PU timing belt AT10 1240 - Megadyne Megapower

PU timing belt AT10 1240 – polyurethane timing belt with steel cord

PU timing belt AT10 1240 - Megadyne Megapower is an endless PU timing belt for synchronous belt drives. The profile is AT10, the pitch length is 1240 mm, and the belt has 124 teeth. The teeth work together with a timing belt pulley in the same profile, so that power and movement are transmitted precisely.

The belt is a technical spare part where the fixed dimensions must match the drive. This applies in particular to the tooth profile, pitch length, number of teeth and the width used on the machine.

Technical data for this Megapower timing belt

Here are the fixed dimensions and technical information for PU timing belt AT10 1240 - Megadyne Megapower: profile, pitch length, tooth pitch, number of teeth, material and standard widths.

With 124 teeth and 10.0 mm pitch, the pitch length of 1240 mm fits the synchronous belt dimensions. The pitch length describes the turn of the belt 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 +/- 0.30 mm, and the sleeve width tolerance is +/- 10 mm. The working temperature for standard Megapower is -25 °C to +80 °C.

AT10 profile and tooth pitch

With AT10 profile, the belt gets 10 mm tooth pitch in the AT series. The profile should be kept separate from T10, even though the tooth pitch is the same.

AT10 is an AT profile and should be kept separate from other profiles with the same pitch. An AT10 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.

Synchronous power transmission

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 AT10 belt, the standard widths are 10, 12, 16, 20, 25, 32, 50 and 75 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 1240 mm.

What does AT10 mean?

AT10 is a metric AT profile with 10 mm tooth pitch. It is to be used with AT10 timing belt pulleys.

Which timing pulley should the belt be used with?

The belt must be used with timing belt pulleys in AT10 profile and with a width that matches the drive.

How many teeth does the belt have?

This Megadyne Megapower PU timing belt has 124 teeth.

Brief summary

PU timing belt AT10 1240 - Megadyne Megapower is a cast endless PU timing belt in AT10 profile with 1240 mm pitch length and 124 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.
