Frequently asked questions
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.
Why is precise machining of module gears crucial for drive service life?
A precisely cut tooth involute guarantees that the gears roll on each other without micro-impacts or slippage. This reduces friction lowers the operating temperature and dramatically extends the service life of the entire gearbox.
How can you recognise a manufacturing defect in a gear when receiving the goods?
It is worth checking the radial runout (the gear should not "wobble" on the shaft), the uniformity of the pitch between teeth and the smoothness of the tooth surface - visible burrs, dents or uneven pitch are a signal to file a complaint.
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.
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.
