FAQs:
  • What's the purpose of the self-aligning function in this bearing?
    It compensates for angular misalignment (up to 2°) between the shaft and bearing housing, reducing wear caused by mounting errors or shaft deflection in operating equipment.
  • Why choose the extended inner ring (40mm) model?
    The 40mm extended inner ring provides longer axial contact with the shaft, enhancing mounting stability—especially suitable for heavy-vibration scenarios like agricultural machinery.
  • What do 'TN' and 'TN9' mean in the model number?
    Both refer to nylon cage configurations; 'TN9' is a standard suffix for self-aligning ball bearings with nylon cages, ensuring low-noise, low-friction operation.
  • What industries commonly use this 11204 bearing?
    It's widely used in electric motor rotor assemblies, centrifugal pump shaft supports, industrial fan bearing housings, textile machinery drive components, conveyor system rollers, agricultural equipment gearboxes, and general industrial machinery maintenance.
