Spur gear module 3 z=30 with hub hardened

Product Description

Spur gear module 3, z=30, with hub, hardened

Gear module 3, z=30, 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

What lubrication is optimal for open module (rack) gear drives?

For open systems (gear + gear rack), it is best to use thick greases with added graphite or copper, which adhere firmly to the teeth and are not flung off by centrifugal force. In very dusty applications, dry Teflon lubricants perform better.

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.

Does the tooth shape of a module gear affect smooth running?

Yes, the ideal involute profile achieved through precise machining ensures uniform power transmission. This prevents jerking that could lead to teeth breaking off under load.

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?

Used in the construction and servicing of gear reducers and gear transmissions for agricultural and construction machinery, and wherever precise and repeatable torque transmission matters.

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.
