PU timing belt AT5 450 - Megadyne Megapower

PU timing belt AT5 450 – AT5 timing belt from Megadyne

PU timing belt AT5 450 - Megadyne Megapower is a cast endless Megapower PU timing belt with AT5 profile. The length along the pitch line is 450 mm and the number of teeth is 90. The belt transmits power via tooth engagement and is used in synchronous technical drives.

The pitch length is the length of the belt measured along the pitch line. Together with the tooth pitch and the number of teeth, it describes the synchronous dimensions of the belt in the drive.

Technical data for this Megapower timing belt

Here are the fixed dimensions and technical information for PU timing belt AT5 450 - Megadyne Megapower: profile, pitch length, tooth pitch, number of teeth, material and standard widths.

With 90 teeth and 5.0 mm pitch, the pitch length of 450 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.

Molded endless construction

The belt material is polyurethane and the standard reinforcement is zinc-coated steel cord. This provides a dimensionally stable PU timing belt for synchronous drives where the length must be kept uniform.

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.

Operation with timing belt pulleys

The timing belt transmits power by the teeth engaging the timing belt pulley. In a correctly constructed belt drive, this provides synchronous operation because the belt follows the rotation of the timing belt pulley without working as a friction belt.

The belt can be supplied in the standard widths listed in the technical data. The tooth profile and pitch length are the same, while the width follows the selected belt guide.

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.

Frequently asked questions about the product

What does pitch length mean?

The pitch length is the length of the belt measured along the pitch line. For this belt, the pitch length is 450 mm.

What does AT5 mean?

AT5 is a metric AT profile with a 5 mm tooth pitch. It is to be used with AT5 timing belt pulleys.

Which timing pulley should the belt be used with?

The belt must be used with timing belt pulleys in AT5 profile and with a width that matches the drive.

How many teeth does the belt have?

This Megadyne Megapower PU timing belt has 90 teeth.

Brief summary

PU timing belt AT5 450 - Megadyne Megapower is a cast endless PU timing belt in AT5 profile with 450 mm pitch length and 90 teeth. The belt is made of polyurethane with zinc-coated steel cord and is used for synchronous power transmission together with timing belt pulleys in the same profile.
