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.
