Structural Features and Performance Benefits
High Precision Construction: Manufactured to P6 tolerance class (equivalent to ABEC-3), this bearing ensures minimal runout and vibration for precision applications. The 40° contact angle provides superior axial load capacity while maintaining excellent radial load performance.
Optimized Cage Design: The glass fiber reinforced nylon cage (PH designation) offers excellent performance at high speeds, reducing friction and allowing for higher limiting speeds compared to metallic cages. This design also provides better lubrication retention and quieter operation.
Superior Load Capacity: With a dynamic load rating of 5962 lbf and static load rating of 3442 lbf, this bearing delivers reliable performance under demanding operating conditions. The optimized internal geometry ensures even stress distribution and extended service life.
High-Speed Capability: Featuring a limiting speed of 15,000 rpm, this bearing is engineered for high-speed applications. The combination of precision manufacturing, optimized internal clearance, and advanced cage design contributes to its exceptional high-speed performance.
