Standard Taper Balancing Wheel Adapters
for Small Surface Grinders.*
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER.
FOR 1.250" ID WHEELS.
Sopko balancing rings have milled pockets with 180° arc-length. One end of the arc is permanently stamped with a reference line and arrow to designate direction of rotation. Unlike some balancing rings, Sopko “sandwiches” the milled pockets together inside the mated faces. Grinding grit can’t build up! Rings are lapped flat and ground for a precision fit. A nylon-tipped set screw secures each ring to the adapter hub. All balancing adapters furnished with a 3/32" hex wrench 00938.

CNC grinders have multiple set-ups requiring wheel location repeatability. To hold this constant wheel position, Sopko adapters are ground to a precision BALL LOCATION, which establishes a constant relationship between the adapter taper and wheel face.

We’ll Help You with CNC Grinding!
  • BALL LOCATION for CNC REPEATABILITY.
  • GROUND external threads for SAFETY you can count on.
  • PRECISION internal taper for RELIABLE spindle mounting.
  • CONCENTRIC and SQUARE surfaces for a BETTER WORKPIECE FINISH.
  • BLACK OXIDE finish and completely HEAT TREATED for years of use.
