30311 7311E 30311JR Chrome Steel 55*120*31mm Single Row Cone and Cup Tapered Roller Bearings
The 30311, 7311E, and 30311JR tapered roller bearings are forged from high-grade chrome steel (GCr15/SAE 52100), which undergoes precision heat treatment to achieve a hardness of HRC 58-62. Engineered for robust medium-duty performance while maintaining a balanced footprint (55mm ID, 120mm OD, 31.5mm width), this material delivers exceptional wear resistance, impact tolerance, and basic corrosion protection—outperforming low-carbon steel alternatives in harsh scenarios. It resists premature wear in dusty construction machinery, rust in humid workshops, and minor chemical exposure in industrial auxiliaries, extending service life by 95-105% and slashing frequent replacement costs for equipment like heavy gearboxes or truck hubs.
