Multiquip 1157A Bearing Insert

The Multiquip 1157A Bearing Insert is a genuine OEM component designed for JWN24HTCSL ride-on power trowels and J Series walk-behind power trowels. Sourced directly from Multiquip, this bearing insert meets the original engineering specifications for these machines, giving you confidence that the part will seat and perform exactly as intended. Whether you are servicing a ride-on unit or a walk-behind trowel, verifying the 1157A part number against your machine's parts list before ordering is always recommended to confirm fitment.

Key Features

• Genuine OEM Precision — Manufactured to the original tolerancing specifications required for smooth, low-friction rotation in trowel blade assemblies, ensuring the bearing insert seats without play or misalignment.
• Direct Drop-In Replacement — Engineered to match the original mounting interface on compatible Multiquip trowels, allowing straightforward installation without machining or modification.
• Broad Trowel Compatibility — Fits JWN24HTCSL ride-on power trowels and J Series walk-behind power trowels, covering both commercial finishing and international walk-behind applications.
• Blade-System Integrity — A correctly functioning bearing insert maintains proper blade pitch movement and rotation. A worn or failed insert can cause blade wobble, uneven float patterns, and accelerated wear on surrounding components.
• Verified Multiquip Part Number — The 1157A designation is the authoritative Multiquip OEM reference — use it to cross-check your machine's service manual and parts diagram before ordering.

A bearing insert is a self-contained bearing unit pressed or seated into a housing to support a rotating shaft or spindle. In a power trowel, bearing inserts are critical to the blade pitch and rotation mechanism — they allow the trowel arms and blade holders to turn smoothly under the significant load and vibration generated during concrete finishing. When a bearing insert wears out, operators typically notice increased vibration, noise from the blade assembly, or inconsistent blade pitch response, all of which compromise the quality of the finished concrete surface and can accelerate damage to adjoining hardware.
