3. We should choose bearing models according to bearing material
When we purchase bearing, material is one of the most concern questions. The selection of bearing material should be in accordance with working environments and the size of load. Then I'll introduce several kinds of common materials. Stainless steel bearing has advantages of acid resistance and water-proof. Lily has 440, 316 and 304 stainless steel materials. As a standard structure stainless steel bearing, 440 stainless steel material is widely used. It not only has the advantages of low price and high rigidity, but also can undertake high load and high rotation speed. 316 stainless steel bearing has advantages of rust resistance and corrosion resistance. The corrosion resistance performance of 304 stainless steel bearing is better than 440 stainless steel bearing, but its price is lower than 316. Another high-technology product is full ceramic bearing, which is essential in bearing industry. Full ceramic bearing has cold resistance, high temperature resistance, abrasion resistance, corrosion resistance, resistant to magnetoelectricity insulation, high rotation speed and self-lubrication without oil characteristics. Under extreme harsh environment, ceramic bearing occupies important position.
There is other knowledge about choosing bearing. We may encounter lots of special circumstances. The container material and clearance size can affect bearing's use. So it is our common goals and is also our responsibility to accumulate more knowledge to choose the most appropriate and most standard bearing.
