Key Features
- Genuine OEM Spring Tension Integrity — Manufactured to the original spring load and dimensional spec, maintaining the correct clamping force within the assembly.
- Direct Drop-In Replacement — Engineered to seat and torque exactly as the original, with no fitting adjustments needed during installation.
- Confirmed ST-2020B Fitment — Verified compatibility with the Multiquip ST-2020B swing tube concrete pump series.
- Preserves Joint Fastening Performance — A worn or fatigued spring washer loses its ability to resist loosening under vibration; replacing it with this part restores that resistance and keeps fastened connections secure during pump operation.
- Authorized Multiquip OEM Part — Sourced directly through the Multiquip OEM supply chain, confirming this is not a generic substitute but a part built specifically for this application.
A spring washer functions as a locking element in bolted and fastened assemblies, using its compressed spring tension to resist vibration-induced loosening over time. In a concrete pump like the ST-2020B, where mechanical vibration and hydraulic pressure cycles are constant during operation, maintaining proper fastener tension is critical to keeping the machine structurally sound and leak-free. When a spring washer flattens, cracks, or loses its temper, fasteners can back out — leading to joint failure, fluid leaks, or structural misalignment that interrupts operation.
