Multiquip 1157 Bearing Insert

The Multiquip 1157 Bearing Insert is a genuine OEM component designed for Whiteman and international ride-on and walk-behind power trowel models including the LD60, LD6, JWN24HTCSL, HTN series, JTO series, B46, J-Series, and B-Series machines. As a direct OEM replacement, the 1157 is manufactured to the same tolerances as the original part, ensuring correct seating and consistent load distribution within the trowel's rotor assembly. This bearing insert is verified to fit an extensive range of Multiquip Whiteman power trowels, giving contractors confidence that they are installing the right part the first time. DHS Equipment stocks genuine Multiquip parts so you can get back to finishing concrete without unnecessary delays.

Key Features

• Genuine OEM Tolerancing — Manufactured to Multiquip's original dimensional specifications, ensuring correct radial load capacity and shaft alignment specific to power trowel rotor assemblies.
• Drop-In Installation — Engineered to seat directly into the original bearing pocket without machining or shimming, maintaining the rotor's designed rotational geometry.
• Broad Trowel Compatibility — Fits a wide range of Whiteman and international power trowel models including the LD60, LD6, JWN24HTCSL, HTN series, JTO series, J-Series, B-Series, and BS/JS walk-behind models.
• Smooth Blade Rotation — A correctly functioning bearing insert keeps trowel blades spinning true and evenly, delivering consistent float and finish passes across the concrete slab.
• Prevents Rotor Wear Progression — A worn or failed bearing insert accelerates shaft and housing wear; replacing it promptly protects the surrounding components from secondary damage.

A bearing insert supports and positions a rotating shaft within a housing, absorbing radial loads while allowing the shaft to spin freely with minimal friction. In a power trowel, the bearing insert is a critical element of the rotor assembly — it keeps the blade spider centered and rotating smoothly so that each trowel blade maintains even contact pressure across the concrete surface. When this insert wears, develops play, or fails, the rotor can wobble or drag, producing uneven finishing marks, accelerating blade wear, and putting stress on the gearbox and drive components above it.
