Brass Pinion Gear GOTOTOP Rack Pinion 9 Tooth 5mm Mini Motor

Description

Product Overview

The GOTOTOP 2PCS Brass Pinion Gear set combines meticulous engineering with premium materials to deliver a reliable solution for miniature motor and gear applications. Each gear features a precise 9‑tooth profile machined into high‑grade brass, offering a 5 mm pitch diameter that aligns perfectly with standard mini‑motor shafts. The brass alloy is specially formulated to resist corrosion, reduce wear, and maintain dimensional stability even under high‑speed rotation, ensuring consistent performance over extended use. Both gears are pre‑drilled with a centered bore that matches common motor shaft diameters, allowing for tool‑free installation and immediate operation. The compact package dimensions (0.79 × 0.39 × 0.39 in) and lightweight design (0.176 oz per gear) make the set ideal for space‑constrained assemblies, while the robust construction provides the durability required for demanding robotics and DIY projects.

Usage

Designed with versatility in mind, this gear set excels in a wide range of scenarios. It integrates seamlessly with the Duplo Intelli Lok Module 0.4, making it a perfect replacement part for hobbyists who need to restore or upgrade their existing kits. Beyond Duplo, the gears are compatible with numerous small‑scale mechanical assemblies, including educational STEM models, custom robotics platforms, and hobbyist drone motor upgrades. Whether you are building a classroom demonstration of gear ratios, a prototype for a micro‑robotic arm, or a DIY mechanical clock, the 9‑tooth brass pinion delivers smooth power transmission and reliable torque conversion. The corrosion‑resistant finish ensures that the gears perform consistently in environments that may involve humidity, light exposure, or occasional contact with lubricants, extending the lifespan of your projects.

FAQ

What motor shaft sizes are compatible with these gears?

The gears are designed with a standard 2 mm bore, which fits most miniature DC motor shafts used in hobbyist robotics and educational kits. If your shaft differs slightly, the brass material can be gently re‑bored with a fine drill to achieve a perfect fit.

Can I use these gears in high‑speed applications?

Yes. The brass alloy maintains structural integrity at high rotational speeds, and the precise tooth geometry minimizes backlash, making the gears suitable for applications up to several thousand RPM when properly lubricated.

Are the gears interchangeable with other brands?

While the 9‑tooth 5 mm pitch is a common standard, it is recommended to verify the module and tooth count of any third‑party gear before mixing. The brass material and tooth profile are compatible with most systems that adhere to the same specifications.

How do I maintain the gears for optimal performance?

Periodically inspect the teeth for wear and clean any debris with a soft brush. Applying a thin layer of light machine oil can reduce friction and protect against corrosion, especially if the gears are used in dusty or humid conditions.

What is the warranty period for this product?

GOTOTOP offers a 12‑month limited warranty covering manufacturing defects. If you encounter any issues related to material quality or workmanship, contact the seller for a replacement or refund.
