We recently found that many users have been consulting our high temperature bearings, but a closer question only to find that the user does not need high temperature bearings, the ordinary bearings can meet the requirem ents, to be seen what is the difference between plain bearings with high-temperature bearings? General thrust ball bearings can withstand the maximum temperature? Are not very understanding, we bearings for example, explain this problem.double row ball bearing
 Typically, the working temperature above 150 ° bearings known as high-temperature bearings, chromium bearing steel its hardness to a sharp decline in the temperature exceeds 150 °, dimensional instability, thrust ball bearings can not work properly. Bearing working temperature of 150 ° to 350 °, if the rings and rolling elements still use ordinary carbon chromium bearing steel manufacturing, must be tempered special bearing parts, should generally be higher than the operating temperature 50 ° tempering. After processing by the above requirements tempering of bearing steel, at the operating temperature under n ormal use. But tempered hardness decreased, reduced bearing life. When the bearing operating temperature higher than 350 °, you must be using a high temperature bearing steel manufacturing.
High temperature bearings addition to just the general bearing steel performance, you should also have a certain high temperature hardness and high wear resistance, high temperature and relieve fatigue strength, oxidation resistance, high temperature resistance impact resistance and high temperature dimensional stability.
When bearing rotation, thrust ball bearing inner ring and outer ring raceway and rolling element rolling contact, thus running track for the dark side of the running track attached to the raceway is not abnormal, thus becomes available learned that the load conditions, when demolition bearing strict attention and observe the trajectory of the raceway.
The bearing is installed correctly, affect the accuracy, life, and performance. Therefore, the design and assembly departments should fully study for the installation of the bearing. To be installed in accordance with the operating standards. Operating standards of the project is usually as follows:slim bearing
(1), cleaning bearings and bearing components related to
(2), check the connected components of size and finishing
(3), the installation
(4), installed after the inspection of the bearings
(5), supplying lubricant
Shortly before installation, open bearings packaging. General grease lubrication, cleaning, directly populate grease. Lubricating oil, Common without cleaning, However, the equipment used or the high speed with a bearing, etc.,
Use clean oil washed to remove the coating thrust ball bearings rust inhibitor. A rust inhibitor bearing is removed, easy to rust, and therefore can not be placed in the air. The grease-sealed bearings can be used directly without cleaning.
