The gear has a module of 3, 18 teeth, a 54 mm pitch diameter, a 60 mm outside diameter, a 30 mm face width, and a 17 mm hub bore. It features a 20° pressure angle, JIS grade N9 precision, and standard full-depth teeth. Allowable torque is 1.75 N·m (0.18 kgf·m), with a backlash range of 0~0.54 mm. The weight is 0.28 kg. The gear is designed for high dimensional stability and operates reliably at temperatures up to 140°C. The steel core is mechanically bonded via diamond knurling and groove profiling, eliminating the need for adhesives or mechanical fasteners.
