Description
Overview:
This deflection limiter is a Genuine Husqvarna OEM component designed for professional petrol chainsaws such as the 545 and 556. Made from tough pressed steel with a durable finish, it stabilises the chain run and limits unwanted movement under load, helping the saw maintain correct alignment and smooth cutting performance. By controlling deflection, it reduces wear on nearby parts and supports reliable chain brake operation. Manufactured to Husqvarna tolerances and supplied under MPN 505125801 (505 12 58-01), it is a direct-fit replacement for compatible Husqvarna models. Suitable for workshop servicing or field repairs, it restores correct function when the original limiter is bent, worn, or missing, helping keep your saw safe, accurate, and ready for demanding work.
Key Features:
- Genuine Husqvarna OEM part for assured compatibility and fit
- Precision steel construction for impact and wear resistance
- Maintains chain line stability to reduce vibration and uneven cutting
- Helps protect adjacent components by preventing excessive chain movement
- Direct replacement using factory mounting points; straightforward to fit
- Built to withstand wet, cold, and dusty conditions on site or in woodland
- Engineered clearances support consistent performance across the rev range
- Ideal for restoring performance after accidental knocks or heavy use
Typical Applications:
Used during chainsaw maintenance or repair to restore correct chain path control. Common in forestry, arborist work, estate and grounds maintenance, landscaping, and firewood processing. Fit when the original limiter is damaged, missing, or causing misalignment that leads to poor cutting accuracy or premature wear.
