GENA Series 500 Degree Medium and High Speed Needle Bearings
product details

One. Product and Technology Introduction

This series of products is a high temperature and medium load open needle roller bearing with a temperature resistance of 500 degrees and a cage. The minimum inner warp is 5 mm, the maximum outer diameter is 3 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 and a rolling body, and a cage is required.

This type of high-temperature bearing adopts high-temperature resistance and high-speed optimized design, 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. The flanges and raceways of this type of bearings are all refined, which improves the accuracy and stability of the bearings.

High-temperature and high-speed bearings require high-temperature grease during operation to increase service life.

two. Features

1. Adopting the structure with cage, researching the flange and raceway technology and the design of hyperbolic trimming structure, the bearing capacity is large and the operation is stable.

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, high-speed, medium-load and dusty environments and difficult to maintain grease.

three. Technical Parameters

1. Model: GENA0000

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

3. Durable temperature resistance: 500 degrees

4. Peak temperature resistance: 600 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: single row open maintenance-free with cage

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.
