Ball Plug Gauges have many advantages over conventional Plug Gauges.

     
  • They are quick and easy to use because they can be inserted at any angle.
  • Due to the very small contact area of the ball, very good "feel" is imparted to the inspector and any roughness is easily detected.
  • They are very effective in detecting any bell mouthing or taper in the hole.
  • Tungsten Carbide Balls offer rugged resistance to impact, wear, temperature, humididty and corrosion.
  • Our standard tolerances are +2.0µm (0.00008") on the "Go" end and -2.0µm (0.00008") on the "No Go" end. However tighter tolerances are available at extra cost.
  • The Spheric-Trafalgar UKAS Laboratory can supply full Certification.
  • Handles can be engraved to your own requirements listing Part Numbers etc.
  • All stems are made from high quality stainless steel.

Construction Details

     
  • For ball sizes 5/32" (4mm) and above, the stem is inserted into a hole spark eroded into the ball and fixed using a specially developed Spheric-Trafalgar adhesive. Below 5/32" (4mm), the balls are brazed to the stems.
