Product Description
Spur gear module 2, z=57, with hub
This module 2 spur gear (57 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. 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 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.
What should I do if I need a non-standard module that is not currently in the standard range?
If time is short and you need a specific size, we offer professional 3D printing from modern glass-fibre-reinforced materials. It is an outstanding, durable solution for an urgently needed spare part, for prototyping or for gears with lower loads, allowing you to restore continuity of operation very quickly.
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.
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.
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.
