Product Description
Spur gear module 4, z=33, with hub, hardened
The spur gear module 4 shown, 33 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
What lubrication is optimal for open module (rack) gear drives?
For open systems (gear + gear rack), it is best to use thick greases with added graphite or copper, which adhere firmly to the teeth and are not flung off by centrifugal force. In very dusty applications, dry Teflon lubricants perform better.
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.
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.
In which applications do helical module gears perform well?
Helical teeth ensure smoother engagement, which drastically reduces noise and vibration at high rotational speeds. They are used in precision speed reducers and machine tools, bearing in mind, however, the need to use thrust bearings (absorbing axial forces).
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.
