Introduction
At the Prins & Dingemanse mussel processing factory in Yerseke, Netherlands, Extreme Bearings with distinctive blue end covers were installed on a conveyor start point. The location represents worst-case conditions: continuous saltwater exposure, shell fragments everywhere, and heavy loading.
The Challenge
The conveyor start point handles the initial mussel flow from washing operations. Conditions are severe: heavily loaded bearings support the weight of mussels plus conveyor components, constant drench of seawater runs down from above, cracked mussel shells and sand fall continuously onto and around the bearings. Normal bearings in this location failed every few months, requiring emergency shutdowns for replacement.
The Solution
Extreme Bearing units chosen specifically for this critical location. The blue end covers became a visible indicator of the Extreme Bearing installation. Complete AISI 316 stainless steel construction resists the saltwater. Centrifugal seal design actively prevents shell fragments and sand from entering despite continuous bombardment.
Results
After one year of continuous operation, the factory conducted a planned inspection. Technicians opened the bearing end covers expecting to find at least some contamination or wear. Instead, they discovered: absolutely no contamination inside the bearing housing, zero wear on any components, seals still perfect and effective, all lubricant clean and in good condition. The bearings were simply resealed with fresh grease and returned to service. They continued operating for another full year before the next scheduled inspection.
Key Takeaways
- One-year inspection validated zero contamination ingress
- Maintenance-free operation confirmed in worst-case conditions
- Seal technology proven effective against shell fragments and sand
- AISI 316 construction showed no corrosion after year in saltwater
