Wacker Neuson 5000401621 Disc Spring

The Wacker Neuson Disc Spring is a genuine OEM component designed for BFS1214, BFSX1214, MFS14, MFSX14, BFS 614B, and BFS 614AB series floor saws. As a direct factory part, it meets the exact material and dimensional standards specified for these machines. This disc spring is compatible across multiple configuration variants within the BFS and MFS floor saw families, making it a reliable choice for technicians servicing a wide range of Wacker Neuson cutting equipment.

Key Features

• Genuine OEM Spring Temper and Geometry — Manufactured to the precise load-deflection curve required for correct clamping and tensioning performance in Wacker Neuson floor saws.
• Drop-In Installation — Engineered to the exact inner diameter, outer diameter, and cone height of the original, seating correctly without rework or shimming.
• Broad Floor Saw Compatibility — Fits BFS1214, BFSX1214, MFS14, MFSX14, BFS 614B, and BFS 614AB series, covering a wide span of Wacker Neuson floor saw production runs.
• Consistent Clamping Force — A correctly rated disc spring maintains the designed preload in the assembly; a fatigued or undersized spring leads to inconsistent blade clamping, vibration, and accelerated wear on mating components.
• Sourced Direct from Wacker Neuson — Part number 5000401621 is an authorized OEM part, ensuring the material grade and heat treatment match the original component replaced during service.

A disc spring — also called a Belleville washer — is a conical washer designed to exert a controlled, consistent axial load when compressed. In floor saw applications, disc springs are commonly used to maintain precise preload on blade arbor assemblies, clutch packs, or tensioning mechanisms, ensuring components stay firmly seated under the vibration and load cycles of concrete and asphalt cutting. When a disc spring fatigues, cracks, or loses its cone height, the clamping force it provides drops off, which can result in blade slippage, uneven cuts, increased vibration, and premature wear on surrounding hardware. Replacing a worn disc spring with the correct OEM part restores the designed load characteristics and protects the integrity of the wider assembly.
