When your CNC router, 3D printer, or conveyor system demands slip-free, repeatable motion, a worn or incorrectly sized drive belt is the last thing you want holding you back. This HTD-5M closed loop synchronous timing belt is built for engineers, makers, and machine builders who need a dependable replacement or upgrade belt without hunting through specialty distributors.
Each belt features a 5mm pitch HTD curvilinear tooth profile and a 20mm working width, with a fiberglass-reinforced neoprene construction for dimensional stability under load. Available in 119 circumference options ranging from 1000mm (≈39.4") to 4260mm (≈167.7"), every variant is listed with its exact tooth count so you can match your pulley system precisely. Sold individually, one belt per order.
Typical use cases include CNC router X/Y axis drives, laser cutter gantry systems, robotic arm joints, and light industrial conveyor lines — anywhere a synchronous HTD-5M timing belt replacement is needed for accurate, low-backlash power transmission.

Measure the center-to-center distance between your two pulleys, then use the standard belt length formula: Belt Length = 2 × C + π × (D1 + D2) / 2. Each variant lists the circumference in mm — for example, 1000mm (≈39.4") or 1500mm (≈59.1"). When in doubt, size up slightly and use a tensioner to take up slack.
This belt uses the HTD (High Torque Drive) curvilinear tooth profile with a 5mm pitch. HTD-5M is not interchangeable with trapezoidal profiles such as MXL, XL, or L — and it is also not compatible with GT2 or GT3 pulleys despite the similar pitch. Always pair with HTD-5M rated pulleys.
HTD-5M belts are generally rated for moderate-to-high torque applications. The 20mm width typically handles greater loads than narrower 9mm or 15mm variants. Exact load ratings depend on pulley tooth count, operating speed, and wrap angle — consult your drive system's engineering specifications to confirm suitability for your application.
Neoprene HTD belts are generally resistant to light moisture and moderate temperatures (typically –20°C to +80°C / –4°F to +176°F). They are not recommended for prolonged submersion, direct oil contact, solvent exposure, or extended UV radiation without additional shielding. For harsh environments, contact us to confirm suitability.
No. Although GT2 and HTD-5M share a 5mm pitch, their tooth profiles are different. GT2/GT3 use a modified curvilinear profile that is not interchangeable with HTD. Mixing belt and pulley profiles causes poor meshing, accelerated wear, and potential drive failure. Use only HTD-5M pulleys with this belt.
Each variant is named in the format HTD-5M [Teeth]Teeth [Length]mm. For example, "HTD-5M 240Teeth 1200mm" means 240 teeth and a 1200mm (≈47.2") circumference. Tooth count = Belt Length ÷ 5. If you know your required circumference in inches, multiply by 25.4 to convert to mm, then find the closest listed size.
HTD-5M 20mm belts are commonly found in CNC routers, laser cutters, 3D printers with high-torque axes, robotic arm joints, pick-and-place machines, and light industrial conveyor systems. The wider 20mm format is typically chosen over 9mm or 15mm when higher torque or greater lateral stiffness is required.
