The Wacker Neuson Tapered Roller Bearing Cup is a genuine OEM component designed for CRT36 and CRT48 series ride-on concrete trowels. This is a direct OEM replacement sourced through the Wacker Neuson parts program, meaning it meets the exact material and dimensional standards of the original bearing cup 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. When your trowel's bearing assembly needs service, part number is the correct OEM cup to restore it.
Key Features
- Hardened Raceway Surface — The cup is manufactured to the correct taper angle and surface hardness required to support the tapered roller bearing load under the continuous rotational demands of a ride-on trowel drivetrain.
- Drop-In OEM Replacement — Matches the original bore diameter and seat geometry of the CRT36 and CRT48 bearing housing, seating securely without reworking or shimming the housing.
- Broad CRT Series Coverage — Confirmed fitment across CRT36-23K, CRT36-24A, CRT36-25, CRT36-26A, CRT48-25K, CRT48-31V, CRT48-33K, CRT48-34V, CRT48-35L, CRT48-35V, CRT48-37V, and CRT48-57K model families, including standard, high-speed, power steer, dual-fuel, and EU variants.
- Restored Load Distribution — A correctly fitted bearing cup keeps radial and axial loads evenly distributed across the roller set, preventing rotor shaft deflection that can lead to uneven trowel blade pressure and poor finish quality.
- Genuine Wacker Neuson OEM Part — Supplied as an authentic Wacker Neuson component, ensuring dimensional and metallurgical conformance with the original specification rather than an approximation.
The tapered roller bearing cup — also called the outer race — is the hardened ring that sits in the bearing housing and forms the outer load-bearing surface against which the tapered rollers travel. In a ride-on trowel, this bearing assembly supports the rotor shaft and absorbs both radial loads from the rotating rotor blades and axial thrust loads generated during troweling operations. When the cup develops pitting, spalling, or wear grooves from contamination or inadequate lubrication, the rollers no longer track smoothly, leading to increased vibration, heat buildup, accelerated bearing failure, and ultimately shaft damage if left unaddressed. Replacing the cup — paired with its matched cone — restores the bearing assembly to proper operating condition and protects the surrounding housing from further wear.
