Original Makita 225084-9 — Synchro Belt 6-330
Keep your Makita belt sander running like new with the genuine Makita 225084-9 synchronous drive belt (listed as “SYNCHRO BELT 6-330”).
Key details:
- Designation: 6-330 — 6 mm belt width with a 330 mm pitch/length appropriate for Makita’s 6×330 synchronous/timing belt specification.
- Function: replacement drive/timing belt for the sander’s pulley train — engineered to match the tooth profile and flexibility used on Makita’s belt-sander assemblies so it seats cleanly and maintains correct tracking.
