Product Description

22326 Bearing Spherical Roller – Engineered for Heavy Loads & Extreme Temperatures

When your machinery operates under crushing loads or scorching temperatures, the 22326 bearing delivers unmatched reliability. Designed for heavy industrial applications like rolling mills, mining crushers, and port cranes, this self-aligning roller bearing combines a robust brass cage, high-purity steel, and precision grinding to handle dynamic loads exceeding 800kN. With a temperature resistance of up to 150°C, it’s built to endure the harshest conditions while maintaining P6-grade accuracy.

Core Advantages

  • Durability: Vacuum-degassed chromium steel and double-row roller design achieve a 50,000-hour lifespan.
  • Precision: Every bearing undergoes noise inspection (<35dB) and load validation to guarantee a 99.9% defect-free rate.
  • Agile Delivery: Standard models ship in 48 hours; custom bearing variants up to φ3000mm delivered in 15–20 days.

Industry-Proven Applications

  • Metallurgy: 22326 bearing units use heat-stable cages to maintain structural integrity in rolling mills under 400kN shock loads.
  • Mining: Reinforced cages and precision rollers survive 500TPH crusher vibrations.
  • Wind Energy: High-precision bearing performance ensures stable gearbox operation with noise control under 35dB.
