Material and lubrication

Mainly used materials:

Commonly used high temperature bearing steel are: molybdenum steel: Cr4M04V, Crl5M04, 9Crl8Mo, Crl4M04; tungsten steel: W9Cr4V2Mo, W18Cr4V; tungsten and molybdenum: W6Mo5Cr4V2. High temperature bearing steel W, Cr, V, Mo, etc., can form a difficult to dissolve at high temperatures of the carbides, and in the tempering of precipitation of diffuse distribution of carbide, the secondary hardening effect. Produce secondary hardening effect, so that such steel at a certain temperature still has high hardness, wear resistance, strong oxidation resistance, high fatigue resistance and dimensional stability. High-temperature bearing steel with Cr4M04V and W18Cr4V most commonly used.

High-temperature bearing steel: high-temperature bearing steel S1/S2/S3/S4 in addition to general bearing steel performance, but also has a certain high-temperature hardness and high-temperature wear resistance, high-temperature contact fatigue strength, oxidation resistance, high-temperature impact resistance and high-temperature performance stability. High-temperature high-speed steel, high-temperature powder metallurgy steel, 100Cr6, SUJ2, M50, SUS420, SUS440, KS440, SUS444, SUS304, SUS316L, 310S and a variety of high-nitrogen stainless steel, and other materials, according to the needs of the working conditions of the production of bearings made of different materials.

 

Ceramic material: zirconia, silicon nitride, silicon carbide ceramic bearings, ceramic material can be in the 1000 ° high temperature hardness is too large changes in low speed (according to the model and speed to decide) can be no lubrication work, but also with a variety of materials can be used in combination to solve the installation of ceramic bearings fragile drawbacks, but also high temperature.

Graphite: belongs to the commonly used high temperature lubrication material, used for 500 ° within the low-speed conditions, graphite cage bearings, graphite block lubrication bearings, graphite powder can be molded, attached to any part of the surface at high temperatures with good and stable lubrication properties, to solve more lubrication problems.

Zinc alloy: Zinc alloy is a type of alloy, which can also be called zinc-based alloy. Its main element is the addition of zinc, and some other elements composed of a type of alloy, can make its casting performance is better, with corrosion resistance, high temperature characteristics, and plasticity is very strong, mainly used for bearing housing materials.

Bearing steel: heat treatment to achieve high temperature resistance, generally used for 300 ° within the working conditions.

The above materials can play a more obvious advantage in the high temperature conditions, the load is greater, will not produce jamming, serious deformation, cage fracture and other undesirable phenomena.

 

Plasti-Oil Bearings:

Plasti-Oil technology has been developed specifically to meet the demands of harsh environments and special operating conditions such as high levels of humidity, moisture, dust, contaminants, silt, maintenance difficulties and grease leakage. The developed plastisol oil is a polymer material with saturated lubricant adsorbed inside, and the lubricant is stored in the micropores inside the polymer based on surface tension. The lubricant is stored in the micropores of the polymer based on surface tension. During operation, a small portion of the lubricant moves slowly towards the surface of the material by capillary action, and when operation is stopped, the lubricant is reabsorbed into the polymer and stored.
