Standard Taper Short I.D. Wheel Extensions.*
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER. FOR A SMALL RADIUS OR THAT ONE SMALL SLOT. SAVE THE EXPENSE AND SET-UP TIME OF A HIGH SPEED ATTACHMENT.

All SHORT IDWEs come with a floating nut spacer 00662 (FN-1), two flanges, and a wheel end-nut. The hex spindle nut must be selected separately to suit your machine. Most grinders use 1/2-13LH or 1/2-13RH threads. A 1-1/4" wrench flat on the body makes installation and removal easy.

CHECK THESE FEATURES!

ALL DIAMETERS GROUND for concentricity.
PRECISION INTERNAL TAPER for proper spindle mating.
ALL COMPONENT PARTS HEAT TREATED for strength and long life.
THREAD GROUND EXTERNAL THREADS for maximum concentricity and squareness.
SPECIALS can be made to your requirements. Please specify wheel OD, width, and ID.

Standard Taper Long I.D. Wheel Extensions.* 3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER. FOR A SMALL RADIUS OR THAT ONE SMALL SLOT. SAVE BOTH THE EXPENSE AND SET-UP TIME OF A HIGH SPEED ATTACHMENT.

All LONG IDWEs come with a floating nut spacer 00662 (FN-1), two flanges, and a wheel end-nut. The hex spindle nut must be selected separately to suit your machine. Most grinders use 1/2-13LH or 1/2-13RH threads. A 13/16” wrench flat on the step makes installation and removal easy. See page 76 for available hex spindle nut sizes. Extends grinding wheels 13/16" further from spindle nose than the short series ID wheel extensions shown on page 16.

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).
