The Wacker Neuson Cup Bearing is a genuine OEM component designed for CRT36 and CRT46 series ride-on concrete trowels, including the CRT36ASO, CRT36ASN, and CRT46ASO models. As a factory-sourced part, it meets the original design specifications for these machines and installs directly in place of the worn or failed original. Sourcing the correct OEM bearing for ride-on trowel applications ensures the rotor assembly maintains proper alignment and smooth rotational movement throughout operation.
Key Features
- Genuine OEM Bearing Spec — Manufactured to the original load rating and dimensional tolerance required by the CRT trowel rotor assembly, so bearing clearance and seating depth match the design intent exactly.
- Direct-Fit Replacement — Seats into the original bearing housing on CRT36 and CRT46 trowels without reworking the bore or modifying surrounding components.
- Confirmed Fitment — Compatible with CRT36ASO, CRT36ASN, and CRT46ASO ride-on concrete trowels.
- Smooth Rotor Operation — A correctly seated cup bearing supports consistent blade pitch control and uniform float pressure across the trowel deck; a worn bearing introduces rotor wobble and uneven concrete finishing.
- Backed by Wacker Neuson OEM Sourcing — Supplied as a genuine Wacker Neuson part, ensuring the component history and material grade match what came off the assembly line.
A cup bearing is the outer ring of a tapered roller bearing assembly, providing the hardened raceway surface against which the tapered rollers travel. In a ride-on concrete trowel, bearings in the rotor and drive system must handle continuous radial and axial loads during finishing passes. When a cup bearing wears, develops pitting, or loses its press fit in the housing, it causes increased vibration, uneven blade loading, and accelerated wear on surrounding components — all of which degrade the quality of the finished concrete surface and can lead to more extensive drivetrain repairs if left unaddressed.
