Genuine 8 Tension Roller Complete 9403 Belt Sander

The Makita 150978-8 Tension Roller Complete is a genuine OEM spare part designed to restore correct belt tension and stable tracking on the Makita 9403 belt sander. A worn or damaged tension roller is one of the most common causes of belt slip, wandering, and uneven sanding performance. This complete roller assembly replaces the faulty component directly, restoring smooth, consistent operation without any modification to the machine. Built to Makita's original specifications, the metal construction is engineered for reliable service under regular workshop and site use. The true-running roller surface reduces vibration and belt slip, supporting even belt wear and helping to extend the working life of both the sanding belt and the machine itself. Designed specifically for the Makita 9403 and MT940 belt sanders, this is a direct-fit replacement that keeps downtime to a minimum. It is equally suited to routine preventative maintenance or restoring a sander that has seen heavy professional use.
