Performance Characteristics:

  • Structural Configuration: Precision-engineered radial ball bearing featuring a thin-section geometry, optimized for applications where radial space is limited and high rotational stability for large-diameter shafts is required.
  • Protection Mechanism: Equipped with high-performance double-sided rubber contact seals (2RS) that create a high-integrity barrier against dust, moisture, and fine environmental contaminants, ensuring optimal internal lubricant retention.
  • Operational Efficiency: The optimized internal raceway geometry facilitates smooth rotational kinematics and low frictional torque, making it a reliable choice for high-speed precision equipment and automated machinery.
  • Mechanical Interface: 55 x 72 x 9 mm dimensional format manufactured to rigorous industrial tolerances to guarantee secure fitment, reduced mechanical vibration, and high rotational accuracy under radial loads.
