How much do precision bearings cost? What types of bearings are available?

There are precision bearings in different types of bearings. Precision bearings are different from normal bearings in that they have a higher degree of accuracy. Precision bearings are called precision bearings only when they reach the P5 or P4 level of accuracy. Precision bearings are often used in cutting-edge equipment, such as cell phones and medical devices.

They are also commonly used in machine tools, factories, or equipment with high operational requirements. When we purchase precision bearings, we do not hesitate to ask about the situation. Price is a factor many customers focus on, so how much is a precision bearing?

How much does a precision bearing cost?

According to the different needs of use, but also according to different materials, different precision, and different production factories. The price of precision bearings ranges from a few cents to hundreds of dollars. The better the material, the higher the precision, and the more expensive the price.

Some precision bearings even cost thousands of dollars. When choosing precision bearings, you should understand what kind of bearings you need, and weigh the price of the bearing and the cost of the product. Then go to choose the right precision bearings, we have different bearing styles and precision, fully capable of providing you with the quality bearings you need.

What are the factors affecting the price of precision bearings?

1.According to the bearing precision grade.

According to international standards, bearing precision can be divided into P0, P6, P5, P4, P2, and so on. The higher the precision level, the stricter the production and processing of bearings, and the corresponding cost is naturally higher. The price of our P2 grade high-precision angular contact ball bearings is several times more than P6 grade bearings.

2.bearing brand

The same material, the same precision, size of the bearing, as long as the brand is different, the price may also be a difference of a few cents or a few dollars, or even hundreds of thousands of dollars.

Europe and the United States production of precision bearings, because of the material, process, tariffs, exchange rates, and other factors, the price is much more expensive than China’s precision bearings.

So you need to consider these circumstances when purchasing. Under the premise of meeting the operational needs of the equipment, consider the cost of the product, so that their products are more competitive.

3. Materials of bearings

Commonly used materials for precision bearings are stainless steel, bearing steel, ceramics, etc. Stainless steel is also divided into several kinds, ceramics are also divided into zirconia (ZrO2), silicon nitride (Si3N4), and silicon carbide (Sic) three kinds.

Bearing steel is the most common, the use of the most used materials, and the price is relatively cheap. When it comes to the advantages: of ceramic materials, corrosion resistance, high and low temperature resistance, high hardness, wear resistance, good, lighter quality, good self-lubricating ability, more prominent in the speed, high temperature resistance, the price is relatively high.

4.Procurement channels.

Precision bearings can be purchased from manufacturers or agents, generally, Chinese bearings have more price advantage, and the quality is also very good, we welcome you to inquire, no matter how much you want to order.

What are the common precision types of bearings?

We have all types of bearings.

Angular contact ball bearings, rolling body is spherical, contact angle using 15 ° – 40 ° design, precision level to P5, P4, P2 level, can withstand both radial and axial load, mainly used in CNC machine tool spindle, precision transmission device, high-speed electric spindle.

Deep groove ball bearings, the structure is relatively simple, can withstand radial load, a small amount of axial load, common accuracy of P5/P4 level, suitable for use in low and medium-speed precision pumps, machine tools, and miniature robot joints.

Cylindrical roller bearings, roller, and raceway line contact, radial load carrying capacity, accuracy P5, P4, P2, can meet the machine tool spindle, screw support, and other high rigidity equipment needs.

Tapered roller bearings, the roller is tapered, can adjust the preload, and can withstand radial and axial joint load, mainly P4 level, paired use can be high-precision preload, commonly used in precision gearboxes, CNC machine tools feed shaft, and so on.

Mixed ceramic ball bearings, ceramic balls as rolling body, inner and outer rings for bearing steel, high precision, fast speed, suitable for use in high-speed spindle, machine tools, the price is usually more expensive.

These are just to name a few, we have a very large number of types of bearings, almost all.
