S7016 ACD/P4AQGB Bearing Product Overview & Core Advantages
The S7016 ACD/P4AQGB is a precision double-row angular contact ball bearing designed for applications requiring exceptional rigidity and accuracy. Engineered to simultaneously handle combined radial and bidirectional axial loads, this bearing features a universal matchable (SU) design, allowing for flexible mounting arrangements in preloaded sets. Its P4A tolerance class ensures ultra-precise running accuracy, making it ideal for high-speed, high-reliability machinery where performance is critical.
S7016 ACD/P4AQGB Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | 25° contact angle design optimized for high axial load capacity |
| P4A | Ultra-precision tolerance class exceeding ABEC 7 standards |
| QGB | Special grease lubrication for high-speed operation |
S7016 ACD/P4AQGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double-row angular contact design provides superior stiffness, enabling stable operation under heavy combined loads. With a 25° contact angle and optimized internal geometry, this bearing efficiently manages both radial loads (37,125 lbf dynamic) and bidirectional axial forces.
High-Speed Performance: The phenolic cage material ensures minimal friction and excellent performance at limiting speeds up to 28,000 rpm. Combined with special high-speed grease, this bearing maintains stable operation in demanding high-velocity applications.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore: -0.004mm to 0), this bearing delivers exceptional running accuracy and minimal vibration for precision applications.
Universal Matching Capability: The Universal Matchable (SU) design allows bearings to be mounted in any combination while maintaining preload consistency, simplifying installation and ensuring optimal performance in multi-bearing arrangements.
