• Precision 0.6M Metric Pitch & 3.175mm Shaft Compatibility: Designed with a strict 0.6 metric pitch (module) and a precise 3.175mm bore, these pinion gears ensure a perfect mesh with standard 0.6M spur gears and a seamless fit on 3.175mm motor shafts.
• CNC-Machined from Hardened Steel for Maximum Durability: Constructed from high-quality hardened steel via CNC machining, these gears are built to withstand extreme pressure, high speeds, and heavy torque applications. They outperform and outlast plastic or soft metal gears, resisting wear and deformation for a consistently reliable performance during racing, crawling, or bashing.
• Ultra-Smooth & Quiet Power Transmission: The precision engineering guarantees an ultra-smooth engagement with your spur gear. This optimal mesh significantly reduces noise and vibration, ensuring quiet operation even under heavy load. This results in seamless power transfer from your motor to the wheels for superior driving performance.
