Product Description
Spur gear module 4, z=57, plate wheel
The module 4 gear with z=57 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 gear is made of C45E steel (EN 10083-1); the involute tooth profile and 20° pressure angle ensure smooth, quiet meshing with gears or racks of the same module.

Frequently asked questions
How do you choose the gear material (C45E steel, stainless steel or plastic) for specific operating conditions?
C45E steel is a universal choice for most industrial drives, stainless steel performs well in humid or aggressive environments, and plastics are used for lower loads or when quiet running and lubrication-free operation matter.
Why is the pilot bore in a module gear often smaller than required?
A "rough" bore allows you to bore it out yourself to the exact, non-standard size of the customer's shaft - a ready-made large bore from stock would rarely match the required size perfectly.
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.
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.
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.
