Product Description
Spur gear module 2, z=47, with hub
Gear module 2, z=47, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). 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
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.
Do you make module gears to special order?
Yes. In addition to ready-made gears from our warehouse, we can manufacture non-standard CNC gears based on your technical drawing. And if the machine is at a standstill and time matters to you, we will produce it using 3D printing from glass-fibre-reinforced materials.
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.
How do you calculate the ratio of a gear pair of two module gears with different numbers of teeth?
The ratio is calculated as the quotient of the number of teeth of the driven gear to that of the driving gear (i = Z2/Z1); the module must be identical for both gears, otherwise meshing will not work at all.
Where is this product used?
Typical applications include conveyor drives, packaging machines, industrial automation and positioning systems using a gear and gear rack pair.
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.
