Measure the center-to-center distance between your drive and driven pulleys, then use the formula: Perimeter ≈ 2 × center distance + (π × sum of pitch radii). For HTD3M, each tooth pitch is 3mm, so divide your target perimeter by 3 to get the tooth count. For example, a 2700mm belt has 900 teeth. Always verify against your machine's spec sheet or the markings on your existing belt. If you are between sizes, typically size up to avoid over-tensioning.

Divide the mm value by 25.4. Quick reference for this listing's range:

• 2700mm ÷ 25.4 ≈ 106.3"
• 2800mm ÷ 25.4 ≈ 110.2"
• 2900mm ÷ 25.4 ≈ 114.2"
• 2997mm ÷ 25.4 ≈ 118.0"

All perimeters in this listing are available in 3mm increments between 2700mm and 2997mm.

PU belts with a steel wire tension cord generally offer higher tensile strength and lower elongation than rubber belts of the same cross-section. The steel wire core resists stretch under dynamic loads, which is why they are commonly used in CNC and 3D printer drive systems where positional accuracy matters. Exact load ratings depend on the specific wire count and diameter — contact us if you have a defined load requirement.

PU timing belts are generally more resistant to oils, greases, and moderate humidity than standard rubber belts. However, prolonged exposure to standing water, UV radiation, or extreme temperatures (typically outside −20°C to +80°C / −4°F to +176°F) may reduce service life. For outdoor, washdown, or high-UV applications, contact us to confirm suitability before ordering.

Yes. This belt uses the HTD3M tooth profile (3mm pitch, rounded curvilinear tooth form) and is designed to mesh with any standard HTD3M pulley. The 10mm belt width is compatible with pulleys rated for 10mm or wider. Before installing, confirm your pulley's tooth count, bore diameter, and flange clearance to ensure a proper fit.

This perimeter range is typically found in larger-format equipment, including:

• Large-format 3D printers (e.g., CoreXY or bed-slinger designs with long axis travel)
• CNC router gantry drive systems
• Laser engraver and laser cutter motion systems
• Light industrial conveyor and automation equipment

Always cross-reference your machine's belt specification or existing belt markings before purchasing.

The packing quantity option lets you choose 1 belt or a 2-belt pack. The 2-pack is useful when replacing belts on both axes of a machine at the same time, or when you want to keep a spare on hand. Pricing shown is per pack — not per individual belt.
