The gear is manufactured from MC901 nylon, which provides a balance of strength and lightweight properties. It has a pressure angle of 20¬8 and standard full-depth teeth, ensuring compatibility with other gears of similar specifications. The tooth hardness ranges from 115 to 120 HRR, indicating good wear resistance.
