There are many types of FAG imported bearing angular contact ball bearings; the normal heat treatment process of angular contact ball bearings with an outer diameter of less than 240mm ensures that it is stable at temperatures below 150 degrees. For example, operating temperatures above 150 degrees require unique heat treatment; The ball bearings are suffixed with S1 to S4 (DIN 623) symbols. S1: Maximum operating temperature 200 degrees S2: Maximum operating temperature 250 degrees, S3: Maximum operating temperature 300 degrees S4: Maximum operating temperature 350 degrees When the outer diameter is greater than 240mm FAG Angular touch ball bearings typically maintain a stable scale below 200 degrees.
There are also several conditions:
1. The angular touch ball bearing is made of glass fiber reinforced nylon 66; it is suitable for the stability of working temperature not exceeding 120 degrees; when the angular touch ball bearing uses oil smooth; if the oil contains additives; can cause the cage The service life is shortened. When the temperature exceeds 120 degrees, the aging smooth oil will shorten the life of the cage. Therefore, it is necessary to investigate and replace the smooth oil on schedule.
2, FAG bearing seal angle touch ball bearing allowable temperature also depends on the life of the smooth grease filled between the need and touch seal requirements. Sealed angular touch ball bearings using a unique test of high quality lithium-based smooth grease Smooth. This smooth grease can accept a high temperature of 120 degrees in a short time. If the operating temperature reaches 70 degrees or higher, the life expectancy of lithium-based smooth grease will be shortened.
3, to always work at high temperatures, it is necessary to use a unique smooth grease; and also pay attention to the need to use heat-resistant materials as a sealing device. The standard operating temperature of the touch seal can not exceed 110 degrees.
4. If the high temperature composition data is used for sealing; then it is necessary to think that this very useful fluorination data will emit harmful gas and smoke when it exceeds 300 degrees. The unique use of the FAG bearing angle touch ball bearing is to be used. When welding a gun; pay more attention to this.
