Description
Overview:
This retaining ring is a genuine Husqvarna part for securing components on shafts or in grooves within professional and domestic saws. Made from durable steel for high wear resistance, it prevents axial movement so parts stay correctly located during operation. It is designed for Husqvarna chainsaws and power cutters, including popular chainsaw models such as the 266 and 288. Typical uses include holding assemblies like clutch drums, sprockets, and bearings in place under vibration and high load. Using the correct OEM ring helps maintain safety, performance, and service life, especially on high‐output machines. Supplied to OEM specification with the correct section and fit to match the original groove design for consistent retention.
Key Features:
- Genuine Husqvarna part for assured fit and compatibility on listed models
- Helps stop components sliding off shafts, maintaining correct alignment and function
- Durable steel construction suited to high-vibration, high-load environments
- OEM geometry for reliable seating in the existing groove, reducing risk of failure
- Stable under heat and oil exposure typical of chainsaw and cutter applications
- Supports smooth servicing: straightforward to install and remove with standard circlip pliers
- Suitable for repeated maintenance cycles without deforming when fitted correctly
- Helps protect adjacent components (e.g. bearings, drums, sprockets) from unintended movement
- Husqvarna quality control for consistency across production batches
- Genuine Part status helps ensure the correct hardness and spring characteristics
Typical Applications:
Used to retain rotating or sliding parts on shafts or within bores in chainsaws and power cutters. Commonly fitted around clutch and sprocket assemblies, bearing carriers, and pulley hubs to prevent axial shift under load, vibration, and thermal cycling during cutting operations.
