NU 320 ECM/C3

If you are outfitting industrial machinery that regularly deals with massive radial loads and rapid rotational speeds, the NU 320 ECM/C3 single row cylindrical roller bearing is easily one of the most reliable hardware options available. Measuring 100mm on the inner bore, 215mm across the outer diameter, and 47mm wide, this heavy-duty component utilizes a precision-machined brass cage that does a brilliant job of minimizing friction and extending the unit's overall service life. A major functional perk of the NU 320 ECM/C3 lies in its smart, separable internal configuration-it pairs a completely flangeless inner ring with a double-flanged outer ring, allowing the shaft to comfortably accommodate axial displacement in both directions without tearing up the surrounding housing. Because excessive heat and thermal expansion are constant headaches in continuous-duty operations, the specialized C3 internal radial clearance built directly into the NU 320 ECM/C3 gives the rolling elements the vital breathing room they need to prevent friction lock-ups. Whether you are rebuilding a massive factory gearbox or a high-torque electric motor, dropping a fresh NU 320 ECM/C3 into the assembly ensures your equipment runs cool and steady even while pushing its demanding 3,200 RPM reference limits.

We provide sea and air freight services for large bearings, and international express shipping services for small bearings.
