One. Product and Technology Introduction
This series of products is a double-sealed ball bearing with a low temperature resistance of minus 60 degrees and a low-speed heavy-duty stainless steel dust cover. The minimum inner warp is 5 mm, the maximum outer diameter is 3.6 meters, and the highest accuracy is P5. The maximum use speed is 200 rpm, or the linear speed of the outer ring 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 common form of failure of this type of low temperature bearing is excessive wear of the steel ball, and the main cause of the excessive wear of the steel ball is that the radius of curvature of the steel ball is smaller than the radius of curvature of the channel, which makes the contact radius of the contact area of the steel ball smaller and stress concentration. Causes early failure. This design uses a near-curvature design, which makes the radius of curvature of the steel ball and the channel very close, the mutual contact area increases, and the bearing capacity increases in a near-square relationship. This is why the low-temperature bearings with a near-curvature design have a longer service life However, this bearing design also has a limitation in use, that is, the use of speed can not be too high, otherwise it will cause the channel to jam the steel ball, affecting the rotation flexibility, general high-temperature bearings use 200 rpm, the maximum can not exceed 500 rpm .
Low temperature and low speed bearings can operate normally without adding high temperature grease, but adding low temperature grease will increase the service life.
The dust cover is made of stainless steel, so that no foreign matter enters the channel to participate in wear, and in addition, it effectively prevents other dust from entering the channel.
1. Full ball structure and near-curvature design, large bearing capacity, 1.5 times that of ordinary bearings.
2. Lubricated with low temperature grease, no sticky matter.
3. Low temperature grease has strong anti-evaporation ability and long life.
4. Able to bear large radial force and axial force.
5. Adopting a sealed structure to prevent dust and stickies from entering.
6. Low temperature resistance, anti-glue, prevent the early failure of the bearing.
7. The stainless steel dust cover is adopted to achieve true maintenance-free.
8. This series of bearings are suitable for low-temperature, low-speed, heavy-duty, dusty environments and difficult to maintain grease.
