You are buying set of (2) Bearings that fit most motors that are used in hot tubs, this bearing is 17MM ID x 40MM OD. Some of the motors this fits are A.O.Smith/Regal Beloit, Century/Regal Beloit, Franklin Electric, General Electric NOTE: Installing bearings requires special tools and special knowledge therefore this kit is not for someone who has never installed bearings before. Bearing tools not included!! Measure your bearing before ordering since there are many different bearings.
If the center hole of you bearing is 15.9MM you can find those here: 15.9MM Bearing

With the help of the repair videos and the new parts sent, my Dr. Wellness Hot Tub is working like new again. I previously ordered the impeller kit, but luckily, I had not installed it before the bearing issue made itself known. I did add a nitron lined washer to the shaft to prevent water ever getting to the front bearing ever again. I do believe it is a much needed addition and will go a long way to preventing further bearing problems.
