Product Description
Aftermarket replacement for Dewalt 390821-01 bearing. Also fits Porter Cable or Black & Decker bearings with the same part number. The bearings have metal shields on both sides to protect them from moisture and dust. Your application may require that only one side of the bearing has a shield while the other side is open. The shield is easily removed with a small screwdriver. We ship the bearings with both sides shielded to protect the bearing from contamination prior to installation.
