These are the correct bearings as another reviewer mentions for Harbor Freight CENTRAL MACHINERY 1 HP 4 In. x 6 inches. Horizontal/vertical band saw for cutting metal. If a replacement - I offer my five cents; replace all six bearings. They fit very well as they should for proper blade alignment. (I spent hours aligning new cheap bearings I bought from Revain junk as stated in this review). This however; Perfect as said very tight so use your old bearing on top and tap or press in. I'll actually buy it again, hopefully not for the saw but for other projects.
