305272 DB

Design Features of 305272 DB Bearing

305272 DB 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. 305272 DB bore dia is 220 mm. Its out dia is 309.5 mm. 305272 DB width is 76 mm. This bearing is essential in applications where high radial and axial load capacity, rigidity, and reliability are required.

 

What Benefits Can 305272 DB 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 305272 DB Bearing Be Used for?

305272 DB 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.
