Product Description
Spur gear module 2.5, z=34, with hub
This module 2.5 spur gear (34 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. The base material is C45E structural steel (EN 10083-1) - a proven choice for gear transmission parts operating in European industry.

Frequently asked questions
How does the operating temperature affect the choice of material for a module gear?
At high temperatures, C45E steel retains its properties much better than plastics, which can soften and lose tooth profile accuracy; in such cases steel (including stainless steel if moisture or steam is also present) is the safer choice.
Are module gears from different manufacturers with the same module interchangeable?
The meshing geometry (module, pressure angle) is standardised, so such gears will mesh with each other, but bore or hub dimensions may differ between manufacturers - when replacing, it is worth checking this before installation.
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.
Does a module gear require constant lubrication?
Enclosed gears (in speed reducers) run in oil or grease, while open systems (gear + rack) require periodic manual lubrication - without it, friction and tooth wear increase many times faster.
Where is this product used?
Used in industrial machine drives, gate and industrial door automation and as a spare part for existing module gear drives - you only need to keep the same module and pressure angle.
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.
