Original Makita tension roller arm — part 150837-6 — a direct replacement "tension roller arm complete" for Makita belt sanders.
Fits the tension/roller assembly used on Makita 9910 and 9911 belt sanders (tool uses 76 × 457 mm abrasive belts).
This complete arm replaces the factory-mounted tension arm that holds the roller and mates to the tension roller shaft and shoulder screw (used alongside parts such as tension roller shaft 323776-5, roller 416417-1 and shoulder screw M4 265059-6), so installation restores correct belt tracking and tension.
Compact, correctly indexed to the original parts diagram and supplied as the full arm assembly for a straightforward swap into the sander’s tension mechanism.
