Product Description
Spur gear module 2.5, z=29, with hub
The spur gear module 2.5 shown, 29 teeth, with hub, is a basic component of module drives - it meshes with any other gear or gear rack (toothed rack) of the same module and pressure angle 20°. The base material is C45E structural steel (EN 10083-1) - a proven choice for gear transmission parts operating in European industry.

Frequently asked questions
Are module gears from different manufacturers with the same module interchangeable?
The meshing geometry (module, pressure angle) is standardised, so such gears will mesh with each other, but bore or hub dimensions may differ between manufacturers - when replacing, it is worth checking this before installation.
In which applications do helical module gears perform well?
Helical teeth ensure smoother engagement, which drastically reduces noise and vibration at high rotational speeds. They are used in precision speed reducers and machine tools, bearing in mind, however, the need to use thrust bearings (absorbing axial forces).
Can module gears be bored out for non-standard shafts?
Yes, most module gears are supplied with a pilot bore, which allows them to be freely bored out, keyway-slotted and precisely fitted to the specific shaft size at the customer's premises.
How can you check whether two module gears will mesh with each other?
There is one absolute condition: both gears must have exactly the same module (e.g. m=2) and the same pressure angle (standard 20°). If the modules differ by even a fraction of a millimetre, the teeth will start to shear and the gearbox will be destroyed.
Where is this product used?
Typical applications include conveyor drives, packaging machines, industrial automation and positioning systems using a gear and gear rack pair.
When placing your order, please check the current stock level of this gear - the lead time depends on it and is clearly stated according to the quantity available in the given warehouse.
