Introduction
An engineering company in Mechelen, Belgium, was designing automatic vegetable handling equipment for greenhouses. They needed bearings that could survive difficult, dirty conditions: wet peat, roots, and constant moisture that would clog normal bearings.
The Challenge
Greenhouse lettuce handling creates a uniquely challenging environment. Wet peat from growing media constantly drops onto conveyors. Root masses and plant debris create contamination. High humidity and water spray add moisture. Normal bearings become clogged quickly, requiring frequent cleaning or replacement. The engineering company needed truly maintenance-free operation.
The Solution
After thorough evaluation, 1-inch diameter Extreme Bearing units were selected in January 2016. The centrifugal seal design actively repels contamination rather than simply blocking it. Moisture and peat particles are thrown off by shaft rotation. AISI 316 stainless steel resists constant moisture and soil chemicals.
Results
The two-year testing period (2014-2016) proved the bearings' capabilities. Despite constant exposure to wet peat, roots, and moisture, the bearings maintained perfect operation. No clogging, no contamination ingress, no maintenance required. The engineering company now specifies Extreme Bearings as standard equipment.
Key Takeaways
- Two-year testing validates performance in contaminated environments
- Centrifugal seal design actively repels agricultural debris
- Moisture resistance prevents corrosion in greenhouse humidity
- Maintenance-free operation reduces total cost of ownership
