25-tooth Plastic Gear

A 25-tooth plastic gear is commonly used in small mechanical and robotic applications, such as toy motors, servo modifications, and gearboxes.

Specifications:

1. Material: Usually made of ABS, nylon, POM (polyoxymethylene), or acetal, offering good durability and low friction.
2. Teeth: 25 teeth with a specific module (pitch size).
3. Module (M): Determines the tooth size and spacing (e.g., M0.5, M1, M1.5).
4. Bore Diameter (Hole Size): Typically ranges from 2mm to 8mm, depending on the shaft it fits.
5. Outer Diameter: Varies based on the module (e.g., an M1 gear with 25 teeth will have an outer diameter of about 27mm).
6. Thickness: Determines compatibility with gearboxes and motors.
7. Pitch Circle Diameter (PCD): Important for meshing with other gears.
8. Pressure Angle: Standard angles are 20° or 14.5° for smooth operation.

 Applications:

• Small DC motors and gearboxes
• Robotics and automation projects
• Toy car and RC vehicle repairs
• 3D printers and CNC machines
• DIY mechanical projects
