Design Features of 3218 A Bearing

3218 A Bearing features two rows of balls, which increases the load capacity and rigidity compared to single-row bearings. The raceways in the inner and outer rings are displaced relative to each other, allowing the bearing to accommodate combined loads. 3218 A bore dia is 90 mm. Its out dia is 160 mm. 3218 A width is 52.4 mm. This bearing is essential in applications where high radial and axial load capacity, rigidity, and reliability are required.

 

What Benefits Can 3218 A Bearing Provide?

  • Enhanced Load Capacity: The double-row design significantly increases both radial and axial load-bearing capabilities compared to single-row bearings.
  • Accommodation of Bidirectional Loads: Efficiently handle axial loads in both directions, making them versatile for various applications.
  • High Rigidity and Stability: Offer increased rigidity and stability, essential for precision applications and heavy load conditions.
  • Compact Design: Provide the benefits of two single-row angular contact ball bearings in a smaller footprint, optimizing space usage.

 

What Can 3218 A Bearing Be Used for?

3218 A Bearing is widely used in applications requiring robust support for combined loads and high rigidity. Key uses include:

  • Automotive Industry: Particularly in wheel hub assemblies for improved vehicle handling and stability.
  • Industrial Machinery: In pumps, compressors, and gearboxes where higher radial and axial load support is essential.
  • Agricultural Equipment: For enhanced performance in heavy-duty farming machinery.
  • Precision Equipment: In CNC machines and precision measuring instruments.
  • Material Handling Systems: For conveyors and lifting equipment, providing stability and load capacity.
