Frequently Asked Questions
Shreeji Gears is recognized as one of the best helical gear manufacturers in Ahmedabad, India, and also supplies globally. We produce high-precision gears up to DIN 5–8 accuracy, module 1.5M to 16M, 800 mm OD, and 150 mm face width with reliable quality and on-time delivery.
Helical gears are used where quiet and smooth operation is required, especially in high-speed and high-load applications.
Helical gears provide smoother and quieter operation due to gradual tooth engagement, making them suitable for high-speed and high-load systems.
Yes, we manufacture custom helical gears as per client specifications and international quality standards.
Helical gears run more smoothly and quietly than spur gears because their angled teeth engage gradually. They handle higher loads and are ideal for high-speed applications.
The helix angle is the angle of the gear teeth relative to the gear axis. A higher helix angle improves smoothness and load capacity but increases axial thrust.
Helical gears generate axial thrust, require thrust bearings, produce more sliding friction, and are more expensive to manufacture than spur gears.
Common materials include alloy steel, carbon steel, stainless steel, brass, bronze, and engineering plastics like nylon and acetal.
Helical gears are manufactured using hobbing, shaping, grinding, and heat treatments such as carburizing and nitriding.
Precision is measured using AGMA, DIN, or ISO standards through checks for profile error, lead error, runout, and surface finish using advanced gear testing machines.
Helical gears are used in automotive transmissions, gearboxes, compressors, turbines, pumps, printing machinery, and marine propulsion systems.
Cost depends on material, module, face width, precision level, helix angle, and manufacturing process. Precision-ground gears are more expensive than hobbed gears.
Lead time ranges from a few days for small quantities to several weeks for large or complex gears requiring heat treatment or grinding.
Yes, we offer reverse engineering. We analyze the sample gear, create CAD drawings, and manufacture with precise tolerances.
Types include single helical gears, double helical gears (herringbone), and crossed-axis helical gears for special applications.
Axial thrust is managed using thrust bearings or by using double helical (herringbone) gears that cancel opposing forces.
They require high-quality mineral or synthetic gear oil with EP (Extreme Pressure) and anti-wear additives to reduce friction and prevent wear.
Common issues include wear, misalignment, noise, and overheating. Proper lubrication, accurate alignment, and quality materials reduce failures.
We require module/DP, number of teeth, face width, helix angle, material, hardness, bore type, and required quantity.

The Shreeji Gears Helical Advantage
A trusted helical gear manufacturer in Ahmedabad, India delivering precision, performance, and long-lasting reliability.
Engineered for Silent & High-Speed Performance
Helical gears are preferred for their quiet operation—and we refine this advantage to perfection. Using advanced CNC hobbing and profile grinding, Shreeji Gears ensures accurate helix angle, superior tooth finish, and smooth, gradual gear meshing. The result: minimum vibration, low noise, and stable performance at very high RPM, ideal for automotive, industrial, and gearbox applications worldwide.
Axial Thrust Management Expertise
Helical gears naturally generate axial thrust—and managing it correctly is critical for long gear life. Our engineering team provides recommendations for the correct thrust bearings and design configurations. For high-torque or heavy-load industries, we also manufacture specialized Double Helical (Herringbone) Gears that eliminate thrust forces completely and offer smoother, more efficient power transmission.

How Helical Gears Are Manufactured
Helical gears can be manufactured on the same hobbing machines as spur gears by tilting the hob to the helix angle. However, the twisted tooth geometry requires advanced CNC hobbing, shaping, and grinding systems to ensure high precision and smooth power transmission.
Manufacturing Reference Systems
Two reference systems are used in helical gear production:
1. Transverse (Radial) Module Helical Gears
- Reference in the rotating plane
- Center distance matches spur gears with same module and teeth
- Spur gear replacement possible
- Needs special helical hobs and grinding wheels
- Higher manufacturing cost
2. Normal Module Helical Gears
- Reference taken in the normal plane
- Can be manufactured using standard spur gear hobs & grinding wheels
- Lower tooling cost
- Center distance does not match spur gears
- Center distances become non-integer
Axial Thrust in Helical Gears
Due to angled teeth, helical gears generate axial thrust, which must be handled with thrust bearings or special structural support. Proper alignment and load distribution are crucial for long-term reliability.
Double Helical / Herringbone Gears
- Opposing helix angles eliminate axial thrust
- Perfect for high-load industrial and marine applications
- Used in heavy-duty, large power transmission systems
Advantages of Single Helical Gears
- Easier to manufacture and assemble
- Allows flexible alignment corrections
- Ideal for custom engineered gear solutions
Advantages of Helical Gears

Efficiency of Helical Gears
Helical gears offer an efficiency of 90% to 99.5%, depending on lubrication, alignment, and load distribution. Their rolling engagement creates smoother operation and higher performance than spur gears.
In-Depth Guide to Helical Gear Design
Understand the engineering behind high-performance helical gears.
What Defines a Helical Gear?
A helical gear has teeth cut at an angle, known as the helix angle. This angled profile allows gradual meshing, improving smoothness, reducing noise, and increasing load-bearing capacity.
The Critical Role of the Helix Angle
A higher helix angle results in quieter, smoother operation but increases axial thrust. For parallel shaft applications, one gear must have a Right-Hand (RH) helix, and the mating gear must have a Left-Hand (LH) helix with the same angle.
Managing Axial Thrust
Helical gears produce axial thrust force parallel to the gear axis. Proper thrust bearings must be used to avoid movement, wear, and misalignment. For systems requiring zero thrust, Double Helical (Herringbone) Gears are ideal.
