Measure the required span between your pulleys and add enough for tensioning — typically 5–10% extra. This belt is sold by the meter (1 m ≈ 39.4 in), so round up to the next available length. For example, if you need 1.8 m, select the 2 m option. For closed-loop applications, calculate the total loop circumference and order accordingly, then join with belt clamps.

HTD (High Torque Drive) profiles use a rounded tooth form optimized for high-torque, moderate-speed drives. S-series profiles use a modified curvilinear tooth that generally offers slightly higher load capacity at the same pitch. XL is a trapezoidal profile suited for lighter-duty, precision positioning tasks. In all cases, the profile must match your pulleys exactly — they are not interchangeable.

Load capacity depends on the profile, width, and operating speed. Wider belts (30–40 mm) in the 8M/S8M profile generally handle the highest torque loads. For precise ratings, consult your pulley manufacturer's datasheet or contact us with your application details. As a general rule, wider belts and larger pitch numbers indicate higher torque capacity.

Polyurethane (PU) typically offers better resistance to oils, mild chemicals, and moisture compared to neoprene rubber belts. However, prolonged UV exposure or immersion in harsh solvents may degrade performance over time. For outdoor installations, shielding from direct sunlight is generally recommended to extend service life.

Yes — provided your pulleys match the corresponding profile and pitch (e.g., HTD-5M pulleys for HTD-5M belt). The belt width must be equal to or narrower than your pulley's usable face width. Verify both the pitch designation and the belt width before ordering. If you have the pulley part number, contact us and we can help confirm compatibility.

Yes. Because this is an open-end belt, it can be cut to any length with a sharp utility knife or band saw. This makes it well-suited for custom machine builds, field repairs, and prototyping where standard closed-loop lengths do not fit. Cut cleanly and squarely across the belt width for the best joint when using clamps.

The tensile cord is steel wire running longitudinally through the polyurethane body. Steel wire provides high tensile strength and very low elongation under load, which is important for maintaining positioning accuracy in CNC routers, 3D printer axes, and other precision linear drives. Fiberglass-cord belts are an alternative for applications requiring non-magnetic or corrosion-free properties.

Open-end PU timing belts can generally be joined using metal belt clamps or lacing connectors sized for the specific profile and width. Ultrasonic or thermal welding is also possible with appropriate equipment. For most DIY and light industrial applications, clamp-style connectors are the most practical option.
