AT3 PU Trapezoid Synchronous Belt

Working Temperature:
Rubber: -20°C to +80°C
Polyurethane (PU): -30°C to +80°C

Key Features
Precision Positioning:
50° trapezoidal tooth profile ensures deep meshing with minimal backlash, ideal for servo positioning and linear modules.
High Rigidity & Low Elongation:
Reinforced with steel cords, delivering near-zero stretch and significantly higher accuracy than 3M curvilinear profiles.
Enhanced Anti-Tooth Jumping Performance:
Thicker tooth root design improves resistance to shock loads, frequent start-stop conditions, and overload without tooth skipping.
High-Speed Capability:
Maximum linear speed ≤ 45 m/s, suitable for high-speed servo systems operating at 1,000–10,000 rpm.
Clean & Low Dust:
Polyurethane material ensures low particulate generation, suitable for cleanroom environments and electronic equipment.
Maintenance-Free Operation:
No lubrication required, with transmission efficiency ≥ 98%.

Typical Applications
Servo motor drives
Linear modules and linear stages
3D printers
Dispensing machines
Pick-and-place machines (SMT)
