In our daily life, many people are familiar with bearings, but when it comes to more optimized bearings such as high-speed angular contact ball bearings, I believe that many friends feel a little confused. In fact, high-speed angular contact ball bearings are an important part of bearing series products. High-speed means that the angular velocity of the bearing is high. Even if the speed ratio of large and medium-sized bearings is 3000r/min, the angular velocity is relatively fast. Even if the small-sized bearing exceeds 10,000, the angular velocity Also slower. Therefore, for the development of lubricating grease, most of the lubricating grease will test the speed factor after it is developed, to measure whether the lubricating grease can be used as an important specification for high-speed bearings. So what are the differences in types and specifications of high-speed bearing grease? How to choose the type and specification of high-speed bearing grease? High-speed angular contact ball bearing grease is a special kind of grease, which stipulates that it has high wettability, low friction coefficient, ultra-low temperature rise, and good durability and other characteristics to meet the normal operation of high-speed bearings. . The effect of lubricating is to reduce friction and reduce damage, and lubricating with grease can take away the heat caused by friction, thereby reducing the temperature of the friction surface and having the effect of heat dissipation. When selecting grease for high-speed bearings, you must pay attention to the following factors. First, temperature, which has a great influence on grease. If the operating temperature of the machine in the natural environment is relatively high, heat-resistant grease should be selected. The second is the bearing speed ratio. The parts running at high speed not only heat up quickly but also have a high temperature, which will easily cause the grease to become thin and flow out. Therefore, when using it, it is advisable to choose grease with a relatively thick mortar consistency. Furthermore, it is the load. The size of the penetration of the grease is related to the load that can be accepted in use. If the load is larger, the grease with a smaller penetration (thicker mortar consistency) should be selected. If it bears both heavy load and impact Load, it is advisable to use grease with extreme pressure additives, such as grease with molybdenum disulfide rubber. Only when the torque is accurate can the rotation be stable! 37 years of professional production of high-speed angular contact bearings! (http://)
