Product Description
Spur gear module 2.5, z=50, with hub, hardened
The spur gear module 2.5 shown, 50 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°. The teeth are induction hardened to 45-55 HRC, which significantly increases wear resistance and extends gear service life in heavily loaded transmissions.

Frequently asked questions
How do you choose a gear rack to match a specific module gear?
The principle is the same as when selecting two gears - the rack must have the same module as the drive gear. Remember to choose the right rack width, which should be equal to or slightly wider than the face width of the gear, in order to transmit the full torque.
What does the pressure angle mean in module gears and why is it usually 20°?
The pressure angle defines the inclination of the tooth flank. In European industry the standard is 20°, because it provides the optimal balance between tooth root strength and quiet gearbox operation. This avoids the phenomenon known as tooth undercutting on smaller gears.
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.
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.
Where is this product used?
Used in the construction and servicing of gear reducers and gear transmissions for agricultural and construction machinery, and wherever precise and repeatable torque transmission matters.
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.
