The Wacker Neuson Cup Bearing is a genuine OEM component designed for the CRT36ASO, CRT36ASN, and CRT46ASO ride-on concrete trowels. As a direct OEM replacement, this bearing is manufactured to the exact tolerances required by the CRT series, ensuring correct seating and load distribution within the assembly. Wacker Neuson genuine OEM parts are produced to the same standards as the original components installed at the factory, making the a reliable choice when restoring your ride-on trowel to full working condition. Confirmed fitment covers the CRT36ASO overlapping, CRT36ASN non-overlapping, and CRT46ASO models.
Key Features
- Precision Tapered Fit — Manufactured to exact dimensional tolerances for correct cup seating and consistent load transfer within the bearing assembly.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this is the same cup bearing originally installed on CRT36 and CRT46 ride-on trowels.
- Verified CRT Series Compatibility — Fits CRT36ASO (overlapping), CRT36ASN (non-overlapping), and CRT46ASO ride-on concrete trowel models.
- Maintains Smooth Rotation Under Load — A correctly functioning cup bearing supports the tapered roller assembly and prevents binding, wobble, or uneven wear in the drivetrain.
- Direct Drop-In Replacement — Matches the original mounting dimensions and cup profile, allowing straightforward installation without machining or adaptation.
A cup bearing — also called a bearing cup or outer race — is the outer ring of a tapered roller bearing assembly. It provides the hardened raceway surface against which the tapered rollers travel, transmitting radial and axial loads from rotating components to the machine's housing or frame. On a ride-on concrete trowel like the CRT36 and CRT46 series, these bearings support the drivetrain and rotor assemblies that keep the finishing heads spinning at the correct speed and angle. When a cup bearing becomes worn, pitted, or damaged, it causes increased vibration, noise, and heat buildup, which can accelerate wear on surrounding components and lead to broader drivetrain damage if not addressed promptly.
