Multiquip 20465 Bearing Cone Timken LM11949

The Multiquip 20465 is a genuine OEM Bearing Cone Timken LM11949 designed for a wide range of Whiteman and Multiquip walk-behind power trowels, including J36, JA, B46, BA, CA, BH, BS, and PRO series machines. As a genuine OEM component, part 20465 is sourced to the exact specification required for proper blade assembly and rotor hub function on these trowels. Confirmed fitment spans models such as BH11C, BH90C, BS90C, JH55C, JH90C, PRO36, PRO46, B46, J36, CA4HC, HPHA46411H, HPLA46411H, and many additional series variants. When replacing a worn or damaged cone bearing, using the correct Timken LM11949 specification ensures the rotor assembly seats and loads properly without shimming or adaptation.

Key Features

• Genuine OEM Timken Specification — Manufactured to the LM11949 Timken cone bearing standard, delivering the correct taper angle, bore dimension, and load rating required for trowel rotor and blade hub assemblies.
• Direct Drop-In Replacement — Installs directly into the existing bearing cup on compatible walk-behind trowel models without machining or re-sizing the housing.
• Broad Trowel Series Fitment — Confirmed for J36, JA, B46, BA, CA, BH, BS, PRO36, PRO46, HPHA, HPLA, and SCT series walk-behind trowels across Whiteman, Multiquip, and International lineups.
• Smooth Rotor Rotation Under Load — A correctly seated cone bearing allows the trowel rotor to spin freely and evenly under finishing pressure; a worn bearing causes wobble, uneven blade pitch, and accelerated wear on surrounding components.
• Tapered Roller Design for Radial and Axial Loads — The tapered roller geometry handles the combined radial and thrust loads generated during power trowel finishing operations, resisting the side forces that flat bearings cannot manage as effectively.

A cone bearing is the inner race and roller assembly of a tapered roller bearing set, working together with a matched outer cup to support rotating shafts under both radial and axial load. In a walk-behind power trowel, this bearing sits within the rotor or blade hub assembly and carries the load generated as the trowel blades press against and finish a concrete slab. When the cone bearing wears, the rotor develops play, blade pitch becomes inconsistent, and the finishing quality of the slab surface deteriorates — often followed by damage to the surrounding bearing housing if left unaddressed. Replacing the bearing at the first sign of roughness or looseness protects the rotor hub and restores smooth, controlled blade operation.
