Description
Overview:
This circlip 8x0.8 (Stihl reference 9456 621 0570) is a hardened-steel retaining ring used to hold components on an 8 mm shaft and prevent axial movement. Commonly fitted to Stihl equipment such as the SP 81 chainsaw and BC-KM KombiTool attachments, it sits in a machined groove to keep bearings, gears, washers or sprockets correctly located. The 0.8 mm section provides a precise, low-profile fit that supports smooth running under vibration and load. Its external design with plier holes allows straightforward installation and removal using standard circlip pliers, making it suitable for routine servicing or repairs. Correct sizing helps restore proper end-float and alignment, maintaining drive reliability and reducing wear in rotating assemblies.
Key Features:
- Size matched for 8 mm shafts with 0.8 mm section for accurate fit
- External circlip profile for positive retention in shaft grooves
- Hardened steel construction for durability in high-vibration tools
- Supports correct end-float and alignment of gears, bearings and drums
- Straightforward to fit and remove with external circlip pliers
- Stihl reference: 9456 621 0570 for quick identification and ordering
- Suitable for a range of Stihl handheld and Kombi attachments
Typical Applications:
Used to secure bearings, gears, sprockets, clutch drums and spacers on shafts in outdoor power equipment. Ideal during maintenance tasks such as gearbox repairs, drive assembly rebuilds or bearing replacement on chainsaws and KombiTools. Helps prevent components drifting along the shaft, reducing noise, vibration and premature wear during regular use.
