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.

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.
