PU timing belt AT5 375 - Megadyne Megapower

PU timing belt AT5 375 – endless PU timing belt in AT5 profile

PU timing belt AT5 375 - Megadyne Megapower is a polyurethane timing belt in the Megadyne Megapower series. It has an AT5 profile with 5 mm tooth pitch, 375 mm pitch length and 75 teeth. The belt is used in synchronous belt drives, where the tooth engagement must transfer the movement without slip.

The most important measurements for the belt are profile, pitch length, tooth pitch, number of teeth and width. When these measurements match the timing belt pulley, the belt will have a clean tooth mesh and a stable operation in the drive.

Technical data for this Megapower timing belt

Here are the fixed dimensions and technical information for PU timing belt AT5 375 - Megadyne Megapower: profile, pitch length, tooth pitch, number of teeth, material and standard widths.

• Product: PU timing belt AT5 375 - Megadyne Megapower
• SKU: MP AT5 -375

With 75 teeth and 5.0 mm pitch, the pitch length of 375 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.

Belt construction

The timing belt is made of polyurethane and has zinc-coated steel cord as reinforcement. Polyurethane provides a durable timing belt, while the steel cord helps the belt maintain a stable length during operation.

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.

Function in the belt drive

In operation, the teeth work directly in the timing belt pulley. This makes the belt suitable for synchronous movements, where the shafts must follow each other with fixed timing.

The standard widths make it possible to use the same profile and length in multiple widths. This is convenient when the machine's timing belt pulleys and space requirements require a specific belt width.

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

How many teeth does the belt have?

This Megadyne Megapower PU timing belt has 75 teeth.

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.

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 375 mm.

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.

Brief summary

PU timing belt AT5 375 - Megadyne Megapower is a cast endless PU timing belt in AT5 profile with 375 mm pitch length and 75 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.
