Description
Overview:
This genuine Stihl chain sprocket is a precision drive component for the MSA 220 C-B battery chainsaw. Made from hardened steel for wear resistance, it transfers power from the motor to the saw chain and helps maintain smooth, consistent chain speed. The sprocket has a 3/8 inch Picco pitch (9.53 mm) with 6 teeth for correct engagement with compatible low‐profile chains. It is designed as a direct replacement for OEM No. 1251 642 1204 and fits the Stihl MSA 220 C-B and MSA220C models. Using the correct sprocket helps reduce chain skip, improves cutting efficiency, and protects other drive parts from premature wear, supporting reliable performance during regular professional and domestic cutting tasks.
