  1. Specification and model introduction
  2. Basic rated power meter
The AT20 rubber single-sided synchronization belt has a 20mm trapezoidal pitch. They are used in medium and large drives. The AT20 rubber single-sided tooth synchronous belt is designed to carry 30% more load than the T20 rubber single-sided tooth synchronous belt. The tooth shape of AT is large, which minimizes the deformation of the belt teeth and has a larger area of distribution of the belt load. The AT20 rubber single-sided tooth synchro belt is further enhanced by the addition of tough yarn. So AT20 rubber single-sided tooth synchronous belt is a kind of transmission synchronous belt with high load force.

AT20 rubber single-sided synchronous belt tooth spacing:

25mm, 32mm, 50mm, 75mm, 100mm

The width of the AT20 rubber single-sided synchronization belt can be determined according to customer requirements.

AT20 rubber single-sided synchronous belt design features:

The AT20 rubber single-sided synchronous belt is designed for durable and energy efficient power transmission and linear transmission operations. They are primarily used for endless and open action, with various sizes, structures and toothed designs handling a wide range of loads. AT20 rubber single-sided tooth synchro belt urethane is very wear-resistant, fatigue-resistant, and very flexible at the same time. Product quality is visible through numerous details. Tight and accurate tolerances enable perfect tooth meshing.

AT20 rubber single-sided synchronous belt Identification:

Three parts: Indicates the length, spacing, and width of the belt brought back by the part number. As shown in the following picture. This AT20 rubber single-toothed synchronous belt model has a length of 1500mm and a bandwidth of 50mm.
