Stainless steel bearings are found in large quantities at total bearings. These bearings are particularly made to withstand corrosive environments. Stainless steel bearings are also effective in applications requiring a range of speeds from medium to high, as well as for large loads. The food & beverage sector is the main application area of ​​stainless steel pads is the food and beverage sector, where washing tools are often carried out. In total bearings, we are a housing a large number of stainless steel bearings with various sizes and dimensions.

The Stainless steel pads are produced by using the corrosion resistant material. In addition, they are resistant to chemicals and can withstand high temperatures of up to 300 degrees. Stainless steel pads tend to hold more temperature resistance than chrome steel. As previously discussed that stainless steel bearings are designed for rusty applications but there are limitations too. They cannot resist every type of water. Stainless steel pads are greatly affected if used them with strong acids, alkali, or in sea water. The best stainless steel pads are 440-grade stainless steel, but some environments are considered more corrosive for 440 class stainless steel, for this purpose, there are other alternatives to visit.

For example, 316 class stainless steel bearings or plastic bearings can be utilized instead of it. However, this bearing is not so strong that it is only designed to carry a lower load with a lower speed. If the load and speed must be increased, the best alternative is a ceramic bearing. Apart from the food and beverage industry, stainless steel bearings can be used in the vacuum related applications only if oil is compatible with the right vacuum used. Lubricants are not necessity, at low speed they can work well even without lubricants. In some cases, the dry lubricants can be applied to serve the purposes such as the molybdenum disulfides or the tungsten disulfides.

In the manufacture of the precision ball bearings, the roller ball bearings, and the tapered roller ball bearings the most common material that is used is 52100, chrome steel. The components made from this material include the rings (inner and outer both), balls, and the rollers. Chemically the composition of carbon is higher and that of chromium is just 1.5%. Some controlled heat treatment methods are applied to the product to make it more strengthen and to resist the cracking of the surface. The hardness of the material made from this falls under the criterion ranging from 60-64 on Rockwell Hardness C Scale Rc.

Austenite stainless steel

For the manufacture of raceways Martensite stainless steel which is equivalent to SUS 440C is used. Similarly, for the rolling elements, Martensite stainless steel SUS 440C is also used for manufacturing. For the slinger and retainer SUS 304, the best choice is the Austenite stainless steel. The bearing enclosure is made of Austenite stainless steel casting SUS 13.

AIS316 AUSTENITIC STAINLESS STEEL
AIS316 AUSTENITIC STAINLESS STEEL

This material is the best for the manufacture of marine-grade stainless steel bearings. This allows the significant resistance against the corrosion, acids, alkalis, and salt spray. Moreover, this type of bearing is suitable to be applied in high-temperature areas. The maximum temperature they can bear is nearly 500 degrees Celsius and almost 930 Fahrenheit.

Thick metal studs are installed on the outermost ring of these bearings. This ring helps bearings for easy locations in housing. During the axial movement the thrust load also prevents bearings. In addition, in a large vibration place, bearings can be placed in housing simply and easily. These bearings are also used with the homes made of other materials. They can expand more than a bearing outer ring at a higher temperature. When a bearing is not fleneda, it slides around inside the housing. If utilized with the proper high-temperature lubricants and stainless steel followers, these bearings can survive temperatures of 250° to 300°F. If the temperature increases beyond the reach, the recorded ability of the maximum load bearings starts to decline slowly. In addition, they are also suitable for a rather corrosive environment.

Stainless steel miniature bearings are known as micro bearings which are used in instruments also. They are mostly used in clocks, watches, wind measuring instruments, medical equipment, fishing reels, camcorders, cameras and small drones. They have an outer ring flange. The majority of our miniature stainless steel bearings are available with or without shield stainless steel AISI-304. Only available mini sizes are open. Some large sizes are found to have a contact seal made of rubber or Teflon, or with a little non-contact rubber seal. Usually, an open type miniature bearing is lubricated with oil. Shielded or sealed bearings are usually lubricated with oil and other lubricated materials. However, shielded bearings can also be accompanied by oil instruments for applications involving the low torque. They also come in a completely dry form for low speed applications that require very low rotation resistance. Our miniature stainless steel bearings are also reset with our customer specifications thanks to our special lubrication facilities at home.

What are the benefits of using Steel housings?

For the food business application, the tempered steel house is the most appropriate and ideal decision. This fine bearing is additionally impervious to water and synthetic deterioration as their thermoplastic accomplice, however they enjoy a few benefits. They are actually more enthusiastically to use than thermoplastics, which might be required by the application. Other than that, they have exceptional alluring power standard plastic conventional.

Steel lodging can endure flexures or breaks more than plastic material. This implies steel lodging demonstrated more grounded. Hardened steel houses additionally don’t ingest dampness, which is vital while encountering successive washing. That implies they are protected from expanding and expanded hazard of disappointment required. A few refined thermoplastics, however not all, can forestall dampness retention. Their fixings fall apart every once in a while on the off chance that FailSafe doesn’t exist.

What are the corrosion-resistant bearings?

Their primary and basic areas of applications are include food processing units, chemical processing units, pharmaceutical items production, and some other marine application units. Throughout the world, the most commonly used bearings are the stainless steel bearings that help in resisting corrosion to a maximum degree.

What are the key remunerations of stainless steel bearings?

They help to resist the corrosion problem. Thus they are applied where the moisture content is higher. The ordinary chrome steel bearings can catch rust easily. These components are employed in food and beverage and pharmaceutical processing industries.

Are our stainless steel bearings magnetic in nature?

It is a prevalent misperception that all stainless steel versions are non-magnetic and that the otherwise test will differentiate stainless steel from carbon steel. Actually this is not a truth. Stainless steel bearings made of 440 grades steel are very magnetic. 316 stainless steel bearings are slightly ferromagnetic.

Name the variation between stainless steel and chrome bearings?

But on the benefits side, stainless steel bearings overwhelm their chrome counterparts. Stainless steel bearings are more extremely durable and can endure warmer concentrations. They are also premeditated to work in higher temperatures as well. If proper lubrication is done they can perform normal operations even at 300 degrees. On the contrary, ordinary chrome bearings lose their efficiency at 150 degrees Celsius and 302 Fahrenheit.

Is it possible to use stainless steel bearings without lubricating oil?

Yes, stainless steel pads are designed to work even without any lubrication. That’s why they are known as dry. In the case of chrome steel pads, they need lubrication because they work effectively with oil protective films. This protective oil film blocks corrosion. In the case of stainless steel bearings, this film is not present so that lubrication is also not needed. The only downside is that at no lubrication, the stainless steel ball bearings will work at low speeds only.
