Shaft bearing and race for Bona Pro Sand, Wolf, and Cobra sanders.
This is a needle bearing. Make sure you change the bearing race on the shaft when changing the bearing. The race will wear under size and will create chatter if not replaced. Furthermore, even when this bearing is running smoothly the race can wear under size and create chatter. This is a good item to change along with drum recovery if you are experiencing chatter from your machine.
Electronic start switch used on most modern sanders and buffers. This switch controls the start capacitors. Fits many 220 volt sanders.
Model 2VR50 with cutout voltage of 310. For a cutout voltage of 260, order part number BB206.
