OEM spur sprocket from Stihl. Spur chain sprockets are durable, economical, simple to use, and very popular. The chain driving portion of the sprocket and the clutch cup are fused together, so when it wears out, you need to replace the whole component. The economic design makes it popular for consumer chainsaws. Spur sprockets do not come with bearings, and we recommend replacing the bearing for every 2 spur sprocket replacements.
