Standard Taper Flanged Wheel Adapters.
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER. FOR 1.250" ID WHEELS.  DESIGNED FOR THIN CUT-OFF WHEELS AND DIAMOND WHEELS.


Sopko flanged adapters are machined from alloy steel. The resulting one piece hub design distributes mounting pressure away from the bore, the weakest part of the grinding wheel. The inherent rigidity of one piece design, and the precision ground flanges provide identical radial load bearing surfaces for positive wheel lock and better spindle driving torque to the abrasive wheel. All surfaces are ground concentric and square for optimum surface finishes. Completely heat treated, Sopko flanged adapters are safe to use and maintain their rigidity.

3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER.* FOR 2.000" AND 3.000" ID WHEELS.


Now you can extend the useful working life of 2.000" and 3.000" ID grinding wheels. There is no need to waste money by throwing worn wheels away. Extend wheel life, use Sopko 4-1/2" flanged diameter wheel adapters! Machined from forged alloy steel, the one-piece hub design distributes mounting pressure away from the bore, the weakest part of the grinding wheel. The inherent rigidity of one piece design and the precision ground flanges provide identical radial load bearing surfaces for positive wheel lock and better spindle driving torque to the abrasive wheel. All surfaces are ground concentric and square for optimum surface finishes. Completely heat treated, Sopko flanged adapters are safe to use and maintain their rigidity.

Standard Taper Flanged Balancing
Wheel Adapters For Small Surface Grinders.*
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER.
FOR 1.250", 2.000", AND 3.000" ID WHEELS.
With operator safety in mind, Sopko offers a selection of balancing adapters having a variety of diameters for larger OD wheels. At Sopko the focus is always on operator safety; that’s why we designed and made these balancing adapters with precision internal tapers and thread ground OD threads. And that’s not all, we heat treat component parts for strength and grind all surfaces square and concentric for truly flat bearing surfaces. For safety, increased productivity, low-micro finishes, and reduced wheel wear, insist on Sopko large OD balancing adapters.

Standard Taper Reversible Wheel Adapters.
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER.  DESIGNED FOR 1.250" ID DIAMOND, CBN, AND VITRIFIED WHEELS.


THERE IS A DIFFERENCE WITH SOPKO REVERSIBLE ADAPTERS!

  • Formed wheels are used either way without redressing.

  • Can be REVERSED without DISMOUNTING the wheel for prolonged square corner life of diamond wheels.

  • Sopko reversible wheel adapters make it possible to use the same dressed angle for
    BOTH RIGHT AND LEFT GROUND TOOL BITS.

  • EASY TO USE-Just remove the adapter from the spindle nose and REMOUNT in the reverse direction.

  • SAFE TO USE-Sopko reversible wheel adapters are manufactured with a double-taper and are securely locked against loosening by the wheel rotation.

  • Manufactured from quality steel to withstand the rigors of daily use, then HARDENED and GROUND.
     

For use on all spindles having a 3.000" TPF with 1.00" diameter at large end of taper.  Including: Boyar-Schultz, Bridgeport, Brown & Sharpe, DoAll, Excello, Foote Burt-Hammond, Harig, Norton, Parker Majestic, Pope, Reid, Sanford, Setco, Taft Pierce, and Whitnon.

A precision ground double-taper and removable bushing make wheel mounting in opposite directions safe and reliable. Grinding wheel edges wear during use, but obtaining a new sharp edge is as easy as reversing the adapter on the spindle. LH thread is standard.

Standard Taper Electroless Nickel Plated Adapters.
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER.
FOR 1.250" AND 3.000" ID WHEELS.
If corrosive coolants pose special problems for you, choose Sopko ELECTROLESS NICKEL PLATED wheel adapters to reduce the high cost of replacement. Widely used in ELECTROLYTIC GRINDING machine applications and the RUBBER ROLL GRINDING industry, Electroless Nickel plating deposits a uniformly dense coating of nickel-phosphorus alloy onto the adapter surface.

Sopko Electroless Nickel coatings offer you...
  • A HARD PROTECTIVE SHELL providing outstanding protection against wear and abrasion.
  • AN ECONOMICAL ALTERNATIVE to stainless steel or hard chrome finishes.
  • UNCOMMON CORROSION RESISTANCE to today’s harsh coolant environments.

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.
