CBN Self Aligning Spherical Washer Set

Some problem grinders will create a little side to side movement in the wheel due to seating problems against the the shaft shoulder near the motor housing, or unequal pressure from the shaft nut. This movement will interfere with the accuracy of sharpening when using the wheels. We have found If you experience this problem these self-aligning Spherical Washers will do the trick. Washers are NOT needed for 6" or 10" wheels.

 The Spherical Washers act as a ball and socket to compensate for slight misalignment and to eliminate undue stress from the shaft nut. The hole size on this ball and socket set is slightly larger for efficient equalizing action. Please see photos for  proper mounting. Sold as a set only with the ball and socket set and flat washer. Made in the USA. This three piece set is for one 8" CBN Wheel so if buying two 8" CBN wheels you will need two of these.
