Product Description
Spur gear module 4, z=12, with hub, hardened
The spur gear module 4 with z=12 teeth (with hub) is a universal modular component whose parameters match the entire family of gears and gear racks of the same module. The tooth surface is induction hardened (45-55 HRC), so the gear better withstands high cyclic loads and operation in harsh industrial conditions.

Frequently asked questions
How do you measure a worn tooth to choose the right replacement?
It is best to measure the outside diameter (Dz) and count the teeth (Z), and calculate the module from the formula m = Dz / (Z+2); it is also worth measuring the bore diameter so that the replacement fits the same shaft without additional machining.
Does the tooth shape of a module gear affect smooth running?
Yes, the ideal involute profile achieved through precise machining ensures uniform power transmission. This prevents jerking that could lead to teeth breaking off under load.
Do you make module gears to special order?
Yes. In addition to ready-made gears from our warehouse, we can manufacture non-standard CNC gears based on your technical drawing. And if the machine is at a standstill and time matters to you, we will produce it using 3D printing from glass-fibre-reinforced materials.
How do you set the correct centre distance between two module gears?
The centre distance is the sum of the pitch diameters of both gears divided by two (a = (Dp1+Dp2)/2); too small a distance causes seizing, and too large a distance - excessive backlash and loss of quiet running.
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.
