0.3m Micro Spur Gear

FAQ– Micro Spur Gear M0.3

Q1. What Is A Micro Spur Gear M0.3 And Its Key Features?

A micro spur gear m0.3 is a small module precision gear designed for compact mechanical systems requiring high accuracy and smooth motion. These gears typically have a module of 0.3, outer diameters ranging from 14 mm to 32 mm, and fine teeth height of 0.675 mm. Our micro spur gears are manufactured using CNC machining, gear hobbing, and grinding, achieving tooth profile error ≤10 μm and surface roughness as low as Ra 0.2. They are ideal for applications such as humanoid robots, aerospace equipment, and high-precision instruments, where reliability and repeatable performance are critical.

Q2. What are the main applications of micro precision gears?

Micro precision gears are widely used in humanoid robots, medical devices, aerospace instruments, automation equipment, and micro-mechanical systems. These gears are essential for smooth motion, precise torque transmission, and high efficiency in confined spaces. In humanoid robots, micro gears control limb movement, joint rotation, and fine actuation. In aerospace applications, they are part of flight instruments, sensors, and control mechanisms, where tight tolerances and aerospace-grade reliability are required. Their small size, high accuracy, and long-term durability make them the preferred choice for advanced robotics and critical systems.

Q3. Can micro spur gears be custom manufactured?
