The difference of high-temperature bearings between 500 ℃ bearings and 1000 ℃ bearings
Posted by Edison Yang on
As we all know, 500 ℃ bearings and 1000 ℃ bearings belong to high-temperature bearings, so what is the difference between them? Which temperature range bearings need the help of good partner lubricating grease more? Next, I will briefly introduce them to you
1、 High temperature bearing
As the name suggests, high temperature bearing is a kind of bearing that can withstand high temperature. There are many kinds of bearings. Different types of bearings can be installed in different needs and different use environments.
2、 Whether to add oil to high temperature bearing
The excellent performance of high-temperature bearings in the operation process cannot be separated from the good bearing operation environment given by high-temperature bearing grease. However, when the bearing temperature reaches more than 500 ℃, imported or domestic high-temperature grease can basically not meet the use requirements
According to whether high-temperature bearings need to be lubricated with high-temperature grease, they can be divided into two categories. High temperature bearings +200 ~ +550 ℃ need to be lubricated with high-temperature bearing grease, and high-temperature bearings +550 ~ +1400 ℃ need to be lubricated with oil-free self lubrication due to the characteristics of profit materials. High temperature bearings do not need to be lubricated with high-temperature grease.
3、 Should the high temperature bearing be refueled?
Sliding bearings with sealing covers on both sides do not need to be lubricated. (whether rubber sealing cap or stainless steel sheet stamping sealing cap) the required high-temperature grease has been filled long before the high-temperature bearing leaves the factory, so the new high-temperature bearing does not need to be filled with high-temperature grease, but it still needs to be filled with high-temperature grease in later use, which can prolong the service life of high-temperature sliding bearings.
The filled grease and the filling amount of grease are all through continuous tests and tests, and the best mean value is calculated in the later use, which is the best and most scientific scheme. Therefore, generally speaking, the loss service life of high-temperature bearing grease is equivalent to that of high-temperature sliding bearing. After using for a period of time, add the high-temperature grease specified by the manufacturer, which is conducive to the durability of high-temperature bearing.
4、 High temperature bearing grease
It refers to a composite soap thickened semi synthetic lubricating oil, which is made by adding structural improver, antioxidant preservative and special anti-wear preservative. High temperature bearing grease has the following functions: good high temperature characteristics and air oxidation stability, which can prevent the lubricating oil from deteriorating at high temperature and ensure the long-term use of lubricating parts at high temperature; Good adhesion and mechanical equipment stability, as well as colloidal stability, can be guaranteed in lubricating parts; Good lubricity can protect high-temperature sliding bearings and reduce wear; The comprehensive performance is strong, which can ensure the long service life of the sliding bearing.
To ensure the effectiveness of high-temperature lubricating grease: high-temperature lubricating grease should be stored in a cool and dry place to prevent the infiltration of moisture and impurities from affecting the product quality.
High temperature bearings are mostly used in aerospace, military industry, chemical industry, heat treatment and other mechanical equipment that need high temperature operation or spontaneous high heat. High temperature resistant bearings are difficult to distinguish with the naked eye. Some regular high temperature resistant bearings are marked on the parts, such as gear marks, top marks and other assembly marks, to ensure the correct installation of the machine parts. Please buy carefully.
