Stainless steel series spherical bearing with seat The bearing and bearing seat are made of high-quality 304 stainless steel, and the solid bearing seat is more solid and stable. After advanced technology production, the appearance of mirror treatment, no black spots and burrs, beautiful, and corrosion resistance, highlighting the noble grade of bearing with seat. 1. Good corrosion resistance. Ordinary stainless steel can not resist corrosion, it is easy to be corroded in an acid and alkali environment, and 304 stainless steel bearings can be used in a strong environment. 2, rust prevention. It never rusts, even in water. 3, no magnetic. Generally, stainless steel bearing magnetism is very large, and it can be sucked up with a magnet, while 304 will not.
