Description
Overview:
This genuine Stihl tension spring (part number 1122 160 5500) is a small but vital component that helps keep your chainsaw's mechanisms working smoothly. Made from durable metal, it provides reliable elastic force within the saw's tensioning and control assemblies, helping parts return to position and maintain correct operating pressure. Designed specifically for Stihl professional saws, it offers a precise fit and dependable performance on heavy‐duty machines such as the MS660 and MS640. As an OEM component, it matches the original specification for consistency and longevity. Fitting a fresh spring as part of routine maintenance helps prevent slack, reduces the risk of poor tension control, and supports clean, efficient cutting under load.
Key Features:
- Genuine Stihl OEM part for assured fit and compatibility
- Durable metal construction for long service life in demanding use
- Maintains correct tensioning force for consistent cutting performance
- Stable operation under vibration and high loads typical of large pro saws
- Designed for the MS 640/MS 660 platform for easy, direct replacement
- Helps restore precise control after wear or fatigue in older springs
- Straightforward to install with standard workshop tools
Typical Applications:
Ideal for routine servicing or repair of Stihl professional chainsaws where spring force is critical to reliable operation. Use when restoring a saw that struggles to hold tension, after a strip-down and clean, or whenever the original spring shows signs of fatigue, corrosion, or loss of elasticity. Suitable for workshop rebuilds, site repairs, and preventative maintenance schedules.
