Understanding technical features

On this page you will find a little glossary with the main technical terms connected with STIHL guide bars.

Risk of kickback

Kickback is a sudden uncontrolled movement of the chainsaw and this is one of the most dangerous situations that can occur when using a chainsaw. It happens when the saw chain in the area of the upper quarter of the guide bar nose unintentionally comes into contact with wood or a solid object. STIHL guide bars are optimised in terms of a reduced kickback tendency.

Number of teeth on sprocket nose

The number of teeth on the sprocket nose affects the properties of a Rollomatic E guide bar. Sprocket noses with up to 10 teeth have a lower kickback tendency than models with 11 or more teeth. The more teeth the sprocket nose has, the higher the cutting performance. This is especially so when working with the bar nose.

Pitch

The sprocket nose pitch allocates a Rollomatic guide bar to a particular sprocket and a particular chain pitch.

Bar length

The bar length determines the application and the number of drive links in the chain.

Groove width

Lateral control of the saw chain is provided by a continuous groove around the perimeter of the guide bar through which the drive links run. The groove also channels the chain oil. The chain slides over the guide bar between the lugs that remain at both sides.
