Description
Overview:
This Genuine Stihl tensioner slide (part no. 1125 640 1900) is a small but critical chain adjustment component used on a wide range of Stihl chainsaws, including MS381 and MS441. Built from OEM-grade materials for wear resistance, it transfers movement from the adjuster screw to the guide bar to set and maintain correct chain tension. Keeping the chain correctly tensioned supports cutting performance, reduces premature wear, and improves safety. This slide is suitable for routine servicing or repair when the original part becomes worn, rounded, or seized, and is designed for straightforward replacement without special tools. As a genuine Stihl part, it provides the right fit and function to restore precise chain adjustment and smooth running of your saw.
Key Features:
- Genuine Stihl OEM component for assured fit and compatibility
- Transfers adjuster screw movement to the guide bar for accurate chain tension
- Robust, wear-resistant construction for long service life
- Helps maintain cutting efficiency and reduce bar, sprocket, and chain wear
- Stable tensioning improves safety by limiting chain slack or over-tension
- Precision-moulded/formed slide for consistent, repeatable adjustment
- Simple to fit during routine maintenance; no special tools required
- Suitable for professional, agricultural, forestry, landscaping, and DIY use
Typical Applications:
Replacement of a worn or damaged chain tensioner slide during bar and chain changes, full services, or repairs. Useful when chain tension drifts, the adjuster feels rough, or the bar no longer moves smoothly during adjustment. Common in forestry, arborist work, grounds maintenance, and firewood processing where reliable tensioning is essential.
