The main reasons for the formation of rust are as follows:
1. Some companies do not strictly carry out anti-rust treatment on the bearing parts and the mounted bearing products during the process of producing the bearing in accordance with the requirements of removing the anti-rusting regulations and the oil-sealing anti-rust packaging. For example, the ferrule is turned over during the turnaround process. The time is too long; the outer circle touches corrosive liquid or gas.
2. The quality of anti-rust lubricants and fire-fighting products used by some companies in production is not up to the requirements of process technology rules.
3. Because the price of bearing steel drops and then falls; then the raw material of bearing steel gradually declines. For example, the content of non-metallic impurities in steel is high (the increase of sulfur content in steel reduces the corrosion resistance of the data itself); the deviation of metallographic arrangement The bearing steel used in the production company is more complicated; the amount of steel raw material is even more.
4, some companies have poor environmental conditions; high levels of harmful substances in the air; turnover places too. Yanyue apricots У 佬獯 佬獯. Plus the weather is hot; production workers against the anti-rust procedures and other appearances are also lacking.
5, some companies' anti-rust paper, nylon paper (bag) and plastic cylinder and other bearing packaging materials do not meet the requirements of rolling bearing oil seal anti-rust packaging is also one of the elements of rust formation.
6. In some companies, the turning allowance and the grinding allowance of the bearing ring are partial. The mining system is difficult (9) smoke and sputum.

Double-Convex Cylinder Lens

A double-convex lens is compose of two convex surfaces, has a positive focal length. Normally Bi-Convex lenses are most suitable where the object and image are on opposite sides of the lens, and are popular for many imaging applications.

Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens. Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.

We supply kinds of plano-convex Cylindrical Lens,plano-concave cylindrical lens,bi-convex cylindrical lens,bi-concave cylindrical lens,meniscus cylindrical lens,Rod cylindrical lenses,special cylindrical lens etc.Every sizes,materials cylindrical lenses are available according to your detailed parameters.
