The Tamiya 54577 - 06 Module Hard Coated Aluminum Pinion Gear (21T) is produced from lightweight aluminium and finished with a hard coating to resist wear. This construction reduces rotating mass while offering improved surface protection for extended service.
Its rounded tooth design reduces contact stress and curbs friction between pinion and spur. The result is a smoother drive feel and reduced wear on both the pinion and the mating 06 Module spur gears.
Made to work with 06 Module spur gears, the pinion includes a 3mm grub screw to secure it to the motor shaft. Ensure correct mesh and tighten the grub screw to maintain a reliable fit during operation.
