• HOW NSK-AKS STEEL BALLS ARE MANUFACTURED

  Heading
  Material wire is headed into spherical blanks by high speed automatic machines. The accurate blanks obtained in this process have positive effect on the subsequent processes.

  Flashing
  Headed blanks are roughly ground during rotation under high pressure in disk grooves of special cast-iron. Balls are repeatedly fed into the grooves by means of a rotary conveyor.

  Heat Treatment
  Balls are heated, quenched, and tempered in a fully controlled automatic furnace. These procedures give the balls maximum strength and durability.

  Hard Grind and Lapping
  Balls are ground or lapped to final size and finished to the required surface. The dimensional accuracy and surface profiles of the balls are determined by the lapping machine, lapping oils, the material of the lapping disk, lapping pressure and other procedures.

  Cleaning
  Balls are thoroughly cleaned to eliminate stains, dust, and steel powder from the ball surface.

  Visual Inspection
  All balls are 100% inspected with automatic surface-checking machines.

  

• MATERIAL: SUJ2
  NSK-AKS uses only high grade chrome steel of the through hardening type manufactured by the electric furnace process, which is processed by the latest methods of vacuum degassing to insure maximum fatigue life. All sizes and grades are made from the same materials.
