[9] SKF 30302J2 Metric Single Row Taper Roller Bearing 15x42x14.25mm
The Metric Taper Roller Bearing 4T_30302 (15×42×14.25mm) is designed for high radial and axial load capacity in industrial applications. Below are its key specifications:
| Parameter | 4T_30302 | Standard 30302 |
|---|---|---|
| Inner Diameter (d) | 15 mm | 15 mm |
| Outer Diameter (D) | 42 mm | 42 mm |
| Width (T) | 14.25 mm | 14.25 mm |
| Dynamic Load Rating (C) | 34.5 kN | 30.2 kN |
| Static Load Rating (C0) | 30.8 kN | 27.5 kN |
Advantages: Higher load ratings, precision grinding for reduced friction, and ISO 355:2007 compliance.
This bearing is ideal for:
Problem: Frequent bearing failures in a limestone mining conveyor (operating at 1,200 RPM, 80°C ambient).
Solution: Replaced standard 30302 bearings with 4T_30302 units. Resulted in 40% longer service life and reduced downtime.
Problem: Premature wear in commercial truck wheel hubs under 5-ton axial loads.
Solution: Installed 4T_30302 bearings with optimized preload. Achieved 18-month lifespan vs. 9-month industry average.
Challenge: Bearing replacements every 6 months in offshore wind turbines.
Outcome: 4T_30302 bearings reduced maintenance cycles to 24 months, saving €120,000/year.
Challenge: 30% failure rate in combine harvesters during peak seasons.
Outcome: Post-installation, failure rates dropped to 4%, boosting customer satisfaction.
