Multiquip 21047 Bearing Kit

The Multiquip 21047 Bearing Kit is a genuine OEM replacement designed for Whiteman and Multiquip walk-behind power trowel models including BH11C, BH90C, BS90C, J36, JH55C, JH90C, B46, CA4HC, and the JA, BA, and CA series, among others. As a factory-sourced kit, it delivers the correct bearing specifications to maintain proper rotor function and consistent blade pitch control across compatible models. DHS Equipment supplies this part direct, so you can be confident you are ordering the right kit for your machine.

Key Features

• Genuine OEM Bearing Tolerances — Sourced directly from Multiquip, this kit meets the original bearing grade and dimensional tolerances required for consistent rotor operation in walk-behind trowel gearboxes.
• Complete Kit Format — Includes all bearings needed for the service interval in a single kit, so technicians can complete the job without sourcing individual components separately.
• Broad Trowel Family Coverage — Fits an extensive range of Whiteman and Multiquip walk-behind power trowels across the BH, BS, JH, J36, B46, CA, JA, BA, and PRO series.
• Restores Smooth Blade Rotation — Worn or failed trowel bearings cause vibration, uneven blade pitch, and accelerated gear wear. This kit brings rotor bearing performance back to spec, restoring a consistent finish pass.
• Drop-In Replacement — Engineered to match original bearing seats and housings in compatible trowel models, allowing straightforward installation without machining or custom fitting.

The bearings in a walk-behind power trowel support the rotor shaft and allow the spider assembly to spin freely while transmitting drive force to the finishing blades. Over time, bearing wear causes shaft play, vibration, and inconsistent blade pitch — all of which compromise the quality of the concrete finish and accelerate stress on surrounding components. Replacing worn bearings with a correctly spec'd kit like the Multiquip 21047 restores stable, low-friction rotation and protects the gearbox from secondary damage caused by a loose or seized bearing.
