Description
The Mitsuboshi T5 polyurethane timing belt is built from a thermoplastic PU compound that provides high abrasion resistance and dimensional stability. Inside the belt, steel cords (or aramid cords in some variants) act as the tension members to maintain low stretch and stable synchronous accuracy. The tooth surface often incorporates a fine nylon-facing layer to reduce friction, improve engagement, and slow down wear during repeated meshing with pulleys.
Key Features
The PU compound gives the belt excellent resistance to wear, mechanical fatigue, and many industrial chemicals, allowing it to maintain clean performance with minimal particle generation. Its trapezoidal T5 tooth profile ensures predictable tooth engagement and accurate synchronization in light- to medium-duty applications. The belt operates reliably across a broad industrial temperature range and supports relatively high running speeds when paired with correctly sized pulleys. Because PU is dimensionally stable, it provides consistent tension behavior and long-term reliability without lubrication.
Applications
This belt is ideal for precise, clean, and compact drive systems such as printers, small conveyors, packaging units, linear-motion devices, and equipment requiring minimal dust generation. When selecting pulleys, it is important to follow recommended minimum diameters to avoid cord fatigue. Proper tensioning and alignment will further improve belt life and ensure accurate timing. The belt should be kept away from extreme chemical environments and regularly checked for surface wear, especially around the tooth area, to maintain stable performance over long operating periods.
