Problema. Frequent bearing failures in a limestone mining conveyor (operating at 1,200 RPM, 80°C ambient).
Solução. Replaced standard 30302 bearings with 4T_30302 units. Resulted in 40% longer service life and reduced downtime.
Problema. Premature wear in commercial truck wheel hubs under 5-ton axial loads.
Solução. Installed 4T_30302 bearings with optimized preload. Achieved 18-month lifespan vs. 9-month industry average.
Desafio. Bearing replacements every 6 months in offshore wind turbines.
Resultado. 4T_30302 bearings reduced maintenance cycles to 24 months, saving €120,000/year.
Desafio. 30% failure rate in combine harvesters during peak seasons.
Resultado. Post-installation, failure rates dropped to 4%, boosting customer satisfaction.
