| ACE | 25° contact angle, phenolic cage, preloaded | Optimized for high-speed operation and rigid support |
| P4A | P4 tolerance class (ABEC-7 precision) | Ensures precise rotational accuracy and minimal runout |
S7005 ACE/P4A Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The phenolic resin cage provides excellent dimensional stability and reduced weight, contributing to lower vibration levels and enhanced high-speed capability. The P4 precision grade guarantees tight dimensional tolerances for superior running accuracy.
Optimized Load Capacity: With a 25° contact angle design, this bearing effectively handles combined radial and axial loads. The radial dynamic load rating of 1784 lbf and static load rating of 878 lbf ensure reliable performance under various loading conditions.
High-Speed Performance: The phenolic cage and optimized internal geometry enable a limiting speed of 42,000 rpm, making it suitable for demanding high-speed applications. The preloaded configuration minimizes axial play for stable operation.
Material Excellence: Manufactured from chrome steel for both rings and balls, providing excellent hardness, wear resistance, and fatigue life. The bearing comes pre-lubricated for immediate operation.
