Premium taper roller bearings designed for radial/axial load support in heavy-duty machinery. Features optimised contact angles and advanced heat treatment for enhanced durability.
| Model | d (mm) | D (mm) | T (mm) | Dynamic Load (kN) | Static Load (kN) |
|---|---|---|---|---|---|
| 32309 | 45 | 100 | 38.25 | 215 | 305 |
| T5gd0705 | 70 | 110 | 42.5 | 335 | 480 |
Comparative analysis shows 15-20% higher load capacity in T5gd070 series compared to standard 323XX series.
Optimal preload: 0.05-0.10mm for automotive applications. Use induction heating below 120°C for interference fits.
