  • tainless steel ball 440 / 440C: Performance: hardness of 56-58 degrees, magnetic, corrosion resistance, high wear resistance and toughness
    Uses: mainly used in bearings, stamping / hydraulic fittings, valves, seals refrigeration equipment, aerospace and high precision mechanical parts, handicrafts, toys.
    Specifications: 0.5mm-100mm
    ApplicationSs: 440C stainless steel balls are usually used for precision and rust resistance are demanding industries: aviation, aerospace, bearings, motors, high-precision instruments, valves, oil.
    Features: microstructure is martensitic steel, high production process requirements, less domestic enterprises can produce stainless steel 440C, 440C are able to produce materials companies often dubbed special stainless steel in the world. Heat treatment process more complicated, easy to crack, and high precision, is a ball the hardest steel ball: HRC -58. Hardness approaching ball bearings, but the former has a stronger anti-rust, corrosion resistance.
    Compare:stronger than the 440stainless steel ball rust, corrosion resistance, hardness enhanced wear resistance increases.

  • FAQ

     a) How to prolong service life of bearings?

    Accurate installation and using,alignment,timely monitor,re lubrication etc.

    b) Reason for bearings failure?

    Usually is incorrect using method,pollution,improper use of lubricant,damage happened
    in installation and handing,also including installation error.according to the traces can
    know the reason why is failure.

    c) How to choose bearings?

    Analyse mechanical device and use conditions.clear the requiremment of
    bearings.select type of bearings,select distribution way of bearings.selet dimensions of
    bearings,select installation method of bearings.

    d) When select bearings specifications,what you need to consider?

    The precision of the bearings(rotating precision,dimensional tolerances)internal
    clearance and preload bearing material and heat treatment.structure of cage and material.
