Talk About The Assembly Process Requirements Of 304 Stainless Steel Bearing

304 stainless steel bearings are a kind of precision and easily damaged mechanical parts, in some use environments, bearings will be protected by bearing box mechanical seal or other forms of seal. The use of these sealing parts occupies a lot of volume space, and has some influence on the design of the use of products. So people gradually move the sealing device to the bearing, and constantly improve and optimize. Nowadays, different bearings with dust cover and sealing ring have been popularized. Bearings with sealing structure are still increasing, and a lot of materials have been added. Today, I mainly talk about the assembly requirements of 304 stainless steel bearings.

Relatively mature and widely used stainless steel bearing with sealing device, is the axle and wheel bearing used in railway half cars, cars and other transportation vehicles. The sealing device structure of these bearings is diversified and has its own advantages for different use occasions. In the assembly of bearings, in addition to the grease injection amount requirements, there are also strict regulations on the requirements of sealed packaging. In general, the seal of this kind of bearing has rubber seals with steel skeleton, and the inner and outer seals, the outer seals and the outer causes, the inner seals and the auxiliary parts of the inner group or the inner ring. And between the inner and outer sealing to achieve the corresponding position relationship, in order to achieve the overall role of the seal, which usually requires the service cycle, maintenance free. These requirements, in addition to the requirements of the relevant parts should be qualified, good assembly quality is also one of the keys to ensure the stability of the sealing device.

304 stainless steel bearing sealing device is also widely used in other different occasions, such as sealing rolling mill stainless steel bearings, is in double, four column bearing on both sides of the sealing device, these sealing devices are used separately, with stainless steel bearings together with compression positioning, can be replaced.
