Wheel Adapters for Wickman
OPG and
Sheffield Micro-Form Grinders.
3.500" TPF WITH .56" DIAMETER AT LARGE END OF TAPER.
FOR .750" AND 1.250" ID WHEELS.
Designed for the Wickman OPG Grinder and the Sheffield 121, 122, and 122A Micro-Form Grinder, these adapters feature a one piece hub design to distribute 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. For optimum micro finishes, all surfaces have been ground concentric and square. A precision taper makes spindle mounting reliable, and the heat treated hub and nut assures long-life and safe operation. Spindle uses a 5/16-24LH spindle nut 05335 (not furnished).
