Self-Aligning Spherical Washer Sets - for two CBN Wheels
3-piece set (for two CBN Wheels)
We suggest that at the very least you should use a good quality flat washer on each side you your 8" CBN wheel (washers are NOT needed for 6" or 10" wheels). Some problem grinders will create a little side to side vibration in the wheel due to seating problems against the the shaft shoulder near the motor housing, or unequal pressure from the shaft nut. This vibration will interfere with the accuracy of sharpening when using the radius edge of the wheels. We have found If you experience this problem these self-aligning Spherical Washers used in conjunction with the 1010 cold rolled, case hardened, flat washers on the inside of the shaft will do the trick of eliminating any vibration at all.
The Spherical Washers act as a ball and socket to compensate for slight misalignment and will 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 6-piece set is for two 8" CBN Wheels. If you will want to purchase the Spherical Washer Set for one CBN Wheel click here.
