GCQJ series 300 degree medium and high speed four point contact ball bearing
product details

One. Product and Technology Introduction

This series of products is a high temperature and medium load four point contact ball bearing with a temperature resistance of 300 degrees. The minimum internal warp is 10 mm, the maximum outer diameter is 3.6 meters, and the highest accuracy is P5. The maximum use speed is 2000 rpm, or the outer ring linear speed is not more 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 high-temperature four-point contact ball bearings is that the two parameters are completely the same, otherwise it will cause uneven force early failure. We use three-dimensional simulation precision machining technology and high 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. All steel balls bear the load completely at the same time, with large bearing capacity and long service 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: GCQJ6205ZZ

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

3. Durable temperature resistance: 300 degrees

4. Peak temperature resistance: 400 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 single 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.
