bearings to support the stable transmission of the rotating axle. During use, NSK cylinders are found The inne...

1. High-speed grinding technology General production efficiency can be increased by 30%-60%, and the durability of the grinding wheel can be increased by about 0.71 times. High-speed grinding can achieve the two major goals pursued by modern manufacturing technology to improve product quality and labor efficiency. Practice has p...

1. Initial stage (1) The noise is normal; (2) The temperature is normal; (3) It can be measured by ultrasonic, vibration peak energy, and acoustic emission. The outer ring of TIMKEN bearing is defective; (4) The total amount of vibration is relatively small, and there is no discrete TIMKEN bearing fault frequency spike; (5) The ...

The assembly of TIMKEN bearings is an important part of bearing processing. The essence of assembly is to assemble the qualified bearing parts that have been processed by precision machining and meet the technical requirements of the bearing parts process into a finished bearing through certain methods and steps. The technologic...

In order to ensure the service life of NACHI bearings, it is necessary to process the bearings, such as forging processes; in order to obtain evenly distributed residual carbides in the finished parts of the bearing, and to ensure the wear resistance of the bearings, an annealing process is required; The carbon layer ensures the...

SKF and the University of Twente are combining their research expertise to drive advances in an area crucial to rotating machinery performance: grease lubrication. SKF and the University of Twente which have collaborated for over 30 years have launched a dedicated SKF University Technology Center (UTC) for grease lubrication in ...

(1) Surface oxide layer The steel surface under the action of instantaneous high temperature interacts with the oxygen in the air to form a very thin (20 ~ 30nm) thin layer of iron oxide. It is worth noting that the thickness of the oxide layer corresponds to the test result of the total thickness of the surface-modified metamor...

There are two most common ways to replace INA bearings: one is to directly heat INA bearings with acetylene oxygen; the other is to use oil immersion heating for small INA bearings to achieve thermal expansion and expand the inner diameter of INA bearings for assembly. These methods have been widely used in long-term equipment m...
