Product Description
Spur gear module 2.5, z=19, with hub
The module 2.5 spur gear z=19 with hub is a precision gear transmission component designed to transmit high torques at a constant ratio. The standard material is C45E steel (UNI EN 10083-1), widely used in the construction of gear transmissions, gear racks and module drives.

Frequently asked questions
How should gears be stored correctly before installation?
Preferably in a dry room, protected against moisture and dust, with a light layer of preservative oil on the teeth and bore - especially important for C45E carbon steel, which can start to corrode without protection.
How do you set the correct centre distance between two module gears?
The centre distance is the sum of the pitch diameters of both gears divided by two (a = (Dp1+Dp2)/2); too small a distance causes seizing, and too large a distance - excessive backlash and loss of quiet running.
How can wear of the gears in a module gearbox be diagnosed?
Wear is easiest to spot from a change in the tooth profile - it becomes sharp at the tip, and the backlash increases dramatically, which shows up as loud knocking when the machine changes its direction of rotation.
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.
