The Wacker Neuson Cup Spring is a genuine OEM component designed for the PIR 55 series pneumatic internal concrete vibrators. As a factory-sourced part, it is manufactured to the same specifications as the original component installed at the time of production, ensuring a direct, hassle-free replacement. This Cup Spring is confirmed to fit the PIR 55 () and PIR 55 () pneumatic internal vibrator models.
Key Features
- Genuine OEM Spring Integrity — Manufactured to the original load and deflection characteristics required for correct vibrator head operation, maintaining consistent spring tension over repeated use cycles.
- Direct Drop-In Replacement — Engineered to seat and locate exactly as the original Cup Spring, fitting directly into the vibrator head assembly without modification.
- Confirmed PIR 55 Fitment — Verified for Wacker Neuson PIR 55 pneumatic internal concrete vibrators across both listed configurations.
- Sustained Vibration Output — A correctly tensioned Cup Spring helps maintain the consistent eccentric motion that keeps concrete flowing and consolidating evenly; a fatigued or broken spring can cause erratic or lost vibration output.
- OEM Part Number Assurance — Ordering by Wacker Neuson part number 5000068288 confirms you receive the exact component specified for your machine, eliminating guesswork during service.
The Cup Spring is a small but critical component within the vibrator head of a pneumatic internal concrete vibrator. It provides the spring force that works in conjunction with the eccentric mechanism to generate and regulate the vibrating motion transmitted through the vibrator head and poker. When this spring fatigues, deforms, or breaks, the vibrator may produce weak, irregular, or no vibration at all, compromising concrete consolidation and leaving voids or poor surface finish in the finished slab or pour.
