Cincinnati Taper Flanged and Cup
Wheel Extension Adapters.
4.500" TPF WITH .87" DIAMETER AT LARGE END OF TAPER. FOR 1.250" ID WHEELS. USED ON ALL CINCINNATI NO. 1 AND NO. 2 SPINDLES, COVEL, AND GALLMEYER & LIVINGSTON CUTTER GRINDERS; OR ANY SPINDLES WITH .87" DIAMETER AT LARGE END OF TAPER AND 4.500" TPF.

Sopko flanged adapters are machined from forged alloy steel. The resulting one-piece hub design distributes mounting pressures away from the bore, the weakest part of the grinding wheel. The inherent rigidity of one-piece design and the precision ground flange provides 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.

*Spindle mounting bolt 14362 and retaining ring 04269 included.

Sopko cup wheel adapters are made with a THIN-WALL FRONT FLANGE design to give maximum usage of cup wheel depth. Fully HEAT TREATED, and made from SOLID BAR STOCK, Sopko cup wheel extension adapters are RIGID to provide positive lock. A hardened nut locks the wheel from the back of the adapter. Because of this nut configuration, RH threads are used for CW spindle rotation and LH threads are used for CCW rotation; providing a safe locking system that WILL NOT LOOSEN during spindle rotation.

Cincinnati Taper Reversible Wheel Adapters.
4.500" TPF WITH .87" 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, then HARDENED AND GROUND to withstand the rigors of daily use.

CINCINNATI TAPER "OLD STYLE" REVERSIBLE WHEEL ADAPTER.
A precision ground double-taper makes 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. Designed for the older Cincinnati flat belt center drive spindles, the adapter comes complete with a 1/2-13LH 06074 and a 1/2-13RH 06073 slotted spindle nut.
