The Wacker Neuson Nilos Ring is a genuine OEM sealing ring designed for CRT36 and CRT48 series ride-on concrete power trowels. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, this part is manufactured to the same specification as the original component installed at the factory. Fitment spans a wide range of CRT36 and CRT48 models, including standard, high-speed, power steer, dual-fuel, and electronic steering variants. Verifying your machine's model number before ordering ensures a correct, hassle-free installation.
Key Features
- OEM Sealing Integrity — Manufactured to the original material and dimensional specification, ensuring the Nilos Ring seats and seals correctly against the bearing race without deformation or gap.
- Drop-In Bearing Seal Replacement — Designed to install directly into the original bearing seat position on CRT36 and CRT48 rotor assemblies with no reworking of the housing required.
- Broad CRT Series Coverage — Fits a wide range of CRT36 and CRT48 configurations, including standard, high-speed, power steer, dual-fuel, and electronic steering models across multiple production runs.
- Protects Bearing from Concrete Contamination — A correctly seated Nilos Ring shields the adjacent bearing from slurry, moisture, and abrasive concrete paste — the leading causes of premature bearing failure in ride-on trowels.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component under part number 5000157004, backed by Wacker Neuson's parts program for traceability and quality assurance.
A Nilos Ring is a precision-stamped metal sealing ring that fits directly against the face of a bearing, acting as a labyrinth-style shield between the bearing and the surrounding environment. In ride-on concrete trowels, the rotor shaft bearings operate in close proximity to wet concrete, slurry, and fine aggregate — conditions that are highly abrasive and destructive to unprotected bearings. The Nilos Ring deflects this contamination away from the bearing's rolling elements and grease, extending bearing service life significantly. When this ring is worn, cracked, or missing, abrasive material works into the bearing, accelerating wear and leading to rough rotor operation, vibration, and eventual bearing seizure.
