Multiquip 20475 Bearing Cup Timken M86610

The Multiquip 20475 is a genuine OEM Bearing Cup Timken M86610 designed for a wide range of Whiteman and Multiquip walk-behind power trowels, including J36, B46, CA, JA, BA, and HDA series machines. As a factory-sourced component, this bearing cup is manufactured to the exact dimensional and material tolerances required for proper function in the trowel's rotor and gearbox assemblies. Verified fitment spans an extensive range of models including PRO36, PRO46, JS36, BS46, CA4HC, CA4HM, HPHA36, HPHA46, and more — making 20475 a high-utility stocking part for trowel service and repair operations. Order with confidence knowing this is the same part supplied through Multiquip's authorized parts network.

Key Features

• Precision Tapered Bearing Race: — The Timken M86610 cup is a tapered roller bearing race engineered to exact dimensional tolerances, ensuring correct load distribution and smooth rotational contact against the mating cone.
• Genuine OEM Sourcing: — Supplied as a genuine Multiquip OEM component, this bearing cup meets the original design specification for the trowel's rotating assembly — no risk of dimensional mismatch or premature wear from undersized aftermarket substitutes.
• Broad Walk-Behind Trowel Compatibility: — Fits J36, JA, B46, BA, CA, PRO36, PRO46, HPHA, HPLA, JS, BS, and M30 series walk-behind trowels across both Whiteman and Multiquip branded lineups.
• Maintains Rotor Stability and Blade Geometry: — A correctly seated bearing cup keeps the rotor shaft aligned and stable under load, preserving consistent blade pitch and preventing vibration that degrades finish quality on fresh concrete.
• Drop-In Service Part: — Pressed into the bearing housing using standard tooling, the M86610 cup installs the same way as the original — compatible with the existing cone and housing bore dimensions across all listed trowel models.

A bearing cup — also called a bearing race — is the outer ring component of a tapered roller bearing assembly. It works together with the bearing cone to support radial and axial loads on a rotating shaft. In a walk-behind trowel, the bearing cup is seated in the gearbox or rotor hub housing and guides the roller elements as the shaft spins under the load of the trowel blades pressing against the concrete surface. When the cup wears, becomes pitted, or loses its surface finish, it causes uneven roller contact, increased heat, and eventual bearing failure — which can lead to shaft wobble, inconsistent blade pitch, and costly gearbox damage if left unaddressed.
