GD50000M series 500-degree low-speed heavy-duty self-lubricating thrust ball bearing
product details

One. Product and Technology Introduction

This series of products is a self-lubricating thrust ball bearing with a temperature resistance of 500 degrees and a low-speed, heavy-duty full-load ball. The size range is 15 mm inside diameter to 2 meters outside diameter, and the highest precision is P4.

The so-called high-temperature self-lubricating bearings are high-temperature bearings that rely on special components inside the bearings to achieve high-temperature lubrication without relying on external lubrication.

High-temperature self-lubricating materials must have physical and chemical properties that do not change under high-temperature environments, have thermal lubrication, and do not cause "evaporation" under high-temperature environments. Solids are ideal. The most common and common task is graphite. Graphite is characterized by simple manufacturing process, high temperature and corrosion resistance, stable physical and chemical properties under high temperature environment, low cost, and good lubrication effect.

There is another process to achieve bearing self-lubrication, which is to infiltrate the relative sliding surfaces of the bearings, to achieve the purpose of oil-free self-lubrication of the relative moving surfaces of the bearings. This process can also make the bearings work in an oil-free state for a long time, with good lubrication effects Long life, suitable for high-speed operation, but this process is more complex and higher cost, and is generally used in important machinery, military, aerospace and other industries. We can supply the above two kinds of high temperature lubricating bearings.

This series of products is mainly composed of graphite self-lubricating. It consists of inner ring, outer ring, rolling elements and graphite blocks. It does not require a cage. It uses a full-loading rolling element structure. The number of assembled rolling elements is greater than the maximum number that can be installed. One less, in the rolling body space, symmetrically or basically symmetrically assemble two graphite blocks (in the circumferential direction, keep the distance between the two graphite blocks to maximize), the two graphite blocks revolve with the steel ball and wear some graphite powder into The channel acts as a lubricant. When the bearing stops rotating, it also stops abrasion, and the lubrication and consumption are synchronized.

The biggest weakness of high-temperature bearings is the unsatisfactory lubrication, which is always a problem. When high-temperature grease is added in time, it will dry out for a period of time. Either stop and add grease or run without lubrication. This series of products uses graphite solid lubrication, graphite will not degenerate under high temperature environment for a long time, will not be automatically lost by heat, and maintain high temperature lubrication performance, high temperature resistance, uniform lubrication, long life, and avoid using high temperature grease to evaporate in high temperature environment Grease and refill with high temperature grease.

two. Features

1. Full ball structure is adopted, with large bearing capacity, which is 1.4 times that of ordinary bearings.

2. Lubricated with solid graphite powder, no sticky matter is generated.

3. Graphite is stable, graphite powder is produced and lubricated simultaneously, and its service life is long.

4. Adopting a sealed structure to prevent dust and stickies from entering.

5. High temperature resistance, anti-glue, long life, no need to add any lubricant in the whole process of use.

6. The dust cover is made of stainless steel, and no rust powder is generated in the high temperature environment, realizing maintenance-free.

7. This bearing is suitable for high-temperature, low-speed, heavy-duty, dusty environments, and difficult to maintain grease.

three. Technical Parameters

1. Model: GD50000M

2. Appearance size: same as corresponding standard bearing size

3. Size range: minimum inner diameter 15 mm, maximum outer diameter 2 m

4. Durable temperature resistance: 500 degrees, peak temperature resistance: 600 degrees (for 8 hours)

5. Maximum speed: 200 rpm or the linear speed of the outer diameter is not more than 100 m / min

6. Dynamic and static load: 1.4 times the load of the same model

7. Lubrication form: solid graphite self-lubricating

8. Structural seal: single row full ball maintenance-free (double-sealed structure can also be manufactured)

four. Precautions

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

2. High-temperature bearings, selected according to national standards, it is recommended to choose shaft f6, M7

3. In the process of selection, maintenance, installation and use, if you have any questions, please contact us directly.
