General specifications

The below specifications include an important section on the material specifications as these significantly impact far more the precision in the game than the dimensional aspects.  
Far more important are indeed the material and ball characteristics such as balance, rebound, elasticity, true roll which are essential for the player to control direction, speed and spin.     Learn more

1.    Material specifications 


Resin characteristics 

  • Resin type : genuine Aramith resin
  • Aramith resin : 100% HD (high-density) phenolic resin
  • Density : from 1.69 up to 1.87 depending on Aramith resin type 
  • Density tolerance : +/- 0.015
  • Density dispersion : evenly dispersed throughout ball and parts 
  • Hardness : > 73 HRH (Super Aramith PRO : >80 HRH)
  • Hardness variation : no variation (constant over all ball parts and surface)
  • Duramith™ technology : included in the high end sets     > Learn more
     

Surface characteristics

  • Surface : vitrified surface
  • Vitrification technology : Vitrotech™ by Aramith
  • Surface rugosity :  average Ra = 0.03 microns
  • Surface finish : high gloss polish


Dynamical characteristics       Learn more

  • Rebound : constant within the set
  • Anti-Kick™ properties : highly anti-static to minimize kicks, buttages & skids
  • Balance (density dispersion) : constant throughout the ball sections
  • Surface elasticity : constant over ball 


Durability

  • Impact resistance : over 4.000.000 hits 
  • Burn spot resistance : resists to 250°C break shot instant friction temperatures
  • Cloth wear : minimal, as Aramith keeps its smooth surface and avoids white marks
  • Lifetime : up to 5x longer (more with Duramith™ Technology)


2.    Dimensional specifications

  • Billiard ball diameter range : from 1” up to 2-3/4”
  • Tolerance standard : better than Precision Plastic Ball GRADE III specification limits  
  • Most common diameter (") :
    • Nominal : 2-1/4
    • Diameter tolerance : max +/- 0,003
    • Sphericity / roundness : max 0,002 (high end grade : max 0,0012)


Note : Some specifications are resin type and diameter specific.
