One. Product and Technology Introduction
This series product is a double-sealed four-point contact ball bearing with a temperature resistance of 300 degrees and a low-speed heavy-duty stainless steel dust cover. The minimum inner warp is 15 mm, the maximum outer diameter is 5 meters, and the highest accuracy is P6. The maximum use speed is 200 rpm, or the outer ring linear speed is not more than 100 meters / minute.
It consists of an inner ring, an outer ring, a rolling element and a dust cover. It does not require a cage. It uses a full-ball structure.
The key technology of this type of bearing is that the two channel parameters are completely the same, otherwise it will cause early failure due to uneven force. We use three-dimensional simulation precision machining technology and temperature compensation technology to completely solve the technical problems of this type of high-temperature bearings, improve the bearing manufacturing accuracy, and greatly extend the service life.
Another common form of failure is excessive wear of the steel ball. After excessive wear of the bearing, the gap becomes larger and the vibration intensifies, especially at higher speeds. In addition to bearing lubrication, the main reason for the excessive wear of the steel ball is the geometric accuracy and material of the steel ball, as well as the vibration value. The surface of the steel ball is infiltrated to increase hardness and wear resistance. Anti-friction effect. In these key technologies and processes, we have special equipment guarantee. General high-temperature bearings use a speed of 100 rpm, and the maximum cannot exceed 300 rpm.
High temperature and low speed bearings can run normally without adding high temperature grease, but adding high temperature grease will increase the service life.
The dust cover is made of stainless steel, no rust powder will be generated when heated, no rust powder will enter the channel to participate in abrasion, and other dust will be effectively prevented from entering the channel.
1. Full ball structure is adopted, with large bearing capacity, which is 1.5 times that of ordinary bearings.
2. Lubricated with high temperature grease, no sticky matter.
3. High temperature, high precision, low vibration steel balls are used, and the bearing life is long.
4. Can withstand large radial and axial forces.
5. Adopting a sealed structure to prevent dust and stickies from entering.
6. High temperature resistance, anti-glue, prevent the early failure of the bearing.
7. Using stainless steel dust cover, no rust powder is generated in high temperature environment, realizing maintenance-free.
8. This series of bearings are suitable for high-temperature, low-speed, heavy-duty, dusty environments and difficult to maintain grease.
