QJ 213 N2PHAS Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry allows the bearing to handle combined radial and axial loads from both directions simultaneously with a single bearing row, offering a compact and weight-saving solution.
High Rigidity & Load Capacity: The optimized internal geometry and use of chrome steel for both rings and balls provide high rigidity, supporting substantial dynamic load ratings of 24,750 lbf and static load ratings of 25,200 lbf.
Precision Performance: Manufactured to P6 (ABEC-3) tolerance standards with precise dimensional control (bore diameter tolerance: -0.012mm to 0), ensuring high running accuracy and minimal vibration.
High-Speed Capability: The lightweight PEEK cage reduces centrifugal forces, contributing to a high limiting speed of 9,500 rpm and stable operation at high rotational velocities.
Simplified Assembly: The snap ring groove (N2) on the outer ring facilitates secure axial location and simplifies housing design and bearing installation.
Ready-to-Use Lubrication: The bearing comes pre-lubricated, ensuring immediate operation and reducing maintenance requirements.
