Do you know what stainless steel bearings are ? What is the difference between stainless steel bearings and ordinary bearings? Compared with ordinary bearings, stainless steel bearings not only have obvious advantages in terms of material quality, but also have stricter control than precision bearings in terms of process and precision. In the course of work, stainless steel bearings are stable, low noise, corrosion resistant and widely used. In order to help friends who are interested in this area, I will explain to you below what stainless steel bearings are. What is the difference between stainless steel bearings and ordinary bearings? For consumers' reference!
Stainless steel bearing
Stainless steel bearings can organize mass production and achieve high strength and high precision. Can be used in a variety of products that are easy to rust, corrosion, and widely used.
High-performance stainless steel bearings also provide high-precision and wear-resistance comparable to high-carbon chrome steels on the basis of clean and corrosion resistance, with an accuracy of more than ISO standard ABEC-1. Vibration level Z1 and above.
Stainless steel bearing product features
The bearing rings and rolling elements are made of AISI SUS440C stainless steel (domestic number: 9Cr18Mo, 9Cr18) which has been vacuum quenched and tempered. The cage and seal ring frame material is AISI304 stainless steel (domestic number: 1Cr18). Compared with common bearing steels, stainless steel bearings have stronger rust and corrosion resistance. Selecting suitable lubricants, dust covers, etc., can be used in an environment of -60°C~+300°C. Stainless steel deep groove ball bearings are equipped with dust caps. [2] Some also have contact seals. Bearings with dust caps or seals on both sides are lubricated for life and do not require maintenance. Stainless steel bearings are also widely used in food processing, medical devices, and pharmaceutical machinery because of their high mechanical strength and large load capacity.
Stainless steel bearing advantages
1, excellent corrosion resistance: stainless steel bearing is not easy to rust, has a strong corrosion resistance.
2, can be washed: stainless steel bearings can be washed down without having to re-lubricated to prevent the rust of punishment.
3, can run in the liquid: due to the material used, we can run in the liquid bearing and bearing seat.
4. Slow exhaustion: AISI 316 stainless steel does not require oil or grease for corrosion protection. Therefore, if the speed and load are low, no lubrication is required.
5, health: stainless steel is naturally clean and does not corrode.
6. High heat resistance: Stainless steel bearings are equipped with high temperature polymer cages or cages that are not in a complete complement structure and can operate at higher temperatures ranging from 180°F to 1000°F. (Requires high temperature grease)

Stainless steel bearing failure causes
Stainless steel bearing fracture failure is mainly due to defects and overload two major factors. When the applied load exceeds the limit of the material strength, the fracture of the part is called an overload fracture. The main cause of overload is the host's sudden failure or improper installation. Micro-cracks, shrinkage holes, bubbles, large foreign debris, overheated structures, and local burns of bearing parts can also cause fractures at the defects at the time of impact overload or severe vibration, which is called defect fracture. It should be pointed out that in the manufacturing process, during the re-inspection of raw materials, quality control of forging and heat treatment, and control of the processing process, the bearing can correctly analyze whether the above-mentioned defects exist, and it is necessary to strengthen the control in the future. However, in general, most stainless steel bearing failures that usually occur are overload failures.
Editor's summary: The above is what a stainless steel bearing, stainless steel bearing compared with the ordinary bearing what the difference is related to the introduction, hoping to help meet the needs of friends!

The pH ORP analyzer includes a pH controller also called a pH transmitter and a pH sensor or ORP sensor. pH is also called acid-base value, which directly reflects the concentration of hydrogen ions in water. When the pH is greater than 7, the water is alkaline, when the pH is equal to 7, the water is neutral, and when the pH is less than 7, the water is acidic. There are many factors that affect the pH value of water, and temperature is one of them. Therefore, when measuring the pH value, it is necessary to compensate for the temperature. The pH ORP analyzer developed and produced by Daruifuno is a reliable product. We provide analog and digital two types pH ORP analyzers.
- The pH controller is compact in shape, with small size or large size, which can meet various installation needs of customers, and we also provide matching installation accessories.
- Since temperature has an impact on pH measurement, for more accurate measurement, the pH meter has temperature monitoring and automatic temperature compensation functions, which can be manually or automatically compensated. The matching pH sensor has a built-in temperature unit, NTC10K, PT1000, etc.
- The pH orp analyzer has 2 SPST relays with high and low settings, which can control dosing, cleaning and temperature.
- 2-way 0/4-20mA circuit output, which can output pH or ORP value and temperature value.
- The online pH meter also has an RS485 interface and supports the Modbus communication protocol.
- In addition, the pH ORP analyzer also has functions such as password setting and test maintenance.
- The enclosure protection grade is IP66, and it can be used continuously outdoors.
- The large-sized pH meter also has time and history functions.
The pH control process widely exists in petroleum, chemical industry, pharmaceutical, papermaking, wastewater treatment and water supply treatment. In industrial production, the pH value must be strictly controlled within a specific range, otherwise it may cause product quality degradation, waste of raw materials, production failure, and even environmental pollution. Therefore, the pH value can be controlled within a certain range by using a pH orp analyzer.
