The Wacker Neuson Seal Ring is a genuine OEM component designed for the BFS series walk-behind floor saws, covering a wide range of models including the BFS 935A, BFS 1335A, BFS 1345A, BFS 1350A, BFS 1318A, BFS 914AB, and BFS 940A families. Sourced directly from Wacker Neuson, this genuine OEM part is manufactured to the exact material and dimensional specifications of the original, ensuring proper sealing performance within the saw's drivetrain or cutting system. The is a direct-fit replacement that installs into the same position as the factory part, with no rework needed. If your BFS floor saw is showing signs of fluid seepage, contamination ingress, or abnormal wear near sealed interfaces, replacing the seal ring promptly helps restore proper operating condition.
Key Features
- Genuine OEM Sealing Material: — Manufactured to Wacker Neuson's original compound and hardness specifications, ensuring the correct compression and chemical resistance for floor saw operating conditions.
- Direct-Fit Replacement: — Engineered to the same dimensions as the original 5000126939, seating correctly into the existing groove or bore without modification to adjacent components.
- Broad BFS Series Coverage: — Compatible with BFS 935A, BFS 1318A, BFS 1335A, BFS 1345A, BFS 1345AB, BFS 1345ALS, BFS 1350A, BFS 1350AL, BFS 1350ALS, BFS 914AB, and BFS 940A models.
- Prevents Contamination and Fluid Loss: — A correctly seated seal ring keeps lubricants contained and blocks debris, dust, and moisture from entering sealed assemblies — critical on a floor saw operating in abrasive concrete-cutting environments.
- Fluid and Debris Ingress Protection: — Concrete dust and slurry are highly abrasive; a compromised seal ring accelerates internal wear on shafts and bearings, making timely replacement essential to maintaining drivetrain integrity.
A seal ring forms a tight interface between rotating or mating components, preventing the escape of lubricating oil or grease and blocking the entry of contaminants such as water, dust, and debris. In a walk-behind floor saw like the BFS series, the operating environment is especially harsh — fine silica dust and water slurry are constantly present during cutting. When a seal ring wears, cracks, or loses its compression, lubricants leak out and abrasive particles work their way into bearings, shafts, or gear housings, accelerating internal wear and potentially causing premature component failure. Replacing the seal ring at the first sign of seepage keeps internal assemblies protected and the saw performing as intended.
