A spur gear is a cylindrical toothed gear with teeth that are parallel to the axis of rotation. They are the most common type of gears used in various mechanical applications due to their simplicity, efficiency, and cost-effectiveness. Spur gears transmit motion and power between parallel shafts, offering high load capacity and reliability. These gears are widely utilized in industries such as automotive, aerospace, manufacturing, and robotics.

Choosing our spur gears ensures several benefits that enhance performance and reliability:
What is a spur gear used for?
Spur gears are primarily used to transmit motion and power between parallel shafts in various mechanical systems, such as vehicles, machinery, and appliances. They are ideal for applications requiring high load capacity and efficiency.
How do I select the right spur gear for my application?
Consider factors like load requirements, speed, material compatibility, environmental conditions, and space constraints. Our technical team can assist in choosing the appropriate module, number of teeth, and material based on your specific needs.
What materials are best for spur gears?
Steel is preferred for high-strength applications, brass offers good corrosion resistance, and plastics like nylon or acetal are used for lightweight, quiet operations. The choice depends on factors like load, noise, and environment.
Can spur gears be used in high-speed applications?
Yes, but they may produce more noise compared to helical gears. Using precision-machined gears with proper lubrication can mitigate noise and ensure smooth high-speed operation.
How do I maintain spur gears?
Regular inspection for wear, proper lubrication, and ensuring alignment can extend gear life. Avoid overloading and operate within specified limits to prevent damage.
What is the difference between spur gears and helical gears?
Spur gears have straight teeth parallel to the axis, while helical gears have angled teeth. Helical gears operate more quietly and smoothly but are more complex and costly. Spur gears are simpler and more efficient for many applications.
Are custom spur gears available?
Yes, we offer custom spur gears tailored to your specifications, including unique sizes, materials, tooth profiles, and tolerances. Contact us with your requirements for a quote.
What standards do your spur gears comply with?
Our gears meet international standards such as AGMA (American Gear Manufacturers Association) and ISO (International Organization for Standardization), ensuring quality and reliability.
