Stainless steel bearings compared with ordinary bearings, stainless steel bearings not only have obvious advantages in material, but also in process and precision control, which is much stricter than ordinary bearings. In the working process stainless steel bearings work stably, low noise, corrosion resistance, and are widely used.
Characteristics of stainless steel bearings：
Stainless steel bearings have stronger anti-rust and anti-corrosion compared with ordinary bearing steel, and can be used in -60℃~+300℃ environment by choosing suitable lubricant and dust cover, etc. Stainless steel deep groove ball bearings can resist corrosion caused by moisture and several other media. This type of single row deep groove ball bearings with carbon chromium steel manufacturing standard deep groove ball bearings, with a very deep bearing raceway groove, bearing raceway and the ball between the fit is extremely high. Stainless steel bearings are also widely used in food processing, medical equipment, pharmaceutical machinery because of their high mechanical strength and high load capacity
Stainless steel bearing material type：
1.440 stainless steel bearing series.
2.316 stainless steel bearing.
3.304 stainless steel bearings.
Stainless steel bearing advantages：
1, excellent corrosion resistance: excellent corrosion resistance: stainless steel bearings are very good, with excellent corrosion resistance, it is not easy to rust, is a good product.
2、Washable: We all understand that many steel-like items will rust after washing, but stainless steel bearings can be washed, and can be washed without re-lubricating.
3, can run in the liquid: basically the material is to avoid the use of liquid, because the use of liquid for a long time, the basic will happen corrosion, rusting situation. But the stainless steel bearing is able to use in the liquid, because the raw materials used in stainless steel is able to run in the liquid.
4, slow depletion: stainless steel bearings AISI 316 in use does not require the protection of oil or lubricants, so the speed and load is low, is no need to lubricate.
5, hygiene: because of his good corrosion resistance, so stainless steel has always been able to maintain a very clean state
6, high heat resistance: stainless steel bearings equipped with high temperature polymer cage or no cage in a complete complementary structure, can run in the higher temperature range of 180 ° F to 1000 ° F. (need to match the high temperature grease)
Disadvantages of stainless steel bearings：
1. High cost: The specific defect of stainless steel bathroom hardware pendant is the high cost and expensive price.
2. Not resistant to corrosion: stainless steel is also not resistant to the corrosion of alkaline media, long-term use or maintenance is not in place will cause a relatively serious damage to stainless steel, so it is still recommended after the purchase of stainless steel bathroom hardware pendant to do a good job of maintenance of stainless steel bathroom hardware pendant.
3. Stainless steel bearing fracture failure
This situation is usually because the bearing itself has defects, or is caused by long-term load. When the applied load exceeds the material strength limit and cause the parts to fracture called load fracture. The load is mainly due to sudden failure of the host, or improper installation of stainless steel bearings.
4. Abnormal temperature rise
If in actual use, the lack of lubrication for the stainless steel bearing, it is very easy to occur the problem of temperature rise, then should immediately replenish the lubricant, and pay attention to check the oil circuit to ensure smooth. If the lubricating oil contains too much dregs, it must be cleaned and filtered immediately to ensure clean lubrication. If it is caused by abnormal installation, it must be adjusted immediately.
Fracture failure causes
Stainless steel bearing fracture failure is mainly due to defects and overload two factors. When the applied load exceeds the material strength limit and cause parts fracture is called overload fracture. Overload causes are mainly sudden failure of the host or improper installation. Bearing parts of micro-cracks, shrinkage, bubbles, large foreign debris, overheating organization and local burns and other defects in the impact overload or severe vibration will also cause fracture at the defect, known as defective fracture. It should be noted that the bearing in the manufacturing process, the raw materials into the factory re-inspection, forging and heat treatment quality control, processing control can be correctly analyzed by the instrument whether the above defects exist, the future must still strengthen the control. But in general, most of the stainless steel bearing fracture failure usually occurs for overload failure
Application areas of stainless steel bearings：
With the level of technology continues to improve, now about the stainless steel bearing products have also achieved the bulk production, and can ensure high strength, high precision, has been widely used in general corrosion of a variety of products. The main application areas of stainless steel bearings and stainless steel bearing applications are medical equipment, cryogenic engineering, optical instruments, high-speed machine tools, high-speed motors, printing machinery and food processing machinery, etc.
