Gear Products


When it comes to gears, Delta is in a league of our own. Using the latest technology, seasoned machine operators, highly-experienced manufacturing engineers and spiral bevel technology experts, we produce some of the world’s finest gears – from one prototype part to full production of up to 2 million pieces per year.

In fact, Delta’s newest Klingelnberg G60 Spiral Bevel Gear and Curvic Coupling Grinder (our second G60) is considered one of the best gear spiral bevel grinders in the industry. Combined with our P40 & P65 Digital Electronic Gear Measuring System and its KIMoS 5 Bevel Gear and Centric Curvic design software, Delta has optimized the use of its closed loop system. This results in low set-up times, accurate bevel gear inspection and quick, flexible production cycles.

Delta meets your total value proposition – precision, consistency, quality and on-time-delivery.

We have what you need:

  • Spiral Bevel Gears – Hypoid & Zerol:
    • If you’re looking for high precision spiral bevel gears, look no further than Delta Research. Our CNC Klingelnberg G60 Spiral Bevel Gear Grinder, combined with the powerful Klingelnberg KIMoS closed-loop grinding system allows for flawless execution and quick, flexible service. From production truck axle ring and pinions and differentials to the most difficult aerospace spiral bevels, the Delta Family of Companies can support your spiral bevel and hypoid gear needs.
  • Clutch Components:
    • Whether you need wet or dry clutch components, The Delta Family of Companies can help you. We manufacture a wide variety of dog clutches, synchronizers, shift forks, clutch carriers, hubs and more. We handle the job from start to finish including any welding required.

  • Internal & External Helical Gears:
    • One of the future trends in the gear industry is in applying high loads in a small package. There is no better way of doing this than by using a planetary gear set. This, at one time, was the design revolution of transmission gearing; however, with the advancement of the electrification of vehicle motors, the vibrations and noise created by these planetary sets (due to gear error) has caused the industry to design their EV transmissions without the planetary ring gear included in it. Well, times are changing and with the help of Delta Research, you can design a planetary gear set that will have the precision needed to meet your NVH validation and your budget in both the prototype and production quantities.
  • Timed Gears:
    • Whether you are in an automotive industry or the aerospace industry, there are times when you have timed gears. From starter gears, to planetary cluster gears, The Delta Family of Companies has made some of the most precise timed gears and shafts required. Our equipment is designed to take the risk out of making your gears to print. For more information on your timed gear needs, click here.

  • Internal & External Ring Gears:
    • Whether you are making final drive gears or internal helical gears for a planetary gear set, the need for high-precision rings continues to increase in all industries. The Delta Family of Companies can help you with hard finished internal gears in both low and high-volume applications with outstanding quality and repeatability. No longer are the days where hard finished internal gears are too expensive for production volumes. To learn more about Delta’s capabilities on internal and external ring gears, click here.
  • Scissor Gears and assemblies:
    • Scissor Gears for balance shaft and engine applications require full understanding of gear tolerance, timing to hole features and grenade pin assembly requirements. At Delta Research, we pride ourselves in having all of the above. For more information on how Delta Research can help you with your scissor gears, click here.
