Original DeWalt bottom bearing — part number 490330-00. This small, service-replacement bearing fits into the lower blade/shaft area to support the drive roller and shaft assembly in several DeWalt jigsaw models, making it the correct part if your tool has play, grinding noise, or a worn support at the blade drive.

Compatible examples (covers many variants and types): DW333, DW341K, DW343K, DCS331 (20V jigsaw), DC308K and DC330. The part is supplied as the original DeWalt bearing (sold individually) and is listed on the official parts diagrams for those models.

Designed for straightforward replacement, this genuine DeWalt bearing installs into the bearing carrier near the shaft/drive roller and restores the correct running alignment of the blade drive — an economical repair to stop wobble or rubbing and return smooth jigsaw operation.
