CNBTR 72 Teeth Steel Pinion Gear 6mm Shaft Hole 0.5M Spur Gear for DIY

Description

Product Overview

The CNBTR 72-tooth steel pinion gear is engineered for precision and durability in a compact form factor. Made from high‑grade 45# steel, the gear provides excellent strength while maintaining a lightweight profile of just 0.704 ounces. Its 0.5M module and 6mm shaft hole are carefully machined to achieve tight tolerances, ensuring smooth meshing with mating gears and reducing backlash in low‑torque applications. The gear is designed for non‑load use up to eight hours, delivering consistent performance without overheating. With a standard 72‑tooth count, it fits a wide range of spur gear assemblies, making it a versatile component for hobbyist projects, educational kits, and prototype builds. The product dimensions of 5 x 3.3 x 0.4 inches allow easy integration into confined spaces, while the robust steel construction resists wear and corrosion, extending the service life of the gear even under frequent handling. This pinion gear is a reliable choice for anyone needing a high‑quality, small‑size gear that balances precision, strength, and affordability.

Usage

Designed with the DIY community in mind, this pinion gear excels in a variety of practical scenarios. It is perfect for building micro‑generators, where the gear ratio and smooth operation directly affect output efficiency. Small machinery such as hobby‑grade CNC routers, miniature conveyor systems, and educational robotics kits benefit from the gear’s precise tooth geometry and reliable concentricity. The 6mm shaft hole aligns with standard motor shafts and small‑scale drive shafts, allowing seamless installation without the need for additional adapters. Users can also incorporate the gear into custom wind‑up toys, clock mechanisms, and experimental power‑transmission setups. Because the gear is rated for non‑load use, it is best suited for applications where the load is intermittent or low, such as demonstration models, prototype testing, and educational demonstrations. Its compact size makes it easy to mount on bench tops or within confined enclosures, and the steel material ensures the gear can withstand repeated cycles without deformation. Whether you are a hobbyist, a student, or a small‑business prototype developer, this gear provides a dependable solution for precise motion control in lightweight projects.

FAQ

What is the maximum load this gear can handle?

The gear is rated for non‑load use up to eight hours, making it suitable for low‑torque applications such as prototypes, educational models, and micro‑generators. For higher load requirements, a gear with a larger module or reinforced design is recommended.

Can I use this gear with a motor that has a 5mm shaft?

The gear’s shaft hole is 6mm, so it will not directly fit a 5mm shaft. However, you can use a simple sleeve or adapter to bridge the size difference, allowing secure attachment to a 5mm motor shaft.

Is the gear compatible with other CNBTR gear sizes?

Yes, the gear follows standard spur gear dimensions, so it meshes well with other CNBTR gears that share the same module (0.5M) and appropriate tooth counts. This makes it easy to create gear trains with consistent performance.

How do I ensure proper alignment during installation?

Start by cleaning the shaft and gear bore to remove any debris. Apply a thin layer of compatible grease to the shaft, then gently press the gear onto the shaft, ensuring the gear’s bore aligns centrally. Use a set screw or keyway if available to lock the gear in place and prevent slippage.

What warranty does CNBTR provide for this gear?

CNBTR offers a one‑year limited warranty covering manufacturing defects. If you encounter any issues related to material quality or workmanship, contact our support team for a replacement or refund, subject to verification of the defect.
