Self-Aligning Spherical Washer Sets

Some problem grinders will create a little side to side vibration running the wheel due to seating problems against the the shafts shoulder near the motor housing, or unequal pressure from the shaft nut. This movement will interfere with the accuracy of sharpening with the radius edge of the wheels. We have found if you experience this problem, these self-aligning Spherical Washers will do the trick of removing the vibration completely. 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 creating efficient equalizing action. Please see photos for  proper mounting. Sold as a set only with the ball and socket set and flat washer.
