KDS1-12 is an injection-molded spur gear made of Duracon (M90-44), with a module of 1, 12 teeth, and a 20° pressure angle. It has a pitch diameter of 12 mm, an outside diameter of 14 mm, and a face width of 6 mm. The bore tolerance is -0.05 to -0.30 mm, with a slight increase possible at the center. The gear exhibits a bending strength of 0.44 N·m (0.045 kgf·m) and a weight of 1.10 g. Dimensional tolerance for this size falls under ±0.25 mm, as per the molded item tolerance table. The gear is designed for use with sintered metal bushings for proper bearing fit, and no heat treatment is applied to standard units. Backlash is specified as 0 to 0.60 mm. Caution is advised against secondary operations due to potential internal bubbles in the molded material.
