The Wacker Neuson Nilos Ring 6012Zav is a genuine OEM sealing ring designed for CRT36 and CRT48 series ride-on concrete trowels. Sourced directly from Wacker Neuson, this part carries the same specifications as the component installed at the factory, ensuring a correct fit within the bearing assembly. Compatible models include the CRT36-24A, CRT36-25, CRT36-26A, CRT48-25K-L, CRT48-25K-H, and CRTv36-26A, among others in the CRT family. When a Nilos ring wears or fails, bearing contamination and accelerated wear follow quickly — replacing it with the correct OEM part keeps the rotor assembly running cleanly.
Key Features
- OEM Sealing Integrity — Manufactured to Wacker Neuson's exact profile and material spec for the 6012Zav bearing position, ensuring the ring seats flush and maintains its labyrinth seal under trowel operating loads.
- Drop-In Bearing Seat Fit — Engineered to match the 6012Z bearing geometry used in CRT ride-on trowel rotor assemblies, installing directly without modification to the housing or bearing.
- Broad CRT Series Coverage — Fits CRT36 and CRT48 ride-on trowel models across the 23K, 24A, 25, 25K, 26A, and CRTv26A variants, covering both standard and high-speed configurations.
- Bearing Protection Where It Counts — Blocks concrete slurry, water, and fine abrasive debris from migrating into the bearing race — the primary cause of premature bearing failure on finishing trowels.
- Verified Genuine OEM Part — Part number 5000118807 is the authorized Wacker Neuson replacement, confirming correct application before the part ships.
A Nilos ring is a thin, press-fit labyrinth seal that mounts against the face of a shielded bearing to provide an additional barrier against contamination. On ride-on concrete trowels, the rotor assemblies operate close to wet concrete surfaces, exposing bearings to slurry, water, and abrasive particles. The Nilos ring closes the gap between the bearing shield and the housing bore, preventing that material from reaching the bearing races. When the ring is cracked, deformed, or missing entirely, contamination enters the bearing directly, leading to increased friction, heat buildup, and eventual bearing failure — which can take the rotor assembly offline mid-pour.
