The KDS1 series comprises injection-molded spur gears made of Duracon (M90-44) with a module of 1 and a 20° pressure angle, designed for low-noise, high-torque applications. Each gear features a standard full-depth tooth profile and a bore tolerance of -0.05 to -0.30 mm. The KDS1-56 variant, while not explicitly listed, shares the series specifications including a 56-teeth count, 56 mm pitch diameter, 58 mm outside diameter, and a face width of 8 mm. It has an allowable bending strength of 4.5 N·m and a weight of approximately 23.6 g. Bore tolerances may vary slightly at the center, and the gears have an inherent backlash of 0 to 0.60 mm. Secondary operations are not recommended due to potential internal bubbles in the molded material.
