ATS15 Polyurethane Timing Belts
ATS15 Polyurethane Timing Belts
The ATS15 is a 15mm pitch heavy-duty polyurethane timing belt designed for applications requiring maximum tensile strength and torque capacity. It fills the gap between the AT10 and AT20 pitches, delivering roughly twice the power capacity of AT10 while using smaller pulleys than AT20. This makes the ATS15 the preferred choice for space-constrained drives that still need heavy-duty power transmission.
Texas Belting stocks ATS15 belts in open-ended rolls, welded endless loops, and truly endless molded configurations with widths up to 150mm. Steel cord, stainless steel, and aramid tension members are available. Optional backings, machined modifications, and welded profiles can be added for conveying and material handling applications.

ATS15 vs. AT10 and AT20
The ATS15 sits between the AT10 and AT20 in terms of power capacity and pulley size requirements. It is the right choice when AT10 does not provide enough torque capacity but AT20 pulleys are too large for the available space.
| Belt | Pitch | Relative Power | Typical Applications |
|---|---|---|---|
| AT10 | 10mm | Baseline | Medium-duty automation, packaging, servo drives |
| ATS15 | 15mm | ~2x AT10 | Heavy industrial, large conveyors, high-torque drives |
| AT20 | 20mm | ~2.5x AT10 | Maximum power, mining and steel processing |
Common Applications
ATS15 belts are specified for equipment where high torque loads, long belt runs, or heavy-duty cycling conditions exceed the capacity of standard AT10 belts. Typical applications include heavy conveyor systems, steel processing lines, large-format CNC machines, injection molding machine clamping drives, sawmill equipment, industrial presses, and material handling gantry systems.
For conveying applications, ATS15 belts can be fitted with welded profiles and backing materials to handle heavy product transport and positioning tasks that exceed the capacity of narrower AT10-based conveyors.
Frequently Asked Questions
The ATS15 is a 15mm pitch polyurethane timing belt with a modified curvilinear tooth profile (ATS) designed for high-power industrial drives. It fills the gap between the AT10 and AT20 profiles, providing roughly twice the power capacity of AT10 with smaller pulleys than AT20.
ATS15 belts are available in widths of 25, 32, 50, 75, 100, and 150mm. All widths are available in open-ended, welded, and truly endless configurations.
The ATS15 provides approximately twice the power capacity of AT10 and about 80% of the power capacity of AT20, while requiring smaller pulleys than AT20. This makes ATS15 ideal for heavy-duty drives in space-constrained layouts where AT20 pulleys would be too large. For maximum absolute power with no space restrictions, AT20 is the stronger option.
ATS15 belts are commonly specified in heavy industrial applications including steel and metals processing, mining and aggregate equipment, large-format CNC machines, injection molding clamping drives, heavy conveyor systems, industrial presses, and sawmill machinery.
Yes. ATS15 belts are available in FDA 21 CFR 177.2600 compliant polyurethane with stainless steel tension members for food processing and pharmaceutical applications that require high power capacity in a hygienic belt design. See the food-grade timing belts page for details.
ATS15 belts are available with high-carbon steel cord (standard, maximum strength), stainless steel cord (corrosion resistant for washdown environments), and aramid/Kevlar cord (non-magnetic, lightweight applications). Steel cord is recommended for maximum power transmission. For guidance on choosing the right tension member, see the timing belt materials guide.
Yes. ATS15 belts support the full range of backing options including polyamide fabric (PAZ), rubber coatings (PAR/Supergrip), felt, and custom profiles. Modifications such as drilled holes, machined slots, welded cleats, and V-guides can be applied for specialized conveying and material handling applications.
The ATS15 uses its own 15mm pitch pulley profile. While it shares the same modified curvilinear tooth geometry as the AT-Series, ATS15 pulleys are specific to the 15mm pitch and are not interchangeable with AT10 or AT20 pulleys. Texas Belting stocks standard ATS15 pulleys and can supply custom-machined pulleys to specification. Contact us at 888-203-2358 for availability.
