Multiquip 20576-501 Drum Bearing Assembly

The Multiquip 20576-501 is a genuine OEM Drum Bearing Assembly designed for Multiquip masonry saw models MS20H, MS20E, MS30H, and MS30E. Sourced directly from Multiquip, this assembly delivers the same precision tolerancing and dimensional accuracy as the original factory component. It is a direct-replacement part that installs into the blade drum housing exactly as the original, ensuring correct blade alignment and smooth rotational operation. Contractors and operators can count on this assembly to restore their masonry saw to full cutting performance without guesswork.

Key Features

• Precision-Toleranced Bearing Assembly — Manufactured to OEM specification for exact dimensional fit within the drum housing, maintaining proper blade concentricity and smooth rotation under load.
• Direct Drum Housing Fit — Designed to seat into the drum assembly of MS20H, MS20E, MS30H, and MS30E saws without modification, aligning with existing mounting points and hardware.
• Broad MS-Series Compatibility — Covers both Honda-powered (MS20H, MS30H) and electric-motor-powered (MS20E, MS30E) Multiquip masonry saw variants in a single part number.
• Cutting Accuracy Restored — A worn or failed drum bearing causes blade wobble, vibration, and imprecise cuts; replacing it with this assembly brings blade tracking back to spec and protects the blade arbor.
• Genuine OEM Confidence — As an authentic Multiquip replacement part, the part meets the same material and load-rating standards as the component it replaces, supporting consistent performance over extended service intervals.

The drum bearing assembly supports the rotating blade drum, allowing it to spin freely and concentrically on the saw's arbor shaft while absorbing the radial and axial loads generated during masonry cutting. When this bearing wears or fails, operators typically notice increased vibration, audible grinding, or a noticeable drift in cut accuracy — all signs that the drum is no longer tracking true. Replacing a worn drum bearing assembly promptly protects surrounding components such as the arbor, blade flanges, and housing from secondary damage caused by an out-of-balance drum.
