Double helical gears also has been called herringbone gear . The precision Large Double Helical Gears delivers excellent load capacity and very smooth power transmission in massive-scale industrial applications. Its engineering with opposing helix angles that can inherently remove axial thrust, these gears eliminate the need for thrust bearings while achieving maximum transmission efficiency. Available in extensive size ranges to suit the most demanding heavy machinery, each gear is manufactured from high-grade case-hardened alloy steels with deep case depths. Precision grinding to the highest quality standards ensures optimal tooth contact, minimal vibration, and extended service life under continuous heavy loads. You could learn more at our this blog Herringbone Gear Guide: Design, Applications & Comparison for details information of herringbone gears advantages ,disadvantages ,features and regular applications.
Precision Large Double Helical Gears
Engineered for the World’s Most Demanding Heavy Industrial Applications
Our Precision Large Double Helical Gears are trusted across heavy industry where failure is not an option. In cement and mineral processing, they drive rotary kilns, vertical roller mills, and ball mills under continuous shock loading and extreme thermal cycles. For steel and metal production, these gears deliver reliable performance in rolling mills, traveling grates, and heavy plate handling equipment that must withstand high temperatures and repetitive impact. Bulk material handling operations—including stacker-reclaimers, bucket wheel excavators, and apron conveyors—rely on the balanced thrust design and high power density for 24/7 operation in dust-laden environments. Power generation facilities specify these gears for coal pulverizers, cooling tower drives, and hydroelectric turbine speed multipliers where operational availability is critical. In marine propulsion and offshore applications, the ability to handle high inertia starts and extreme torque demands ensures reliable performance under the most severe operating conditions.
