[6] Supply Tractor Tail Wheel Bearing 30204 Tapered Roller Bearing
The Tapered Roller Bearing 30204 is designed for high radial and axial load capacities, ideal for heavy-duty applications. Key parameters include.
Parameter | 30204 | Competitor Model X |
---|---|---|
Inner Diameter (mm) | 20 | 20 |
Outer Diameter (mm) | 47 | 47 |
Dynamic Load Rating (kN) | 43.6 | 39.8 |
Material | Chrome Steel (SAE 52100) | Carbon Steel |
Advantages. Superior heat resistance (up to 120°C), 30% longer service life than industry average, and ISO 9001-certified manufacturing.
The 30204 bearing is critical in.
Step 1. Clean housing and shaft surfaces to ISO 4406:2021 standards.
Step 2. Apply lithium-based grease (NLGI Grade 2) to bearing surfaces.
Step 3. Use hydraulic press for mounting - maximum 5 kN axial force.
Maintenance. Relubricate every 500 operating hours or 3 months.
Case A. Wheat Combine Harvester Gearbox
Problem. Frequent bearing failures during harvest season (40% downtime).
Solution. 30204 bearings increased service intervals from 200 to 1,200 hours.
