Structural Features and Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces friction, heat generation, and wear, enabling higher limiting speeds (32,500 rpm) and extended service life compared to all-steel bearings.
High Rigidity and Load Capacity: The angular contact design with a precise 18° contact angle provides excellent resistance to combined radial and axial loads, with dynamic and static load ratings of 7312 lbf and 6862 lbf respectively.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore tolerance: -0.004mm to 0), this bearing ensures minimal vibration and superior running accuracy in high-speed applications.
Universal Matchability: As a Universal Matchable (SU) bearing, it can be paired with another identical bearing in various preload configurations without selective matching, simplifying installation and maintenance.
