Wacker Neuson 5000206941 Lock Washer

The Wacker Neuson Lock Washer is a genuine OEM component designed for the BFS series floor saws, including the BFS735, BFS940, BFS1345, and BFS1350 models. Sourced directly from Wacker Neuson, this lock washer meets the exact specifications of the original part, ensuring correct fitment without guesswork. It is also compatible with a wide range of BFS saw variants including AB, ABZ, BZ, W, and Wz configurations, as well as the AS50e and AS60e models.

Key Features

• Genuine OEM Locking Integrity — Manufactured to Wacker Neuson's original torque-retention specification, ensuring the washer delivers the same clamping force and anti-loosening performance as the part it replaces.
• Direct Drop-In Replacement — Matches the original hole diameter, outer dimensions, and spring profile for straightforward installation with no reworking of fastener assemblies.
• Broad BFS Series Compatibility — Verified to fit BFS735, BFS940, BFS1345, and BFS1350 floor saws across multiple build variants, including AB, W, ABZ, BZ, and Wz configurations, plus AS50e and AS60e models.
• Prevents Fastener Loosening Under Vibration — Floor saws generate significant vibration during cutting operations; a correctly functioning lock washer keeps fastened joints secure and prevents hardware migration that can lead to component damage.
• Genuine Part Assurance — Carrying OEM part number 5000206941, this washer is traceable to Wacker Neuson's authorized parts supply, so you know exactly what you are installing.

A lock washer is a small but critical fastening component that sits beneath a nut or bolt head to resist loosening caused by vibration, dynamic loads, or thermal cycling. In floor saw applications — where the machine is subjected to constant blade-induced vibration during concrete and asphalt cutting — lock washers play an important role in keeping bolted assemblies tight and structurally sound. When a lock washer wears flat, deforms, or is missing altogether, the fastener it supports can gradually back out, leading to misalignment, component wear, or unexpected hardware failure during operation.
