What Is a Herringbone Gear?
A herringbone gear is basically a double helical gear with the teeth on one side being left-handed and the other right-handed. Because the two tooth directions offset each other in axial force, the gear remains very quiet and stable even at high speed and heavy load. Double helical herringbone gears can deliver the following benefits as compared to single helical ones:
lower vibration.
less noise.
higher load-carrying capacity.
better stability in long-term operation.
We are capable of making different varieties of helical and herringbone gears. Besides this, we also produce large-diameter ring gears, pinions, and other heavy-duty transmission components for mining and industrial machinery.

Service & Support:
Our goal is to be more than a mere parts provider—we strive to be partners in our customers’ mission of improving their equipment's reliability and reducing downtime.
Old part replication: We can recreate a part that is severely worn out by using its original shape.
Material traceability: Every raw material batch can be traced.
100% quality-checked: All gears are accompanied by full inspection reports.
Engineer-supported selection: Helps to decrease mismatch risk during installation.
Global export expertise: Compliant with customs and documentation requirements.
Shipping options: Sea, land, rail, or air freight.
Quick and clear quotes: Helps to shorten the communication process.
Applications:
Herringbone gears find their use mostly in heavy industrial equipment, like:
Mining crushers and screening lines.
Ball mills and rotary kilns.
Large gear reducers.
Steel mill and metallurgical equipment.
Cement production machinery.
Conveying and port handling systems.
Hoisting and travel mechanisms.
These machines are very heavy-duty, and can be considered as operating in severe conditions. To ensure stable performance for the long term, herringbone gears are used there.
FAQ:
Q1: What size herringbone gear can you make?
We work with diameters ranging from 300 mm to 8000 mm. Just let us know the kind of gear you need and we will come up with the best solution for you.
Q2: Can you manufacture a new one if I only have a sample that is worn or damaged?
Absolutely. We are able to measure it, recreate the geometry, and make a brand-new identical replacement.
Q3: In which countries are you allowed to deliver?
Our shipping capability spans the entire globe; that is to say, we deliver to Asia, Europe, the Americas, Africa, the Middle East, and Australia.
Why Customers Trust Us?
Our main goal is not only to produce high-quality gears, but also to provide the best service for your equipment, thus increasing its life with less breakdowns.
We don't leave anything to chance when it comes to quality: each gear is accompanied by a full set of inspection documents.
We have been intensely engaged in heavy industry metalworking for over two decades, particularly in the fields of mining, steel mills, and cement plants.
With a strong experience in international trades, we know what overseas buyers are looking for and we are ready to fulfill their needs.
There are several nice features of this model: Transparent pricing, quick response, and facilitating after-sales support.
First of all, the single-row jaw layout is a natural one for the coupling you are dealing with, making it both a very compact and highly compatible unit. Motors, pumps, gearboxes, and most standard industrial shafts are what it operates efficiently with. Provided that the bore size is compatible, the installation can hardly take more than a few minutes and is very simple.
During the start-up or the shut-off of a system, the flexible spider plays its role in absorbing the shocks and thus decreasing the noise and vibration. In this way, not only does the system operate at a more stable level, but also the life of the equipment is prolonged.
