21309K

Design Features of 21309K Bearing

21309K Bearing features two rows of spherical rollers, enhancing load-carrying capacity and stability while accommodating misalignment between the shaft and housing. 21309K outer dia is 100 mm. Its bore dia is 45 mm. Its optimized roller geometry, durable materials, and effective lubrication options make it ideal for demanding applications in industries such as mining and heavy machinery. 

 

What Benefits Can 21309K Bearing Provide?

  • High Load Capacity: It can support higher radial and axial loads due to its double row design, making it suitable for heavy-duty applications.
  • Self-Alignment: The spherical design allows it to accommodate misalignment, reducing stress on the bearing and extending its lifespan.
  • Enhanced Stability: Its robust construction provides improved rigidity and stability, which is crucial in applications requiring precise load distribution.
  • Reduced Maintenance: The effective lubrication options and durable materials minimize wear and the need for frequent maintenance, leading to reduced downtime.
  • Smooth Operation: Optimized roller geometry decreases friction and enhances performance, resulting in smoother operation and lower noise levels.

 

What Can 21309K Bearing Be Used for?

  • Heavy Machinery: Commonly found in construction and mining equipment, where it can handle high radial loads and misalignment.
  • Industrial Gearboxes: Suitable for use in gearboxes, providing support for high loads and ensuring smooth operation.
  • Wind Turbines: Utilized in the rotor assembly, as it can accommodate both radial and axial loads while compensating for misalignment.
  • Material Handling Equipment: Used in cranes, conveyors, and hoists, where durability and load-bearing capacity are essential.
  • Pulp and Paper Mills: Commonly employed in rollers and presses due to their ability to withstand heavy loads and harsh operating conditions.
