AT Timing Belt – AT3、AT5、AT10、AT20

AT timing belt is mostly used type in industry. It achieves economical drive solutions in the low to medium performance range.

Wear Resistant
High Efficiency
Low Maintenance

AT Timing Belt Description

Compared with T-type timing belt, AT-type synchronous belt is more precise, it is smaller and has higher efficiency in the same transmission ratio, suitable for fast speed (1000~10000r/min) occasions. The width of the top of the tooth is relatively narrow, and the base of the tooth is relatively wide, which reduces the pressure of the top of the tooth and reduces wear.

Puteken mainly offers AT3, AT5, AT10 and AT20 PU timing belt. High wear-resistant material and high strength design, which greatly improve belt life service and reduce replacement frequency.

How can AT timing belt avoid tooth skipping?

Ensure Alignment Accuracy: Ensure alignment accuracy of belt pulley and timing belt to avoid mismatch between belt teeth and pulley teeth.
Appropriate Tension: Keep the tension of the timing belt within the appropriate range to avoid too tight or too lose.
Avoid Overload: Do not expose the toothed belt to operating conditions exceeding its rated load.

Does AT timing belt support reverse bending?

AT timing belts can withstand reverse bending to some extent, but frequent reverse bending may accelerate aging and wear. For applications requiring frequent reverse bending, specially designed timing belts are recommended

Can we get belt sample before we place order?

Yes, of course, timing belt sample is available. Before placing formal order, we can send you small timing belt sample for you to check belt teeth model and material.

What are differences between T and AT series timing belt?

Tooth Shape Design: T series is standard trapezoidal tooth shape, while AT is enhanced trapezoidal tooth shape with deeper tooth root.
Load Capacity: T series synchronous belt is suitable for low or medium load, while AT is ideal for high load and high torque transmission.
Transmission Accuracy: Compared with T series toothed belt, AT has higher accuracy and favorable for more complex application situation.
