Product Description
Spur gear module 3, z=18, with hub
The module 3 spur gear z=18 with hub is a precision gear transmission component designed to transmit high torques at a constant ratio. Made of C45E steel (UNI/EN 10083-1), which ensures high mechanical strength and wear resistance during prolonged operation under load.

Frequently asked questions
How does a module gear differ from a chain sprocket?
A module gear meshes directly with another gear or gear rack, while a sprocket works with a roller chain - they have a different tooth profile and are not interchangeable, even though they look similar from a distance.
What is profile shift and when is it used?
It is a slight shift of the tooth profile relative to the standard profile, used mainly with a very small number of teeth to avoid undercutting the tooth root; in typical stock applications it is not required.
What is the difference between a gear with hub (PM) and a plate wheel (CM), and when should you choose which?
The hub extends the part axially and makes mounting on the shaft easier (more room for a key or a clamping ring), while the plate wheel is flat and lighter - it is chosen when the design already has its own bearing arrangement/mounting and the gear only has to transmit the meshing.
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.
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.
