Product Description
Spur gear module 2.5, z=85, plate wheel
The module 2.5 gear with z=85 teeth (plate wheel) is a versatile module component, matched in its parameters to the entire family of gears and gear racks of the same module. 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 do you calculate the outside diameter from the number of teeth and the module?
It is very simple maths, often used by maintenance departments. The formula is: Dz = m * (Z + 2). For example, for a gear with module 3 and 20 teeth, the outside diameter will be: 3 * (20 + 2) = 66 mm.
Why is precise machining of module gears crucial for drive service life?
A precisely cut tooth involute guarantees that the gears roll on each other without micro-impacts or slippage. This reduces friction lowers the operating temperature and dramatically extends the service life of the entire gearbox.
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.
How does manufacturing gears on CNC machine tools eliminate gearbox noise?
Old casting methods or milling on worn machines produce irregularities in the order of tenths of a millimetre. Our CNC machining ensures a perfect tooth profile. The gears roll on each other smoothly, which results in a dramatic drop in decibels on the production floor.
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.
