More cutting performance due to higher chain speed!

Increase the efficiency of your chainsaw with an 8-tooth pinion: More teeth mean greater circumferential movement per revolution – and thus a higher chain speed. Ideal for those who want to work quickly and powerfully.

Calculation example for chain speed:

The speed of the chain (in meters per second) is calculated as follows:

Chain speed = (engine speed × number of teeth × pitch) ÷ 60

With 7 teeth: 10,000 × 7 × 0.009525 ÷ 60 = 11.11 m/s

With 8 teeth: 10,000 × 8 × 0.009525 ÷ 60 = 12.70 m/s

Result: The chain speed increases by about 14.3%

⚠️ Important note about practice:

A larger pinion increases speed – but not always effectiveness:

For soft coniferous wood or with a short rail, an 8-tooth pinion can be very useful.

However, with hard wood, long guide rails or weaker engine power, it can also lead to loss of performance or greater wear.

💡 Tip: Choose your pinion to suit your chainsaw and intended use.
