Product Description (Detailed):

Enhance your mechanical designs and robotics projects with our high-quality Plastic Spur Gear – featuring 25 Teeth, a 40mm Diameter, 12mm Width, and a 6mm Centre Hole Diameter. This versatile plastic gear is an indispensable component for hobbyists, students, and engineers looking to create efficient and quiet power transmission systems. Ideal for applications requiring precise speed reduction, torque multiplication, or motion transfer between parallel shafts, this spur gear offers excellent performance.

Crafted from durable engineering plastic (often ABS or Nylon), this 25-tooth plastic gear provides several key advantages over metal alternatives. It's significantly lighter weight, contributing to reduced inertia in your systems and potentially lower power consumption. The material also inherently offers low noise operation and can often function effectively with minimal or even no lubrication, making it suitable for sensitive applications. The precise molding ensures accurate tooth profiles for smooth meshing and minimal backlash, vital for maintaining a constant velocity ratio. With a 6mm center bore, this gear is perfectly compatible with common DC motor shafts, geared motors, or standard axles found in many DIY and robotics kits. Its 40mm outer diameter and 12mm width provide a robust profile for reliable engagement in gear trains, robotic arms, differential systems, and custom mechanical setups. Whether you're designing a custom gearbox, building a remote-controlled vehicle, or experimenting with complex mechanical linkages, this plastic spur gear offers the perfect combination of durability, low friction, and precision for your next project.

The 25T Spur Gear is a precisely molded plastic gear designed for mechanical motion transfer in robotic drive systems, gearboxes, and DIY mechanical setups. Its 40mm diameter makes it suitable for moderate torque tasks, while the 6mm bore fits most standard DC motor shafts or shaft couplers.

The gear’s 12mm thickness allows robust engagement with mating gears, ensuring smooth, backlash-free transmission in robot arms, differential systems, motorized carts, or custom 3D-printed mechanisms.

Perfect for students, makers, and robotics hobbyists building gear trains or experimenting with mechanical transmission ratios.
