Description
Overview:
This genuine Stihl Tensioner Slide is a small but critical part of the chain tensioning mechanism on professional chainsaws such as the 084 and MS 880. It is designed to transfer movement from the adjuster screw to the guide bar, allowing precise setting of chain tension for safe, efficient cutting. Made from a durable, oil‐resistant polymer in a compact black form factor, it withstands daily workshop and site conditions. Correct tension reduces wear on the bar, sprocket and chain, and helps prevent derailment. As an OEM component (Part No. 1124 640 1900), it provides the correct geometry and smooth travel required for reliable adjustment and consistent performance over time in demanding forestry, arborist and construction use.
Key Features:
- Genuine Stihl part for assured compatibility and fit
- Designed to maintain accurate, stable chain tension under load
