Spur gear module 5 z=38 with hub

Product Description

Spur gear module 5, z=38, with hub

Gear module 5, z=38, with hub - a robust component for building and repairing gear transmissions, reducers and rack drives (gear rack + gear). The standard material is C45E steel (UNI EN 10083-1), widely used in the construction of gear transmissions, gear racks and module drives.

Technical data

Frequently asked questions

How does a module gear differ from a chain sprocket?

A module gear meshes directly with another gear or gear rack, while a sprocket works with a roller chain - they have a different tooth profile and are not interchangeable, even though they look similar from a distance.

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.

How does the operating temperature affect the choice of material for a module gear?

At high temperatures, C45E steel retains its properties much better than plastics, which can soften and lose tooth profile accuracy; in such cases steel (including stainless steel if moisture or steam is also present) is the safer choice.

Does a module gear require constant lubrication?

Enclosed gears (in speed reducers) run in oil or grease, while open systems (gear + rack) require periodic manual lubrication - without it, friction and tooth wear increase many times faster.

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.
