The KSSG1.5-21 is a precision ground steel spur gear featuring 21 teeth and a plain bore. It is manufactured from S45C material and has undergone induction hardening, resulting in a tooth hardness of 50 to 60 HRC. The gear is designed with a standard full depth tooth profile and a pressure angle of 20¬8. The surface treatment includes a black oxide coating, which is applied to all areas except the teeth. This gear is suitable for applications requiring high durability and precision, but secondary operations on the tooth areas are not recommended due to the hardening process. The gear's dimensions include a pitch diameter of 25.5 mm and an outside diameter of 34.5 mm, with a face width of 9.12 mm. The allowable torque for this gear is 2.12 N¬?m.
