1. Complete size lineup：Full metric series covering 30305 up to 30328, wider cross‑section and larger rolling elements than 302 series, stronger load‑bearing capacityMade-in-Ch...。

2. High combined load performance：Single‑row tapered roller structure, withstand heavy radial load plus one‑way axial load, excellent impact resistance for tough working conditions。

3. Separable assembly design：Cone assembly and cup are separable, easy installation, disassembly and field maintenance, normally used in paired arrangement。

4. Reliable material & stable running：Adopt high‑quality bearing steel, fine heat‑treatment process, low friction, stable rotation and extended service life under continuous heavy‑load operation。

5. Broad industry application：Fit for heavy‑duty gearboxes, truck wheel hubs, construction machinery, mining equipment, agricultural machinery, metric standard for global interchangeability。
