Spur gear module 4 z=19 with hub hardened

Product Description

Spur gear module 4, z=19, with hub, hardened

Gear module 4, z=19, 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.

Technical data

Frequently asked questions

Are module gears from different manufacturers with the same module interchangeable?

The meshing geometry (module, pressure angle) is standardised, so such gears will mesh with each other, but bore or hub dimensions may differ between manufacturers - when replacing, it is worth checking this before installation.

How does manufacturing gears on CNC machine tools eliminate gearbox noise?

Old casting methods or milling on worn machines produce irregularities in the order of tenths of a millimetre. Our CNC machining ensures a perfect tooth profile. The gears roll on each other smoothly, which results in a dramatic drop in decibels on the production floor.

How can you check whether two module gears will mesh with each other?

There is one absolute condition: both gears must have exactly the same module (e.g. m=2) and the same pressure angle (standard 20°). If the modules differ by even a fraction of a millimetre, the teeth will start to shear and the gearbox will be destroyed.

Can a module gear be painted or lacquered?

Yes, the external surfaces (sides, circumference) can be protected with lacquer, but the teeth and the mounting bore should remain clean, because the coating would change their actual dimensions and disrupt meshing with the other gear.

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.
