Ms 380 Stihl Circlip Retaining Ring 25x1.2 for 038 MS380 MS381 Saws 9455 621 2790

The Stihl Circlips DIN471-25x1.2 9455 621 2790 are precision-engineered from high-strength spring steel, adhering to DIN 471 standards for reliable axial retention in high-stress mechanical systems. These external retaining rings, measuring 25mm in inner diameter with a 1.2mm thickness, securely fasten bearings, gears, or shafts to prevent lateral movement, making them ideal for maintaining structural integrity in rotating components of pressure washers and chainsaws. Specifically compatible with Stihl RE 580 W, RE 550 W, and RE 520 W pressure washers, as well as MS 381 chainsaws and Viking HE-series equipment, they ensure seamless operation under extreme rotational speeds or oscillating loads. Their durable construction and corrosion-resistant finish make them essential for both OEM replacements and industrial maintenance, particularly in power transmission systems requiring secure, long-lasting component fixation.
