High-performance tapered roller bearings designed for wheel parts and heavy-duty machinery applications. Optimized to handle combined radial and axial loads with precision engineering for extended service life. axial loads with precision engineering for extended service life.
[6] Introduction to Bearing Designators
Tapered roller bearings from the KHRD series are engineered for heavy-duty applications requiring high radial and axial load capacity. Below are key specifications for popular models.
Model | Inner Diameter (mm) | Outer Diameter (mm) | Width (mm) | Dynamic Load Rating (kN) | Static Load Rating (kN) |
---|---|---|---|---|---|
460/453X | 45 | 100 | 32 | 245 | 320 |
535/532X | 60 | 120 | 44 | 380 | 495 |
45280/45220 | 80 | 140 | 35 | 410 | 550 |
59175/59412 | 85 | 150 | 40 | 480 | 620 |
