Why choose these tapered roller bearings over generic alternatives? Superior raceway hardness (HRC 60–63), precision-ground rollers, and optimized contact geometry deliver higher dynamic load ratings (+12% vs. P0-only equivalents) and smoother torque transmission. All units undergo 100% vibration testing and are packed in anti-rust carton-pallets compliant with ISO 8502-3.
FAQ: Are these interchangeable with SKF 30328 J2/Q or 32230 J2? Yes — identical internal geometry and tolerance stack-up. Do they meet DIN 616/ISO 355 standards? Fully compliant. What’s the max recommended speed (oil lubrication)? Up to 2,800 rpm at 140°C ambient.
