Product Description
Spur gear module 2, z=60, with hub
The spur gear module 2 shown, 60 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 base material is C45E structural steel (EN 10083-1) - a proven choice for gear transmission parts operating in European industry.

Frequently asked questions
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.
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.
Can module gears be bored out for non-standard shafts?
Yes, most module gears are supplied with a pilot bore, which allows them to be freely bored out, keyway-slotted and precisely fitted to the specific shaft size at the customer's premises.
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.
