Spur gear module 5 z=25 with hub hardened

Product Description

Spur gear module 5, z=25, with hub, hardened

This module 5 spur gear (25 teeth, with hub) is used wherever reliable, maintenance-free power transmission via involute gearing is required. Made of C45E steel (EN 10083-1) with induction-hardened teeth (45-55 HRC) - a variant intended for the most intensively used drives.

Technical data

Frequently asked questions

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 can wear of the gears in a module gearbox be diagnosed?

Wear is easiest to spot from a change in the tooth profile - it becomes sharp at the tip, and the backlash increases dramatically, which shows up as loud knocking when the machine changes its direction of rotation.

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.

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.

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.
