One. Product and Technology Introduction
This series of products is a low-speed heavy-duty open needle roller bearing with a temperature resistance of 500 degrees and full load rollers. The minimum internal warp is 5 mm, the maximum outer diameter is 3 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, and rolling elements. It does not require a cage. It uses a full ball structure. The number of balls is 50% greater than that of ordinary bearings.
This type of high temperature bearing adopts the optimized design of high temperature resistance, so that the high temperature bearing at the rated temperature, the same working condition as normal temperature. In addition, the slight deformation of high-temperature bearings in high-temperature environments will cause bearing stress concentration or decrease in bearing capacity. In order to eliminate these deformation effects, we manufacture both ends of the rollers into hyperbolic repairs Edge structure, this structure can not only eliminate the angular error of the shaft, but also eliminate the stress concentration caused by thermal deformation and prevent early failure. After many years of practice, this type of roller high temperature bearing has a longer service life and more Large carrying capacity and better running stability.
High temperature and low speed bearings can run normally without adding high temperature grease, but adding high temperature grease will increase the service life.
1. It adopts full-roller structure and hyperbolic trimming structure design, with large load carrying capacity, which is 1.4 times that of ordinary bearings.
2. Lubricated with high temperature grease, no sticky matter.
3. High temperature grease Kang has high temperature evaporation ability and long life.
4. Can withstand large radial force and certain axial force.
5. High temperature resistance, anti-glue, can offset the stress caused by thermal deformation, and prevent the early failure of the bearing.
6. This series of bearings are suitable for high-temperature, low-speed, heavy-duty, dusty environments and difficult to maintain grease.
