✨What are the Benefits of choosing 313822 bearings?

  • Extremely high load-bearing capacity: Designed to withstand extremely high radial loads, it is ideal for equipment such as rolling mills.
  • Small footprint: Provides maximum radial support within a limited space, with a compact structure.
  • Easy installation and maintenance: Employs a separable design (the inner ring with roller assembly can be separated from the outer ring), facilitating installation, disassembly, and maintenance.
  • Low frictional heat generation: Low friction between the rollers and the flanges results in low temperature rise, suitable for high-speed operation.
  • Long service life: Maintains high reliability and long service life even under harsh conditions such as high loads, high temperatures, and water erosion.
  • The 313822 Four-row cylindrical roller bearings adopts a Extremely high load-bearing capacity, strong radial rigidity, separable, and impact resistant design, with dimensions an inner diameter of 280 mm, an outer diameter of 390 mm, a width of 220 mm, featuring Four (row) construction from 3138.. (series), a clearance of C4, ensure the equipment operates more stably , and the maximum speed can reach (Limit Speed Ratings (grease) rpm:1182 Limit Speed Ratings (oil) rpm:1689)for applications Rolling mills (Metal rolling), heavy machinery, large axle systems, and construction/mining equipment.

🏭 What are the applications of the 313822 bearing?

  • Iron and Steel Metallurgy (Rolling Mill Roll Necks, Continuous Casting Machine Drive Rolls): Withstands extremely high radial loads, ensuring rolling accuracy and significantly extending bearing life in high-temperature water erosion environments.
  • Mining (Crushers, Heavy-Duty Vibrating Screens): Withstands strong impacts and dust pollution, maintaining continuous and stable operation under harsh conditions.
  • Heavy Machinery (Large Gearboxes, Rotary Kiln Support Rollers): Provides ultra-high rigidity, supporting heavy-duty rotating components and effectively reducing downtime for maintenance.
