NU 314 ECM/C3

NU 314 ECM/C3 cylindrical roller bearings are optimized for high radial load capacity and medium speed applications in industrial machinery, including electric motors, gearboxes and material handling systems. The "ECM" suffix indicates enhanced internal geometry that reduces stress concentrations, while the C3 radial internal clearance accommodates thermal expansion in high temperature environments (up to 120°C) or in applications with dynamic shaft misalignment. The bearings have a dynamic load rating of 325 kN and a maximum operating speed of 6,000 rpm, and feature an integrated stamped steel cage to guide the rollers and maintain stability during sudden load changes, such as in conveyor drives or printing press cylinders. The bearings are pre-lubricated with lithium-based grease and support maintenance intervals of up to 8,000 hours under clean conditions. NU 314 ECM/C3 bearings are typically used in pump shafts, compressor components and agricultural machinery because they can accommodate high shock loads and meet the shaft dimensions specified in ISO 15:2011 (70 mm ID, 150 mm OD, 35 mm width). Optional sealing solutions such as RUBY or Nilos rings increase their resistance to contamination in harsh environments such as mining or food processing plants.
