The Wacker Neuson Lock Ring DIN471 A12 is a genuine OEM component designed for the TH627 internal concrete vibrator. Sourced directly from Wacker Neuson, this lock ring meets the exact DIN 471 standard specification required for correct assembly and secure shaft retention on the TH627. Confirming your model number against part before ordering ensures a direct, trouble-free installation.
Key Features
- DIN 471 Standard Compliance — Manufactured to the DIN 471 external retaining ring standard, ensuring correct groove engagement and secure axial retention on the A12 shaft diameter.
- Genuine OEM Part — Supplied by Wacker Neuson as an authorized replacement, meaning material grade and dimensional tolerances match the original component exactly as built.
- Direct Installation Fit — Seats into the existing retaining groove without rework, maintaining proper shaft and bearing positioning within the vibrator assembly.
- Protects Internal Assembly Integrity — A correctly seated lock ring prevents axial movement of rotating components, which, if left unchecked, accelerates bearing wear and internal damage.
- Confirmed Fitment for TH627 — Verified against Wacker Neuson spare parts list 418-02 for the TH627 internal concrete vibrator series.
A lock ring, also known as an external retaining ring or snap ring, is a precision-stamped fastener that seats into a machined groove on a shaft to restrict the axial movement of components such as bearings, gears, or housings. In an internal concrete vibrator like the TH627, maintaining correct component positioning along the drive shaft is critical to smooth, consistent vibration output. When a lock ring becomes worn, deformed, or missing, components can shift axially during operation, leading to accelerated internal wear, vibration loss, and potential failure of the vibrator head.
