When your CNC router, conveyor line, or automation axis demands a belt that holds position without creep, a standard rubber belt often falls short. Engineers and makers who need low-stretch, cut-to-length flexibility rely on open-ended polyurethane timing belts with a steel wire tension cord — and that's exactly what this T10 & AT10 open timing belt delivers.
Each meter of belt is manufactured from white polyurethane with an embedded steel wire reinforcement core. Available in two tooth profiles — T10 (standard trapezoidal) and AT10 (modified high-torque profile) — and six widths: 20mm (≈0.79"), 25mm (≈0.98"), 30mm (≈1.18"), 35mm (≈1.38"), 40mm (≈1.57"), and 50mm (≈1.97"). Order in 1m, 3m, 5m, or 10m cuts and trim to your exact run length on-site.
Typical use cases include CNC router X/Y axes where positional accuracy depends on minimal belt stretch, industrial conveyor systems that move parts between workstations, and large-format 3D printer gantries that outgrow narrow GT2 belts. The open-ended format also suits linear actuators, pick-and-place machines, and any application where a looped belt cannot be installed.

Both T10 and AT10 belts share a 10mm pitch, but AT10 features a modified tooth profile with a larger contact area, which generally provides better load distribution and reduced backlash. AT10 is typically preferred in higher-torque or precision-critical applications, while T10 is widely used in standard linear motion and conveyor setups.
Belt width directly affects load capacity. As a general rule, wider belts handle higher lateral forces and torque. For light-duty CNC or 3D printer axes, 20–25mm widths are typically sufficient. For conveyor systems or heavier automation, 30–50mm widths are generally recommended. When in doubt, size up — a wider belt runs cooler and lasts longer under load.
Yes — these are open-ended (non-looped) belts sold by the meter, so you can cut them to any length with a sharp utility knife or belt cutter. Measure your required run length and add at least 50–100mm (2–4") for clamping or termination hardware. Available in 1m, 3m, 5m, and 10m cuts.
The steel wire tension cord provides high tensile strength with minimal elongation under load. Exact load ratings vary by width — wider belts carry proportionally higher loads. For specific tensile force ratings, please contact us to confirm based on your width and application requirements.
Polyurethane is generally more resistant to oils, mild chemicals, and moisture than rubber belts. However, prolonged UV exposure or immersion in water may affect performance over time. For outdoor applications, shielding from direct sunlight is typically recommended. The steel wire core may be susceptible to corrosion in highly humid or salt-spray environments — contact us if you need a stainless-reinforced option.
T10 belts are compatible with standard T10 pulleys (10mm pitch, trapezoidal tooth profile). AT10 belts require AT10 pulleys — the modified tooth geometry means T10 and AT10 pulleys are not interchangeable. Always match belt profile to pulley profile for proper meshing and to avoid premature wear.
Yes. Open-ended T10 and AT10 polyurethane timing belts are commonly used in CNC routers, laser cutters, and large-format 3D printers where GT2 belts are too narrow or lack the load capacity needed. The steel wire core keeps stretch minimal, which is important for positional accuracy on long axes.
