The Wacker Neuson External Retaining Ring 16mm x 1mm is a genuine OEM component designed for a wide range of Wacker Neuson portable generators, walk-behind trowels, and floor saws. As a direct factory replacement, this ring delivers the correct dimensional fit and material grade required to keep rotating shafts and assemblies securely retained. It is compatible with GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, and GPS6600A portable generators, CT30, CT36, and CT48 series walk-behind trowels, and BFS 935A, BFS 1335A, BFS 1345, and BFS 1350 series floor saws, among many additional models. Sourcing a genuine Wacker Neuson part like the ensures the ring meets the exact tolerances and temper spec of the original, protecting the integrity of the assembly it secures.
Key Features
- Exact OEM Dimensional Tolerance — Manufactured to the precise 16mm shaft diameter and 1mm groove width spec, ensuring the ring seats fully and holds without slippage or deformation.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, this is the same ring installed on the production line — no substitution guesswork.
- Broad Cross-Series Compatibility — Fits GP3800A, GP4000, GP5600A, GP6600A, GPS5600A, GPS6600A generators; CT30, CT36, and CT48 walk-behind trowel families; and BFS 935A through BFS 1350 floor saw models.
- Preserves Shaft and Bearing Alignment — A correctly seated external retaining ring keeps rotating components locked at the designed axial position, preventing premature bearing and shaft wear.
- Fast, Tool-Friendly Installation — Snap-ring profile installs with standard external circlip pliers — no special tooling or machining required to seat the ring in its groove.
An external retaining ring — sometimes called a circlip — is a thin, sprung metal ring that clips into a machined groove on the outside of a shaft or pin to prevent axial movement of the components mounted on it. It acts as a positive mechanical stop, keeping gears, bearings, pulleys, and other rotating parts from walking along the shaft during operation. When a retaining ring becomes worn, distorted, or snaps, the component it was holding can shift out of alignment or separate entirely, leading to accelerated wear on adjacent parts and potential loss of function in the assembly.
