Product Details

440 Series Stainless Steel Balls for Ball Bearing of hardness, stability, corrosion resistance and toughness
 
Product:BSB1011 Bearing Steel roller
 
Easony manufactures balls from a wide variety of 400 Series stainless steels including 410, 416 and 420, 420A, 440A and 440C. 
 
440 Stainless Steel balls are a martenistic-type stainless steel which is used extensively in steel ball bearing applications that require hardness, dimensional stability, corrosion resistance and toughness. 440 Stainless Steel is also used for corrosion-resistant ball and check valves. 440 ball are resistant to corrosion from fresh water, steam, crude oil, gasoline, perspiration, alcohol, blood and food stuffs. Maximum resistance to corrosion and tarnishing is only achieved when 440 is fully hardened and surfaces are polished to a high luster. 440 is also magnetic.

440 Stainless Steel ballsare widly used becaue of their properties as below:
 
High hardnessHRC60-66. This allows chrome steel balls to withstand heavy loads and resist wear and deformation.
Dimentional PrecisionThe material properties enable the chrome steel balls good finishing surface and dimentional precision. Based on high pricision, the noice of the bearings can be very low, even silent.
Low coefficient of frictionChrome steel balls have a low coefficient of friction, which means they can move smoothly and efficiently without generating excessive heat or wear.
Wear ResistanceChrome steel balls maintain their size and shape well over time, even under high loads or in extreme temperatures. This makes them a reliable choice for long-term use in industrial applications.
