Product Description
Spur gear module 4, z=15, with hub, hardened
Gear module 4, z=15, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). The tooth surface is induction hardened (45-55 HRC), so the gear better withstands high cyclic loads and operation in harsh industrial conditions.

Frequently asked questions
How do you choose a gear rack to match a specific module gear?
The principle is the same as when selecting two gears - the rack must have the same module as the drive gear. Remember to choose the right rack width, which should be equal to or slightly wider than the face width of the gear, in order to transmit the full torque.
Are the gear wheels for sliding gates also module gears?
Yes, the classic gate drive gear is a module gear working with a gear rack fixed to the gate leaf. This is usually module 4 (m=4), and for intensive commercial use precision-machined components are chosen that run quietly and without jamming.
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.
How does the build quality of a Polish/European manufacturer reduce rolling resistance in the gearbox?
Cheap gears from unverified sources often have a rough tooth surface that acts like sandpaper, raising the temperature and the drive resistance. Our gears have a smooth working surface, which helps maintain the lubricating film and minimises energy losses.
Where is this product used?
Module gears of this type are used in speed reducers, machine gearboxes, CNC machine tools and in rack drives of sliding and entrance gates.
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.
