Multiquip 20474 Cone Bearing Timken M86647

The Multiquip 20474 is a genuine OEM Cone Bearing Timken M86647 designed for Whiteman and Multiquip walk-behind power trowel series, including BH11C, BH90C, BS90C, JH55C, JH90C, B46, B46S90, CA4HC, J36, JA-Series, BA-Series, and HPHA/HPLA-Series models. As a genuine OEM component, this Timken-specified tapered roller bearing cone delivers the manufacturer-correct fit and load rating your trowel was built around. DHS Equipment supplies this part direct, so you can trust you are receiving the exact replacement specified for your machine.

Key Features

• Timken-Specified Tapered Roller Design — The M86647 cone geometry provides the precise taper angle and roller path needed to handle both radial and axial loads at the trowel's blade hub or gearbox, matching the original bearing specification exactly.
• Genuine OEM Quality — Supplied as an authorized Multiquip OEM replacement, this bearing meets the same load rating, case-hardening depth, and surface-finish standards as the part installed at the factory.
• Direct-Fit Replacement — Seats into the same bearing bore and pairs with the same cup as the original, allowing straightforward installation without machining or shimming.
• Broad Walk-Behind Trowel Compatibility — Confirmed fitment across BH, BS, JH, J36, B46, CA, CA4HC, JA, BA, HPHA, HPLA, and PRO series walk-behind trowels, covering a wide range of Whiteman and Multiquip float equipment.
• Smooth Blade Rotation Under Load — A correctly seated cone bearing allows the trowel's rotor or gearbox shaft to spin freely under blade pressure; a worn or pitted cone causes vibration, heat buildup, and premature shaft wear that can sideline the machine mid-pour.

A tapered roller bearing cone works together with a matched cup (race) to support rotating shafts under combined radial and thrust loads inside walk-behind trowel gearboxes and blade hubs. The cone's angled rollers distribute force evenly across the raceway, keeping blade rotation smooth and shaft alignment true even under the sustained downward pressure of finishing work. When a cone bearing begins to wear, symptoms include abnormal vibration at the trowel head, increased blade chatter, and audible grinding — all of which indicate that the bearing is no longer controlling shaft movement correctly and that replacement is needed before further damage occurs to adjacent components.
