The KDS1 series comprises injection-molded spur gears made from Duracon (M90-44) with a module of 1, 20° pressure angle, and JIS grade N12 precision. Gears in the series have 12 to 80 teeth, matching pitch diameters and face widths. Bore tolerances are -0.05 to -0.30 mm, and dimensional tolerances follow molded standards: ±0.40 mm for 19-30 teeth, ±0.50 mm over 30. Allowable bending torque for similar sizes ranges up to 3.5 N·m. Induction hardening is available as an option but reduces precision and bore tolerance. The gears require parallel shaft alignment, proper lubrication, and safety covers when exposed. Secondary operations are discouraged due to internal bubbles in the molded material.
