The KDS1 series consists of injection molded spur gears made from Duracon (M90-44) with a module of 1 and a 20° pressure angle, conforming to JIS grade N12 precision. Gears in this series feature standard full-depth teeth, a bore tolerance of -0.05 to -0.30 mm, and are available with tooth counts ranging from 12 to 80. Each gear is sized to match its number of teeth, with corresponding pitch diameter, outside diameter, and face width as specified. The gears are designed for use with sintered metal bushings and require adequate backlash to avoid noise and wear. Secondary operations are not recommended due to potential internal bubbles in the molded material. The allowable bending strength, weight, and backlash vary by tooth count, with values provided for each documented variant in the series.
