At Shreeji Gears, we manufacture precision helical rack and pinion sets designed for smooth linear motion, high positional accuracy, and heavy load handling. Our 20-degree helical rack and pinion systems provide quieter operation, improved load distribution, and enhanced durability compared to straight-tooth racks.
The rack is manufactured with an 800 mm effective width, while the pinion is supplied with a precision-machined boss to ensure secure mounting, accurate alignment, and reliable torque transmission.
⚙️ What Is a Helical Rack and Pinion?
A helical rack and pinion converts rotary motion into linear motion using angled teeth cut at a helix angle. The 20-degree helical tooth profile allows gradual tooth engagement, resulting in smoother motion, reduced noise, and higher load-carrying capacity.
Helical rack and pinion systems are widely used in applications requiring precise positioning, continuous motion, and heavy-duty performance.

🔧 Helical Rack & Pinion Manufacturing Process
Manufacturing helical rack and pinion systems requires precise control of tooth geometry and alignment to ensure smooth and accurate linear motion.
- Raw Material Selection: High-grade steel selected as per load and duty cycle.
- Rack Machining: Milling and preparation of 800 mm rack blank.
- Helical Tooth Cutting: Precision cutting of 20° helical teeth.
- Pinion Turning: Machining of OD, face width, and boss.
- Pinion Gear Cutting: Accurate helical tooth generation.
- Heat Treatment: Enhanced surface hardness and wear resistance.
- Keyway / Spline Machining: Secure torque transfer.
- Deburring & Finishing: Smooth engagement and reduced backlash.
- Quality Inspection: Tooth profile, pitch accuracy, alignment, and runout checks.
This ensures smooth travel, reduced vibration, and long operational life even in heavy-duty applications.
