Wacker Neuson 5000020321 Shim Ring 20 X 28 X 1

The Wacker Neuson is a genuine OEM Shim Ring 20 X 28 X 1 designed for the BFS 80 and BFS 100 gasoline floor saws. As a direct factory replacement, this shim ring delivers the exact dimensional tolerancing required to maintain correct axial spacing and alignment within the saw assembly. Sourced directly from Wacker Neuson, part ensures the fit and geometry match original build specifications for both the BFS 80 (Ø 350) and BFS 100 (Ø 450) floor saw models.

Key Features

• Exact OEM Dimensional Tolerancing — Manufactured to the precise 20 x 28 x 1 mm specification, ensuring correct axial load distribution and component spacing without guesswork.
• Direct Drop-In Replacement — Matches the original shim ring profile exactly, seating cleanly into the existing assembly without shimming, filing, or fitment adjustment.
• Confirmed Fitment for BFS Floor Saws — Verified for the BFS 80 gasoline floor saw (Ø 350) and the BFS 100 gasoline floor saw (Ø 450), covering both common blade diameter configurations.
• Maintains Blade Shaft Alignment — A correctly dimensioned shim ring keeps the blade shaft running true; a worn or undersized shim can introduce runout, accelerate bearing wear, and compromise cut quality.
• Genuine Wacker Neuson OEM Part — Supplied under part number 5000020321, this is an authentic Wacker Neuson component backed by the manufacturer's part accuracy standards.

A shim ring is a precision-thickness spacer used to set and maintain the correct axial clearance between rotating or sliding components within a mechanical assembly. In a gasoline floor saw like the BFS 80 and BFS 100, the shim ring controls the positional relationship of the blade shaft and its associated components, preventing unwanted lateral movement that could affect cutting accuracy or place undue stress on bearings and seals. When a shim ring wears thin or is damaged, it can allow play to develop in the shaft assembly, leading to vibration, uneven blade wear, and premature failure of surrounding parts.
