Key Features
- OEM-Spec Retention Strength — Manufactured to Husqvarna's exact dimensional tolerances, this ring delivers the same secure hold as the original, preventing component movement under the load and vibration demands of core drilling.
- Direct Drop-In Replacement — Engineered to match the original mounting groove dimensions of the DM406, this Retainer Ring installs into position without modification or re-machining.
- DM406 Compatibility — Confirmed fitment for the DM406 concrete core drill motor, so you can order with confidence knowing this is the correct part for your machine.
- Structural Component Integrity — A correctly seated retainer ring keeps internal components locked in proper alignment during drilling operations, protecting surrounding parts from premature wear or displacement.
- Genuine Husqvarna OEM Part — Sourced directly from Husqvarna's construction equipment parts catalog, this component meets the same production standards as the part installed at the factory.
A retainer ring is a precision fastening component used to secure rotating or sliding parts within a housing or along a shaft, preventing axial movement during operation. In a core drill motor like the DM406, it holds critical internal components in their correct position, ensuring smooth power transfer and accurate drilling performance. When a retainer ring becomes worn, deformed, or damaged, the components it secures can shift, leading to increased vibration, accelerated wear on adjacent parts, and potential loss of drilling accuracy. Replacing it with the correct part — verified by cross-referencing part number 531119035 against your parts diagram — restores the assembly to its intended operating condition.
