When you require robust and efficient spur gear solutions for your transmission system, our spur gears deliver core values of precision transmission, extended lifespan, and tailored customization. To address downtime from wear, noise issues, and short service life under harsh conditions, we offer three advanced material options: carburized steel heavy-duty gears (HRC 58–62, lifespan +200%), noise-reducing POM plastic gears (≤ 55 dB), and 316L stainless steel corrosion-resistant gears. Using 5-axis CNC grinding (ISO Class 5 precision) and modified tooth profile design, we ensure ≥ 98% transmission efficiency. Our proven results include 75% failure rate reduction in automotive lines, <0.005 mm pitch error in precision instruments, and zero corrosion for food machinery.
A spur gear is the simplest and most common type of gear — featuring straight teeth cut parallel to the shaft.
It transmits motion and power between parallel shafts efficiently and is widely used in gearboxes, conveyors, machinery, and automation systems.
Key characteristics:
Straight teeth, parallel to axis
Transmits motion between parallel shafts
Easy to manufacture and highly efficient
Ideal for medium-speed, moderate-load applications
Spur gears are used across industries where reliable and efficient torque transmission is essential:
Automotive: Timing gears, steering systems, gear pumps
Industrial Equipment: Conveyors, reduction drives, machine tools
Robotics: Motion control, low-noise power transmission
Aerospace: Actuators and secondary drives
Renewable Energy: Wind turbine subsystems
Consumer Electronics: Printers, appliances, power tools

When comparing helical gear vs spur gear, the difference is in tooth orientation. Spur gears have straight teeth, making them easier to manufacture and highly efficient at moderate speeds. Helical gears, with angled teeth, operate more quietly and handle higher loads but are more complex and costly. For many industrial applications, spur gears remain the optimal solution.
| Feature | Spur Gear | Helical Gear | Customer Impact / Use Case |
|---|---|---|---|
| Tooth Shape | Straight teeth parallel to shaft | Angled teeth cut diagonally | Helical gears run smoother & quieter |
| Efficiency | Higher (up to 98%) | Slightly lower due to sliding friction | Spur gears save power in low-speed use |
| Noise Level | Louder, especially at high speed | Quieter operation | Helical recommended for sound-sensitive systems |
| Load Capacity | Moderate | Higher due to more tooth engagement | Helical handles heavier torque |
| Axial Thrust | None | Generates axial thrust | Spur easier to mount, no thrust bearings |
| Manufacturing Cost | Lower | Higher due to complex machining | Spur gears more cost-effective |
| Applications | Simple gearboxes, conveyors, mechanical drives | Automotive gearboxes, compressors, industrial automation | Choose based on speed, torque, and noise needs |
Tips:
If you need simple, cost-efficient, high-efficiency power transmission, spur gears are the smart choice.
If your system demands quiet, high-speed performance, go for helical gears.
