6204 bearing is deep groove ball bearing,it has single row and two row ball design,6204 bearing can take Radial Load,as well as carry axial load, compared to with other types of ball bearing who has the same size,6204 bearing have lower speed than angular contact ball bearing, but higher capacity,and self-aligning ball bearing have self-aligning function,it can adjust the tilt between the shaft and the bearing,6204 bearing have one inner ring,one outer ring,one cage and steel balls,we can produce many different 6204 bearing according to the specific bearing application just like cages,metarials,quality level,design,branded,the only can not changed is the dimension:
Inner ring :20mm
6204 bearing has many material: carbon steel,chrome steel,stainless steel,ceramic steel design, carbon steel 6204 bearing don't have district precision,speed and capacity,so it will be low cost,so it must be short service life and be change frequently.
chrome steel 6204 bearing have higher quality than carbon steel on dimension,speed,noise,it have ABEC-1,ABEC-3,ABEC-5 quality demand, XRB can supply Z1,Z2,Z3 level 6204 bearing for the customers who needed,normal quality 6204 bearing can be 1800r/min,and Z1 grade can be 2500r/min,at present these 2 kind of 6204 bearing have much quantity to export.
According to different cage design,6204 bearing have brass cage,pressed steel cage,nylon cage design,and the pressed steel cage is the most used in the market.it be without anything after the bearing designation,M mean the brass cage,A suffix or TN9 mean nylon cage.these cage are all available for us.
6204 bearing is unsplit deep groove ball bearing,it have snap groove and snap ring,there are have open 6204 bearing and rubber seals 6204-2RS Bearing,shielded 6204-ZZ bearing,the sealed bearing all filling with lubrication grease,so it is non lubrication before installcation, very suitable bad environment and dust occasions.
Compared with chrome steel, stainless 6204 bearing have distinct advantage on material,process and accuracy of control,it is more strictly than chrome steel bearing,stainless 6204 bearing is SS6204 Bearing or W6204 Bearing,W6204 Bearing is stable in operation, low noise and corrosion-resistant,it have 440,316 and 304 stainless steel 6204 bearing,it is widely used in medical equipment, cryogenic engineering, optics, high-speed machine tools, high-speed motor, printing machinery, food processing machinery.
6204 ceramic bearings have silicon nitride (Si3N4) and zirconium oxide (ZrO2) two materials, it excellent performance than the metal bearings, high temperature, cold, wear-resistant, corrosion-resistant, anti-magnetic insulation, oil-free self-lubricating, high speed and other characteristics, 6204 bearing ceramic bearing rings and rolling all-ceramic materials, zirconia (ZrO2), silicon nitride (Si3N4), silicon carbide (Sic) three. Retainer using Teflon, nylon 66, polyether imide, zirconia, silicon nitride, stainless steel or special aviation aluminum manufacturing, thereby expanding the application of ceramic bearing surface.
XRB （China bearing manufacturer) manufacture chrome steel 6204 bearing ,Normal quality and Higher quality for different market.at present our customers from South East,Euro,USA,India,Russia,South-Africa market.our 6204 bearing production is 900,000pcs per year,6204 bearing,6204-ZZ Bearing and 6204-2RS Bearing are all available
