Product Description
Spur gear module 3, z=15, with hub, hardened
This module 3 spur gear (15 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. 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
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.
Can a module gear be ordered with a number of teeth outside the standard catalogue range?
Yes, in addition to ready stock we also produce CNC gears to order with a non-standard number of teeth, and for short lead times we additionally print them using 3D technology from glass-fibre-reinforced plastics.
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.
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.
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.
