Original DeWalt 490329-00 — a precision top/support bearing used in DeWalt jigsaws to replace a worn bearing that causes blade play, vibration and noise.

The part is a compact steel bearing that locates the reciprocating shaft inside the gear/shaft assembly so the blade runs true and the stroke feels smooth again.

Example fitment (common): DW333, DW331, DC330, DCS331, DC308, DC318, DW341, DW343 and DCS332 — listed in DeWalt parts diagrams and spare-parts listings as part number 490329-00.

Sold as a single, original DeWalt replacement component and ready to drop into the jigsaw’s bearing seat — a straightforward repair when you need genuine DeWalt parts to restore cutting accuracy.

A small, serviceable item among typical power tool parts; install following your model’s exploded diagram to ensure correct orientation and seating.
