Structural Features and Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls (Si3N4) significantly reduces friction, minimizes heat buildup, and enables higher operating speeds. This construction also provides electrical insulation and enhanced durability.
High-Speed Phenolic Cage: The phenolic resin cage offers excellent dimensional stability at high speeds and temperatures, contributing to the bearing's limiting speed of 22,000 rpm.
Precision and Rigidity: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration. The 15° contact angle and moderate preload provide high system rigidity and precise axial positioning.
Universal Matchability (SU): As a universal matchable bearing, the two bearings in the set can be arranged in various configurations (back-to-back, face-to-face, or tandem) to suit specific application requirements for moment load capacity and stiffness.
