Product Description
Spur gear module 8, z=15, with hub
The spur gear module 8 with z=15 teeth (with hub) is a universal modular component whose parameters match the entire family of gears and gear racks of the same module. The standard material is C45E steel (UNI EN 10083-1), widely used in the construction of gear transmissions, gear racks and module drives.

Frequently asked questions
Can a module gear be ordered with a number of teeth outside the standard catalogue range?
Yes, in addition to ready stock we also produce CNC gears to order with a non-standard number of teeth, and for short lead times we additionally print them using 3D technology from glass-fibre-reinforced plastics.
How do you cut a keyway in a module gear with a small hub?
In gears with a small hub, the keyway is slotted with great care so as not to weaken the wall above the tooth. If there is not enough space, we recommend dispensing with a standard key (feather key) in favour of mounting with clamping bushes (locking assemblies).
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.
Why is the pilot bore in a module gear often smaller than required?
A "rough" bore allows you to bore it out yourself to the exact, non-standard size of the customer's shaft - a ready-made large bore from stock would rarely match the required size perfectly.
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.
