T5 AT5 Open Ended Timing Belt — Precise Synchronous Drive for CNC, 3D Printing & Linear Automation

Engineers, makers, and machine builders know the frustration of a drive belt that slips, stretches, or arrives in a fixed loop that doesn't fit their custom frame. Whether you're building a CNC router, repairing a 3D printer gantry, or designing an industrial conveyor, you need an open-ended timing belt you can cut to exact length — without compromising on tooth accuracy or tensile strength.

This listing covers T5 and AT5 open-ended PU timing belts with a 5mm pitch (tooth-to-tooth spacing). Each belt is sold by the meter and available in six widths: 10mm (approx. 3/8"), 15mm (approx. 19/32"), 20mm (approx. 25/32"), 25mm (approx. 1"), 30mm (approx. 1-3/16"), and 40mm (approx. 1-9/16"). Lengths range from 1 meter (approx. 39.4") up to 10 meters (approx. 393.7"). The belt body is molded from polyurethane (PU) reinforced with a steel or fiberglass tension cord, delivering low elongation and consistent tooth pitch across the full run.

Typical use cases include CNC router X/Y axis drives, 3D printer open-loop belt systems, laser cutter gantry assemblies, pick-and-place linear actuators, and light-duty conveyor belt replacements. The open-ended format lets you terminate with standard belt clamps, crimp connectors, or custom end fittings — making it a go-to choice for DIY automation and machine repair projects.

ℹ️ Compatibility Notice: T5 belts require T5-profile pulleys; AT5 belts require AT5-profile pulleys. The two tooth profiles are not interchangeable. Confirm your pulley profile and flange width before ordering.

✅ Key Features of These T5 AT5 Open Ended PU Timing Belts

  • ⚙️5mm Pitch Accuracy — Consistent tooth-to-tooth spacing of 5mm across the full belt length ensures repeatable positioning in CNC and linear drive applications.
  • ✂️Cut-to-Length Flexibility — Open-ended format lets you trim to any custom length on-site with a utility knife, eliminating the need to source fixed-loop belts in non-standard sizes.
  • 🧱Polyurethane (PU) Construction — PU material resists oils, greases, and moderate moisture better than rubber, and maintains tooth geometry under sustained load without cracking or glazing.
  • 📐Six Width Options (10–40mm) — Choose the belt width that matches your pulley flange, from narrow 10mm belts for lightweight 3D printer drives to wide 40mm belts for heavier conveyor or automation duty.
  • 🔩Reinforced Tension Cord Core — Internal steel or fiberglass reinforcement cord minimizes belt elongation under tension, keeping your drive system in sync over long linear runs without frequent re-tensioning.
  • 🔄T5 & AT5 Profiles Available — Standard T5 trapezoidal tooth for general synchronous drives; AT5 modified profile for smoother engagement and reduced backlash in precision positioning systems.

❓ Frequently Asked Questions

How do I choose the right length for my T5 or AT5 open-ended timing belt?

Measure the total travel distance of your axis or conveyor run, then add allowance for tensioning and termination hardware. For reference, 1 meter is approximately 39.37 inches and 5 meters is approximately 196.9 inches. Order slightly longer than your minimum requirement so you can trim to an exact fit on-site.

What is the difference between T5 and AT5 timing belts?

Both share a 5mm pitch (tooth-to-tooth spacing). The AT5 profile features a modified, more rounded tooth geometry that generally provides smoother engagement and reduced backlash compared to the standard T5 trapezoidal tooth. AT5 is often preferred in precision positioning applications such as CNC routers and laser cutters.

What load or tension can these PU timing belts handle?

Allowable working tension varies by belt width. Wider belts carry higher loads — a 40mm belt typically handles significantly more tension than a 10mm belt. Consult your drive system's engineering specifications for exact load ratings. PU belts generally offer higher tensile strength than comparable rubber belts of the same profile.

Are these timing belts suitable for outdoor or humid environments?

Polyurethane (PU) timing belts are generally more resistant to oils, greases, and moderate moisture than rubber belts. They perform well in indoor industrial and workshop environments. For prolonged outdoor UV exposure or immersion in liquids, contact us to confirm suitability for your specific conditions.

What pulleys are compatible with T5 and AT5 open-ended timing belts?

T5 belts require T5-profile pulleys (5mm pitch, trapezoidal tooth). AT5 belts require AT5-profile pulleys. The two profiles are not interchangeable. Verify your pulley's tooth profile and pitch before ordering. Standard T5/AT5 pulleys are widely available in aluminum and steel for shaft diameters from 4mm to 20mm and beyond.

Can I cut this open-ended belt to a custom length?

Yes. Open-ended timing belts are designed to be cut to any length using a sharp utility knife or belt cutter. Cut between teeth for a clean edge. This makes them ideal for linear actuators, CNC machines, and conveyor systems where a specific run length is required.

Which width should I choose for my application?

Narrower widths (10–15mm) suit lightweight 3D printers and small plotters. Medium widths (20–25mm) are common in CNC routers and mid-duty linear drives. Wider belts (30–40mm) are typically used in heavier conveyor systems or high-torque automation equipment. Match the belt width to your pulley flange width.
