--- W series high temperature oil-free bearing
product details

One. Product and Technology Introduction

This series of products is an oil-free bearing. It is oil-free or oil-free self-lubricating for selected bearings to meet customer-specific requirements, including normal temperature oil-free bearings and high-temperature oil-free bearings. Bearing types include deep grooves. Ball bearings, outer spherical bearings, angular contact ball bearings, tapered roller bearings, spherical roller bearings, spherical ball bearings, cylindrical roller bearings, needle roller bearings, etc. The bearing size is 2 mm-5 meters, the highest accuracy is P4 level, the use of speed can be divided into low speed, medium high speed, ultra high speed can be achieved. This product is oil-free treated on the basis of the previous process to form oil-free bearings or oil-free high-temperature bearings.

The main technology of oil-free bearings is to degrease the bearings. There are many ways to degrease the oil, mainly depending on the structure of the bearing and the requirements for the degree of oil-free. To ensure that the bearings do not rust, but also have a certain surface hardness. For oil-free self-lubricating bearings, there are more complicated processes on the surface, especially high-speed oil-free self-lubricating bearings.

There are many materials that can make oil-free bearings. Heat-resistant bearing steel, heat-resistant alloy steel, corrosion-resistant steel, stainless steel, high Cr and Ni steel are all ideal oil-free bearing materials.

Oil-free bearings and oil-free high-temperature bearings are widely used in aviation, military, aerospace, vacuum coating, pharmaceutical industry, railway, food machinery, etc.

two. Features

1. Adopt cage and full-ball structure, suitable for low, medium and high speed operation.

2. Some oil-free bearings allow the use of graphite as a lubricant and also reduce friction.

3. For graphite bearings that are not allowed to be polluted or high-speed bearings, infiltration technology must be used.

4. Able to withstand large radial and axial forces.

5. This series of products are suitable for any oil-free environment and difficult to maintain grease or oil-free occasions.

three. Technical Parameters

1. Model: High temperature bearing model suffix W, such as GC6306ZZW
