China Precision Conveyor Bearings manufacturers Part No.:stainless steel conveyor bearings What is stainless steel bearing Compared with ordinary bearings, stainless steel bearings not only have obvious advantages in material, but also in terms of process and precision control, they are much stricter than ordinary bearings. In the working process, the stainless steel bearing works stably, with low noise, corrosion resistance and wide application. As the name suggests, the materials used in the bearing are: engineering stainless steel. The bearing inner ring, bearing outer ring, bearing rolling element, cage and sealing ring are all engineering stainless steel materials. stainless steel material). Stainless steel bearing material classification 440C stainless steel bearing1. AISI SUS440C stainless steel (domestic brand: 9Cr18Mo, 9Cr18) is used for bearing ring and rolling element material after vacuum quenching and tempering. The cage and seal ring frame material is AISI304 stainless steel (domestic brand: OCr18Ni9). 2. Compared with ordinary bearing steel, stainless steel bearings have stronger anti-rust and anti-corrosion properties. Choose suitable lubricants, dust caps, etc., and can be used in an environment of -60鈩儈+300鈩? 3. Stainless steel deep groove ball bearings can resist corrosion caused by moisture and a number of other media. This type of single-row deep groove ball bearing is the same as the standard deep groove ball bearing made of carbon chromium (rolling bearing) steel. It has a deep bearing raceway groove, and the fit between the bearing raceway and the ball is extremely high. 4. Due to its high mechanical strength and large load capacity, stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery. 420 stainless steel bearings1. 20 stainless steel, 420 stainless steel is 420 "cutting tool grade" martensitic steel, similar to the earliest stainless steel such as Brinell high chromium steel. 2. 420 has a certain degree of wear resistance and corrosion resistance, high hardness, and its price is the lower category of stainless steel balls, and it is suitable for working environments that generally require stainless steel. 3. 420 stainless steel is suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation tools, household appliances, etc. It is mostly used to manufacture parts that are resistant to atmospheric, water vapor, water and oxidizing acid corrosion. 304 stainless steel bearings1. Compared with higher carbon chromium martensitic stainless steel (such as 440C, 420, etc.), austenitic stainless steel has better corrosion resistance and anti-magnetic properties. 2. The austenitic stainless steel bearing is made of AISI SUS316L (316) or SUS304 material (including inner and outer rings, balls, and cage). 3. Because austenitic stainless steel cannot be hardened as a whole, this bearing is not suitable for larger loads and higher speeds. 316, 316L stainless steel bearings1. Good corrosion resistance. Ordinary stainless steel is not resistant to corrosion and will be corroded in an acid-alkali environment, while 304, 316, 316L stainless steel can be used in a strong environment. 2. 316 will not rust under strong acid and alkali corrosion, and is non-magnetic. Generally, 440 stainless steel bearings have very large magnetic properties. You can use magnets to attract them, while 304, 316, and 316L will not, especially 316 material can be completely non-magnetic. 3. The only difference between 316 and 316L stainless steel bearings is that 316L will not rust and corrode in sea water for a long time. Advantages of stainless steel bearings 1Excellent corrosion resistance: stainless steel bearings are not easy to rust and have strong corrosion resistance. 2Washable: Stainless steel bearings can be washed off without the need to re-lubricate to prevent rust. 3Can operate in liquid: Due to the materials used, we can operate bearings and bearing seats in liquid. 4Depletion rate is slower: AISI 316 stainless steel does not require oil or grease anti-corrosion protection. Therefore, if the speed and load are low, there is no need for lubrication. 5Hygiene: Stainless steel is naturally clean and does not corrode 6High heat resistance: stainless steel bearings are equipped with high temperature polymer cages or cages without a complete complement structure, which can operate in a higher temperature range of 180掳F to 1000掳F. (Requires high temperature grease) Feature of belt conveyor carrying roller idler 1) Strong construction 2) Better balance 3) Low T.I.R 4) Accurate bearing alignment 5) Maximum sealing efficiency 6) Low running resistance 7) Long service with more than 30,000 hours Matters needing attention in the use of stainless steel bearings Stainless steel bearings are very precise parts. As high-performance bearings are used improperly, they will not only fail to achieve the expected performance results, but also easily damage the stainless steel bearings. Everyone must have paid attention to lubrication. In addition to lubrication, the following aspects need to be paid attention to during bearing use. 1. Use and install carefully, do not allow strong punching, directly hit the bearing with a hammer, and do not allow pressure to be transmitted through the rolling elements. 2. Use appropriate and accurate installation tools, try to use special tools, and try to avoid the use of cloth and short fibers. 3. Try to keep the bearing and its surrounding environment clean, even if the invisible smile dust enters the bearing, it will increase the wear, vibration and noise of the bearing. 4. To prevent the bearing from rusting, when picking up the bearing by hand, wash away the sweat from your hands and apply high-quality mineral oil before proceeding. Pay special attention to rust prevention in the rainy season and summer. 5. In the process of installing and installing the heater, it is necessary to understand the temperature range of the high-temperature bearing under different high-temperature bearings. Installation instructions for stainless steel bearings 1. Installation for stainless steel bearings When installing the bearing, be sure to apply equal pressure around the circle of the end face of the ring. In order to install the ring, it is strictly forbidden to use a hammer or other (metal) weight to directly hit the end face of the bearing to avoid damage to the bearing. One side (such as the outer ring) applies pressure, and the other side of the ring (such as the inner ring) is pressed in through the rolling element. This often causes indentation or scratches on the surface of the rolling element. Non-separable bearings are installed on the shaft and the bearing housing at the same time. 440C stainless steel bearings, 420 stainless steel bearings, 304 stainless steel bearings, 316 stainless steel bearings, 316L stainless steel bearings, the basic installation method is the same as the bearing steel of the same model, but the hardness of various stainless steel materials is different. If heating by heater, it needs to be considered The coefficient of thermal expansion of different materials of stainless steel. 2. Fitting of stainless steel bearings Fitting of stainless steel bearings Interference 1) Fix the inner ring and outer ring of the rolling element on the shaft or the bearing box. When it bears the load, the ring and the shaft or the bearing box matching surface will not have relative movement in the radial, axial and rotational directions. This kind of relative movement will cause friction, friction corrosion or friction cracks on the mating surface, and cause damage to the bearing, shaft and bearing housing, and then the friction powder will be mixed into the bearing, causing poor operation, abnormal heating or vibration, etc. 2) Regarding the method of fixing the bearing, it is best to leave an interference on the mating surface of the ring and the shaft or the bearing box for static fit. This fit enables the load of the thin-walled ferrule to be evenly distributed on the circumference. Will not affect the load capacity of the bearing. 3) However, when static fit is used, in addition to the inconvenient installation and disassembly of the bearing, if the bearing adopts a separate bearing, it cannot move axially, so it cannot be used in all occasions.
