Helical Gears

Rolling Mill Machines provides high quality Single and Double Helical Gears manufactured in compliance with international gear manufacturing standards. Our helical gears are produced using high grade raw materials such as steel, stainless steel, and alloy steel to ensure excellent strength, durability, accuracy, and long service life.

Every gear undergoes thorough inspection by experienced professionals using advanced technology and precision machinery to maintain consistent quality and reliable performance.

Helical gears feature angled teeth that provide smoother and quieter operation compared to conventional spur gears. Their higher contact ratio enables efficient power transmission and greater load carrying capacity while reducing noise and vibration.

Single Helical Gears generate axial thrust during operation, while Double Helical Gears, also known as Herringbone Gears, incorporate opposing left hand and right hand helices to balance axial forces. This design provides stable operation, reduces thrust on bearings, and can contribute to extended bearing life.

Our Single and Double Helical Gears are widely used in marine gearboxes, rolling mills, steel plants, heavy equipment manufacturing, and other demanding industrial applications. We also offer custom manufactured gears according to specific client requirements.
