PU timing belt AT5 780 - Megadyne Megapower

PU timing belt AT5 780 – endless PU timing belt in AT5 profile

PU timing belt AT5 780 - Megadyne Megapower is a polyurethane timing belt in the Megadyne Megapower series. It has an AT5 profile with 5 mm tooth pitch, 780 mm pitch length and 156 teeth. The belt is used in synchronous belt drives, where the tooth engagement must transfer the movement without slip.

The tooth profile controls which type of timing pulley the belt can run on. The length and number of teeth indicate the belt's turn, while the width is adapted to the current belt routing.

With 156 teeth and 5.0 mm pitch, the pitch length of 780 mm matches the belt's synchronous dimensions. The pitch length describes the belt's turn along the pitch line and is the length used in conjunction with the pitch and number of teeth.

The width tolerance is +/- 0.50 mm, the thickness tolerance is +/- 0.15 mm, and the sleeve width tolerance is +/- 10 mm. The working temperature for standard Megapower is -25 °C to +80 °C.

AT5 profile and tooth pitch

AT5 is an AT profile with a 5 mm pitch. The profile has its own tooth shape and must be driven with pulleys made for AT5 .

AT5 is an AT profile and should be kept separate from other profiles with the same pitch. An AT5 belt should run in timing belt pulleys where the tooth shape matches this particular profile.

Polyurethane and steel cord

The construction consists of polyurethane and zinc-coated steel cord. The polyurethane forms the teeth and spine, while the steel cord contributes to low elongation and stable pitch length.

The molded endless design provides a continuous belt without joints. This is an important difference compared to open or joined belts because the belt is made as one closed length from the start.

The standard version is thermoset polyurethane, standard 88 ShA with zinc-coated steel cord. The steel cord is located inside the belt and helps to keep the pitch length stable when the belt is operating in a synchronous drive.

Synchronous power transmission

The synchronous function comes from the tooth shape. When the belt and timing pulley fit together, the movement is maintained mechanically instead of relying on friction alone.

The standard widths for this belt are stated in the technical data. The width does not change the tooth pitch, but is part of the overall dimensions of the belt in the drive.

For this AT5 belt, the standard widths are 6, 8, 10, 12, 16, 20 and 25 mm. The width does not change the tooth profile, but it must fit the timing belt pulley, pulleybase and the space the belt has in the machine.
