KDS1-40 is a module 1, 40-tooth injection-molded spur gear made from Duracon (M90-44), with a pressure angle of 20° and JIS grade N12 precision. It has a bore diameter of 16 mm, an outside diameter of 42 mm, and a face width of 14 mm. The gear has a tooth hardness of 110 to 120 HRR, a bending strength of 2.33 N·m, and weighs 8.39 g. Backlash ranges from 0 to 0.60 mm. The bore tolerance is -0.05 to -0.30 mm, with potential slight variation at the center. It is designed for use with sintered metal bushings and requires proper center distance and parallel shaft alignment to ensure even tooth contact and minimize noise or wear.
