This dual sprocket wheel (75 teeth & 21 teeth) is made of C45 medium carbon steel and designed for DIN standard roller chains. The outer sprocket is optimized for 08B-1 chains (pitch 12.7mm, 75 teeth), while the inner sprocket is designed for 06B-1 chains (pitch 9.525mm, 21 teeth).
With induction-hardened teeth (52±3 HRC), the sprocket provides excellent wear resistance and long service life. Its precision-machined bore and bolt holes ensure accurate installation, reliable torque transfer, and smooth chain engagement.
It is widely used in conveyor systems, automation equipment, agricultural machinery, packaging machinery, and heavy-duty power transmission, especially in dual-chain drive applications requiring synchronization.
