SELECTION CONTEXT
Match the bearing
to its duty.
NU224 belongs to the cylindrical roller bearings family. Its reference envelope is 120 mm bore, 215 mm outside diameter and 40 mm overall width or height.
Cylindrical rollers provide radial load capacity. NU, NJ and other ring arrangements differ in axial location and displacement capability.
For a manufacturing enquiry, provide the complete designation and operating conditions. Matching the dimensional envelope alone does not confirm interchangeability or equivalent performance.
Is the same size a direct replacement?
No. Matching 120 × 215 × 40 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
