PU timing belt T2.5 277 - Megadyne Megapower

PU timing belt T2.5 277 – timing belt for synchronous power transmission

PU timing belt T2.5 277 - Megadyne Megapower is a Megadyne Megapower timing belt in polyurethane. It has a T2.5 profile, 277 mm pitch length and 110.8 teeth, and is intended for belt drives where the belt and timing belt pulley must follow each other without slip.

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.

With 110.8 teeth and 2.5 mm pitch, the pitch length of 277 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 +/- 0.30 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.

T2.5 profile and tooth pitch

The T2.5 profile has a 2.5 mm tooth pitch and belongs to the small metric T profiles. It is often used in compact synchronous belt drives where the belt must follow the timing pulley precisely over shorter lengths.

T2.5 is a T-profile and should be kept separate from other profiles with the same pitch. A T2.5 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.

Tooth engagement in operation

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 T2.5 belt, the standard widths are 4, 6, 8, 10 and 12 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 110.8 teeth.

What does T2.5 mean?

T2.5 means that the belt has a metric T-profile with 2.5 mm tooth pitch.

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 277 mm.

Which timing pulley should the belt be used with?

The belt must be used with timing belt pulleys in T2.5 profile and with a width that matches the drive.

Brief summary

PU timing belt T2.5 277 - Megadyne Megapower is a cast endless PU timing belt in T2.5 profile with 277 mm pitch length and 110.8 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.
