The Wacker Neuson Tapered Roller Bearing Cup is a genuine OEM component designed for the CRT36 and CRT48 series ride-on concrete power trowels. This cup is the outer race of the tapered roller bearing assembly, engineered to Wacker Neuson's exact tolerances to maintain proper load distribution and rotor alignment across a wide range of trowel configurations. Fitment spans the full CRT36 and CRT48 lineups, including standard, high-speed, power steer, dual-fuel, electronic steering, and EU-spec variants. As a genuine OEM part, the is manufactured to the same specifications as the original component installed at the factory.
Key Features
- OEM-Grade Bearing Geometry — Manufactured to the exact taper angle and surface finish specification required for correct load transfer between the cup and roller cone assembly.
- Direct Drop-In Replacement — Matches the original bore diameter and seating depth, so the cup presses into the housing without modification to the carrier or adjacent components.
- Broad CRT Series Fitment — Compatible with a wide range of CRT36 and CRT48 ride-on concrete trowel models, covering 36-inch and 48-inch rotor configurations in standard, high-speed, power steer, dual-fuel, and electronic steering variants.
- Maintains Rotor Stability Under Load — A correctly seated bearing cup keeps the trowel rotor running true, preserving a smooth, consistent finish pass. A worn or pitted cup causes rotor wobble, uneven blade contact, and accelerated bearing failure.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 5000115849 carries full OEM traceability and is the correct service replacement for all listed CRT models.
The tapered roller bearing cup is the hardened outer race that works together with the tapered roller cone to support radial and axial loads on the trowel's rotor shaft. It provides the precision running surface the rollers travel against, keeping the rotor centered and stable during finishing operations. When the cup becomes worn, pitted, or spalled, bearing noise increases, rotor runout worsens, and the surrounding housing can sustain damage — making timely replacement essential to maintaining finish quality and preventing more extensive drivetrain repairs.
