SELECTION CONTEXT
Match the bearing
to its duty.
NJ207 belongs to the cylindrical roller bearings family. Its reference envelope is 35 mm bore, 72 mm outside diameter and 17 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 35 × 72 × 17 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
