Spur gear module 4 z=27 with hub hardened

Product Description

Spur gear module 4, z=27, with hub, hardened

Gear module 4, z=27, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). 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

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.

Why is the pilot bore in a module gear often smaller than required?

A "rough" bore allows you to bore it out yourself to the exact, non-standard size of the customer's shaft - a ready-made large bore from stock would rarely match the required size perfectly.

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.

How do you choose the gear material (C45E steel, stainless steel or plastic) for specific operating conditions?

C45E steel is a universal choice for most industrial drives, stainless steel performs well in humid or aggressive environments, and plastics are used for lower loads or when quiet running and lubrication-free operation matter.

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.
