Design Features of 1204 ETN9 Bearing

1204 ETN9 Bearing is a type of rolling-element bearing uniquely designed to tolerate misalignment of the shaft with respect to the housing. It has two rows of balls and a common spherical raceway in the outer ring, allowing the bearing to be self-aligning. 1204 ETN9 bore dia is 20 mm. Its out dia is 47 mm. Its width is 14 mm. 1204 ETN9 Bearing is versatile and adaptive, ensuring smooth operation even when not perfectly aligned. Its unique design helps prevent stresses on the bearing, resulting in a longer operational life.

 

What Benefits Can 1204 ETN9 Bearing Provide?

  • Misalignment Adaptability: These bearings efficiently handle both static and dynamic misalignment, resembling the self-aligning capabilities of spherical roller bearings.
  • High-Speed Efficiency: With reduced friction compared to other bearings, they remain cool, even at elevated speeds.
  • Longevity and Low Maintenance: Their ability to run cooler means longer bearing life and fewer maintenance breaks.
  • Optimized for Light Loads: They operate exceptionally well, even under minimal load conditions.
  • Noise and Vibration Reduction: Ideal for applications like fans, these bearings help in decreasing noise and vibration levels.

 

What Can 1204 ETN9 Bearing Be Used for?

1204 ETN9 Bearing is suitable for applications where misalignment can arise from errors in mounting or from shaft deflection.

  • Automotive: Used in power steering systems, drive shafts, and steering column joints, where angular misalignments are common.
  • Agricultural: Essential in farm equipment like tractors and harvesters, where uneven terrains can cause shaft misalignment.
  • Textile: Deployed in spinning and weaving machines where smooth, consistent rotation is crucial.
  • Conveyor Systems: Useful in belt systems to maintain consistent belt tension and alignment, especially in long-distance conveyors.
  • Mining and Double Row: Used in crushers, vibrating screens, and heavy-duty machinery that undergo rigorous operation and potential shaft deflections.
