The bearings of the oil free air compressor are made of that type of grease

The bearings of oil-free air compressors should be sealed grease with sealing, pressure resistance, lubrication and corrosion resistance.

Commonly used models are: Hotolube's fully synthetic high-temperature sealing grease or fluorosilicone grease; L-64 or L250L from Kluber, HG112 grease from Huskey.

Due to the poor low-temperature performance of mineral oil greases, the above synthetic grease types are recommended.

Oil-free air compressors need to use special sealing grease or lubricating grease, there are two types:

1) Fully synthetic sealing grease, very viscous, dedicated to pressure or vacuum equipment, can withstand vacuum, the specific models are: Tiger Head Hotolube fully synthetic sealing grease, Klube's GLK 112 and Bostik's HW21S.

2) Fully synthetic lubricating grease, relatively viscous, can be used for bearing or piston seal lubrication, withstand vacuum degree about, the specific models are: tiger head Hotolube fully synthetic lubricating grease, Klube's GTE703 and FUSD HS202.

For specific use, you can ask the manufacturer of lubricating oil.

In general, lubricants are selected based on their properties.

The choice of lubricating oil also needs to be regular, otherwise you will buy a fake.

Hello dear, so glad to answer for you!! Self-lubricating bearings and oil-free bearings are two different bearing types that have some differences in lubrication methods and performance. 1.

Lubrication method: The self-lubricating bearing contains lubricant inside, which releases the lubricant through frictional heat to form a lubricating film and reduce friction and wear. Oil-free bearings use a dry-slip material, such as polytetrafluoroethylene (PTFE), to form a low-friction coating on the bearing surface to achieve dry friction and lubrication.

2.Maintenance: Self-lubricating bearings have long maintenance intervals and reduce maintenance to a certain extent due to the continuous release of internal lubricant.

Oil-free bearings, on the other hand, do not require external lubrication and do not need to be supplemented with oil or grease, saving maintenance time and costs. 3.Applicable conditions:

Self-lubricating bearings are suitable for high temperature, high speed, high humidity, low load and other working conditions, and can provide stable lubrication effect. Oil-free bearings are widely used in low-speed, high-load, impact load, messy high temperature and other environments, with high load capacity and wear resistance. When choosing to use self-lubricating bearings or oil-free bearings, it is necessary to comprehensively consider factors such as working conditions, bearing requirements, maintenance costs, etc., and make a choice according to the actual situation.

Summary. Dear, we are glad to answer for you, self-lubricating bearings and oil-free bearings are two different types of bearings, and there are the following differences between them:1

Lubrication method: By adding special lubricating materials, self-lubricating bearings automatically release lubricant during operation to form their own lubricating film, thereby reducing friction and wear. Oil-free bearings, on the other hand, do not require the addition of lubricating materials and are usually lubricated using dry film lubrication or by means of an embedded solid lubricating material.

2.Coefficient of friction: The lubricating film of self-lubricating bearings can effectively reduce friction and wear, and has a low coefficient of friction.

Oil-free bearings, on the other hand, have a relatively high coefficient of friction due to the use of dry film lubricated or solid lubricating materials. 3.Conditions of use:

Self-lubricating bearings are suitable for various working conditions, especially in harsh environments such as high temperature, high speed and heavy load. Oil-free bearings are suitable for special working conditions, such as vacuum, high speed, high temperature and non-lubrication conditions. 4.

Maintenance: Self-lubricating bearings often require regular lubricant additions or changes to keep them functioning properly. Oil-free bearings, on the other hand, are easier to maintain because they do not require lubricants, reducing the maintenance workload of the lubrication system.

Dear, we are glad to answer for you, self-lubricating bearings and oil-free bearings are two different types of bearings, and there are the following differences between them:1Lubrication:

By adding a special lubricating slag key material, the self-lubricating bearing automatically releases the lubricant during operation to form its own lubricating film, thereby reducing friction and wear. Oil-free bearings, on the other hand, do not require the addition of lubricating materials and are usually lubricated using dry film lubrication or by means of an embedded solid lubricating material. 2.

Oil-free bearings are suitable for special working conditions, such as vacuum, high speed, high temperature and non-lubrication conditions. 4.Maintenance:

Self-lubricating bearings often require regular lubricant additions or changes to keep them functioning properly. However, the oil-free bearing is not as lubricant as the cover, so it is easier to maintain and reduces the maintenance workload of the lubrication system.

To sum up, there are significant differences between self-lubricating bearings and oil-free bearings in terms of lubrication methods, friction systems, use conditions and maintenance. The choice of which type of bearing should be determined according to the specific application requirements and working environment.

Mainly look at the type of air compressor, small air pump general mechanical oil on the line, do not viscosity too high on the line, stand above the use of special air compressor oil, factory continuous operation of high pressure or gas production of large air compressor according to the manual oil number can not be replaced, the model is 32 or 46, there is a mineral oil semi-synthetic oil fully synthetic oil, according to the region and the size of the air compressor selected.

It mainly depends on what brand it is, and there are generally special recommended oils. Well-known brands of oils, No. 32 and No. 46, are more commonly used.

The model number is 32 or 46.

There are also mineral oils, semi-synthetic oils, and fully synthetic oils.

It is selected according to the region and the size of the air compressor.

No coking, good cooling effect is OK.

It's a sleeve made of copper skin, and you can see it when you go to the bearing store.

Oil-free bearing is a new type of bearing that has both the characteristics of metal bearing and the characteristics of oil-free lubrication bearing, and all self-lubricating bearing machinery needs this kind of bearing. As a leading brand of bearings, GGB's oil-free bearings have also become industry benchmarks. GGB high-performance dry friction bearings achieve oil-free or low-oil operation through a low-friction packing in the sliding layer, with a wear-resistant sliding layer and a robust, high-strength construction.

I don't know if it's what we call powder metallurgy oil-impregnated bearings.

1.The so-called powder metallurgy is to use metal or alloy powder as raw material, press it with a mold at a certain temperature and multiply a certain shape, and then sinter and shape it at a high temperature.

2.Powder metallurgy manufactured products may be characterized by porosity. If the finished product is soaked in lubricating oil, the pores of the product contain lubricating oil.

As a plain bearing, the coefficient of thermal expansion of porous materials and lubricating oil is different, so the oil is squeezed into the friction surface from the pores during operation, and the oil is sucked back into the pores with the temperature drop when the operation is stopped. This is the oil-impregnated bearing.

3.Oil-impregnated bearings are generally made of tin bronze powder.

Oil-free bearings are self-lubricating bearings, which can also be self-lubricating in an oil-free environment, and we mainly produce and develop oil-free bearings.

Non-lubricated bearings are made of self-lubricating materials, or pre-provided with anti-friction materials to the base material or its friction surface, which can operate in a dry friction state without adding lubricant or for a long time without adding lubricants, also known as dry friction bearings.

Bearings made of self-lubricating materials or materials containing solid lubricants are called non-lubricated bearings, and they operate in a dry friction state. It is used as a material for non-lubricated bearings. The vast majority are plastic.

When using this kind of bearing, the surface roughness of the journal should be RA, and should have a high hardness, and the bearing should have a large clearance, because after the plastic absorbs moisture and stresses relaxation, the size will change, and the linear expansion coefficient is larger than that of steel. The common width-diameter ratio of bearings is that the thickness of the bearing should be as thin as possible to facilitate heat dissipation.

Oil-free lubricated bearings can also be referred to as self-lubricating bearings.

Self-lubricating bearings are divided into composite self-lubricating bearings, solid inlaid self-lubricating bearings, bimetallic material self-lubricating bearings, and special material self-lubricating bearings. 00

One of the major types of solid inlaid self-lubricating bearings is a kind of novel lubricated bearing with the characteristics of both metal bearing and oil-free lubrication bearing, which is subjected to load by metal matrix, and specially formulated solid lubricating material plays a lubricating role. It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, strong self-lubrication ability, etc., especially suitable for heavy load, low speed, reciprocating or swinging and other occasions that are difficult to lubricate and form oil film, and are not afraid of water flushing and other acid erosion and scouring. At present, the products have been widely used in metallurgical continuous casting machines, rolling equipment, mining machinery, molds, lifting machinery, textile machinery, wind power generation, ships, steam turbines, water turbines, injection molding machines and equipment production lines.

The wear resistance is twice that of ordinary bushings.

Oil-free lubrication means self-lubrication without lubricating oil. Non-lubrication is also called dry friction.

Bearing refers to the part (part) used to determine the relative motion position of the shaft and other parts, and plays the role of support or guidance.

Got it ...

The so-called oil-free bearing (OOB-10) refers to the ability to achieve self-lubrication under the condition of no lubricating oil, and no lubrication is also called dry friction.

It's simple: no need for relubricated bearings.

Bearings that are not lubricated with oil are lubricated with pressurized air.
