GV4000ZZ Series 800 Degree Medium and High Speed Double Row Deep Groove Ball Bearing
product details

One. Product and Technology Introduction

This series of products is a medium- and high-speed double-row deep groove ball bearing with a temperature resistance of 800 degrees. The minimum inner warp is 10 mm, the maximum outer diameter is 3.6 meters, and the highest accuracy is P6. The maximum operating speed is 2000 rpm, or the outer ring linear speed is not greater than 1000 meters / minute. It consists of an inner ring, an outer ring, a cage, a high-temperature grease and rolling elements.

The key technology of double row deep groove ball bearings is that the parameters of the two channels 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. Sometimes the cage will break. 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.

High-temperature and high-speed bearings must be added with high-temperature grease during operation to increase service life.

two. Features

1. With cage structure, adapt to high speed.

2. Lubricated with high temperature grease, no sticking matter is generated, which prevents the early failure of the bearing.

3. The double-row steel balls can bear the load at the same time, with large bearing capacity and long life.

4. Can withstand large radial and axial forces.

5. This series of bearings are suitable for high-temperature, medium-speed, heavy-duty, dusty environments and difficult to maintain grease.

three. Technical Parameters

1. Model: GV4000ZZ

2. Dimensions and tolerances: Dimensions and tolerances are the same as national standards and are interchangeable

3. Durable temperature resistance: 800 degrees

4. Peak temperature resistance: 900 degrees

5. Maximum speed: 2000 rpm, or the linear speed of the outer ring is less than 1000 m / min

6. Dynamic and static loads: same as corresponding bearings of the same model

7. Lubrication form: high temperature grease lubrication

8. Structural seal: open / closed double row ball maintenance free

four. Precautions

1. The installation part is selected to be isolated from high heat and does not directly radiate the mechanical part.

2. Each bearing on the production line is evenly stressed.

3. High-temperature bearings are selected according to relevant national technical standards, or shaft f6 and seat M7 are recommended.

4. If you have any questions during use, please contact us.
