Product Description

Spur gear module 5, z=28, with hub

Gear module 5, z=28, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). Made of C45E steel (UNI/EN 10083-1), which ensures high mechanical strength and wear resistance during prolonged operation under load.

Technical data

Frequently asked questions

How do you cut a keyway in a module gear with a small hub?

In gears with a small hub, the keyway is slotted with great care so as not to weaken the wall above the tooth. If there is not enough space, we recommend dispensing with a standard key (feather key) in favour of mounting with clamping bushes (locking assemblies).

Can module gears be bored out for non-standard shafts?

Yes, most module gears are supplied with a pilot bore, which allows them to be freely bored out, keyway-slotted and precisely fitted to the specific shaft size at the customer's premises.

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.

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.

Where is this product used?

Typical applications include conveyor drives, packaging machines, industrial automation and positioning systems using a gear and gear rack pair.
