Product Description
Spur gear module 6, z=18, with hub, hardened
The spur gear module 6 shown, 18 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°. Made of C45E steel (EN 10083-1) with induction-hardened teeth (45-55 HRC) - a variant intended for the most intensively used drives.

Frequently asked questions
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.
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 backlash and why does it matter?
It is a small gap between mating teeth, necessary for lubrication and thermal tolerance; too little backlash leads to seizing and overheating, while too much leads to jerking and faster tooth wear.
How does the operating temperature affect the choice of material for a module gear?
At high temperatures, C45E steel retains its properties much better than plastics, which can soften and lose tooth profile accuracy; in such cases steel (including stainless steel if moisture or steam is also present) is the safer choice.
Where is this product used?
It performs well in power transmission systems in machine tools, production lines and sliding gates, where it works together with a gear rack of the same module.
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.
