Product Description
Spur gear module 2.5, z=32, with hub
The spur gear module 2.5 shown, 32 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 (UNI/EN 10083-1), which ensures high mechanical strength and wear resistance during prolonged operation under load.

Frequently asked questions
Can a module gear be painted or lacquered?
Yes, the external surfaces (sides, circumference) can be protected with lacquer, but the teeth and the mounting bore should remain clean, because the coating would change their actual dimensions and disrupt meshing with the other gear.
Do straight-tooth module gears have a specific mounting direction?
No, a straight-tooth gear is symmetrical and can be mounted either way round; direction only matters with helical teeth, where the helix angle must match the mating gear.
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.
How do you choose the gear material (C45E steel, stainless steel or plastic) for specific operating conditions?
C45E steel is a universal choice for most industrial drives, stainless steel performs well in humid or aggressive environments, and plastics are used for lower loads or when quiet running and lubrication-free operation matter.
Where is this product used?
Module gears of this type are used in speed reducers, machine gearboxes, CNC machine tools and in rack drives of sliding and entrance gates.
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.
