6313 J Deep Groove Ball Bearing (65x140x33mm) | Heavy Duty Industrial Motor & Pump Bearing | SW Precision Series
The SW 6313 J Deep Groove Ball Bearing is engineered for demanding industrial environments requiring superior performance and longevity. Featuring a robust 65 mm bore, 140 mm outer diameter, and 33 mm width, this bearing provides exceptional rigidity and reliable operation under combined heavy radial and moderate axial loads. The 'J' designation signifies a high-strength pressed steel cage, optimized for high rotational speeds (up to 4,800 rpm with grease lubrication) and resistance to high operating temperatures. Manufactured to strict ISO standards, the 6313 J utilizes premium-grade bearing steel (usually 52100 chrome steel) and precision-honed raceways to minimize friction and heat generation, delivering a dynamic load rating (Cr) exceeding 100 kN.
Selecting the SW 6313 J ensures maximum uptime and reduced maintenance costs across critical applications such as electric motors, centrifugal pumps, heavy-duty gearboxes, and industrial ventilators. Our commitment to 'SW Precision' means every bearing undergoes rigorous quality control checks for dimensional accuracy and running smoothness, guaranteeing reliable operation even in continuous-duty cycles. This bearing is a direct, high-performance replacement for comparable 6313 series bearings from any major manufacturer, offering exceptional value, long fatigue life, and the rugged dependability your machinery requires. Invest in SW quality for unmatched durability and operational efficiency.
