Small Deep Groove Ball Bearings 603 Series
Material：304 Stainless Steel / 440 Stainless Steel / Bearing Steel / Normal Stainless Steel
Bearing Model: S603Z S604Z S605Z S606Z S607Z S608Z S609Z
Features:
Bearing steel generally has a high carbon content to enhance wear resistance, while stainless steel generally has a high CR content of more than 12%, mainly to take advantage of its corrosion resistance.
In the working process stainless steel bearings work stable, have low noise, and corrosion resistance, widely used. Stainless steel bearings compared with ordinary bearing steel, have stronger anti-rust, anti-corrosion, choose the right lubricant, dust cover, etc., and can be used in -60 ° C ~ +300 ° C environment. Stainless steel deep groove ball bearings can resist corrosion caused by moisture and several other media.
304 material belongs to the austenitic stainless steel no magnetic mainly contains CR, NI because of the element of nickel, so can be used in strong acid and alkali, corrosive environment but the carbon content of the bottom hardness compared to 440 material soft,
304 stainless steel hardness:
<187HB<90HB-B<200HV overall load-bearing wear resistance and bearing processing process is not as good as ordinary bearing steel and 440 material.
440 material belongs to the martensitic type, stainless steel material contains magnetic, containing 1.0% carbon, the chromium content of 16%-18% resistance to water rust, but corrosion resistance, but acid-alkaline material is not 304 good.
The hardness of 440 material: annealed <369HB, quenched grey fire ≥633HV is the hardest of all stainless steel.
Good rust resistance, wear resistance and high-temperature resistance.
