Key Features

• Genuine OEM Bearing Precision — Manufactured to the original Timken #M11910 cup specification, ensuring correct taper angle and surface finish for proper load distribution across the bearing assembly.
• Drop-In Replacement — Matches the original bore diameter and seating depth for a straightforward press-fit installation without machining or shimming.
• Broad Trowel Compatibility — Fits B46, BS46, JS36, J36-M30, BH, BS90C, CA4HC/CA5BC, JH, and JS60C series Multiquip and Whiteman power trowels in both walk-behind and ride-on configurations.
• Sustained Blade Rotation Integrity — A properly seated cup bearing keeps the trowel spider and blade assembly running true; a worn cup allows play that causes uneven blade pitch and accelerated wear across drivetrain components.
• Correct Load Rating for Trowel Duty — The Timken M11910 cup is rated for the radial and thrust loads generated during concrete finishing cycles, supporting consistent blade pressure across the slab surface.

A bearing cup — also called a bearing race — is the outer ring of a tapered roller bearing assembly. It provides the hardened, precision-ground surface that the tapered rollers travel against, transferring rotational load from the inner cone to the surrounding housing. In a power trowel, this bearing assembly supports the rotating gearbox or spider shaft that drives the finishing blades, absorbing both radial and axial forces generated during operation. When the cup wears, becomes pitted, or loses its surface finish, the bearing develops slop and heat, which can lead to vibration, inconsistent blade pitch, and eventual gearbox damage if left unaddressed.
