Our company offers a replacement for the Fenner brand worm reducer. Our products are of high quality with affordable prices. It is important to note that our products are replacement parts and not original equipment. If you need to purchase original equipment, please contact the original supplier. Our worm gear reducers are modular in design and made of modern aluminum, providing a reliable and cost-effective solution. They are made of lightweight aluminum gearboxes that are both rigid and strong, ensuring long-term reliable operating life.



When choosing a gear reducer for your application, consider the following factors:

The performance of the gear reducer depends on correct installation, lubrication, and maintenance. For shaft mounting, make sure the shaft and gear unit holes are clean and free of burrs. Apply a sufficient amount of lubricating oil on the shaft and hole to assist in installation and prevent corrosion. Insert the unit onto the driven shaft. Install the keys, but do not use tape or top-fixed keys. For foot mounting, securely mount the equipment on a sturdy structure and install output extension shafts as required. Connections between shafts should use flexible couplings, and make sure the shaft deviation is within the range of the coupling's tolerance. Do not hammer the shaft when installing or removing the drive components, as it will damage the bearings.

Regularly check if the components are clean, especially the cooling area. Check for oil leakage, especially around the oil seal. Make sure the vent hole on the plug is clean and use an oil window to check if there is enough lubricating oil. If in doubt, we recommend that you completely empty the lubricating oil in the gearbox and clean the gearbox before adding new lubricating oil to remove any residue.

| Problem | Cause | Solution |
|---|---|---|
| Overheating | Insufficient lubrication | Check the lubrication system |
| Excessive noise | Worn gears or bearings | Replace the worn components |
| Oil leakage | Damaged seals | Replace the damaged seals |
Worm gear reducers require electric motors to drive them. Our company offers various electric motors for sale and can provide solutions tailored to your specific needs. The correct selection of the electric motor is essential for achieving optimal performance of the gear reducer. The two are interdependent, and it is crucial to choose the right motor for your worm gear reducer to ensure the longevity and optimal performance of your equipment.
