GC20000 Series 300 Degree Medium and High Speed Spherical Roller Bearing
product details

One. Product and Technology Introduction

This series of products is a medium temperature high speed open load spherical roller bearing with a temperature resistance of 300 degrees. The minimum inner warp is 25 mm, the maximum outer diameter is 3.6 meters, and the highest accuracy is P4 level. The maximum use speed is 2000 rpm, or the outer ring linear speed is not greater than 1000 meters / minute.

This series of bearings, for general high-temperature bearings, require high temperature resistance, the speed of use is generally not very high, the cost is not very high, and they have good economic and technical properties, so they are widely used.

It consists of an inner ring, an outer ring, a rolling body, and a cage. The working characteristics of this type of bearings are that they can be changed at a certain angle during operation and can still operate normally. However, for high-temperature spherical roller bearings, because the bearings are processed at normal temperature, they work at 300 degrees. In this way, the bearing must inevitably generate thermal expansion and contraction in a 300-degree environment, which changes the normal motion trajectory of the original bearing, resulting in movement errors, which leads to incorrect meshing movement or additional stress. Service life, and even the bearing "seize" phenomenon during work, can not work properly. In view of the above problems, in order to improve the quality of bearings, we use a combination of thermodynamics and optimized design to establish a thermal finite element mathematical model, which successfully solves the theoretical correct trajectory under the premise that the inner and outer rings are not completely symmetrical, so that high temperature bearings At the rated temperature, the working condition is the same as that of the normal temperature bearing, which achieves the purpose of smooth running, long life and not "seizing" the bearing. The high-temperature grease with high temperature resistance and low evaporation is added inside, which can continuously run at high temperature and high speed, which reduces the vibration and self-heating loss of the bearing during high-speed operation and maximizes the service life.

two. Features

1.Cage structure is adopted, which is suitable for medium and high speed operation.

2. Stable high temperature grease for longer life.

3. High temperature grease lubricant, not only resistant to high temperature, but also itself as a reducing agent, also plays a role in reducing friction.

4. Can withstand large radial and axial forces.

5. High temperature resistance, anti-gluing, stable lubricant performance and low loss.

6. This bearing is suitable for 300 degrees high temperature and high speed medium load dusty environment and difficult to maintain grease.
