S7006 ACDGC/P4A Bearing Product Overview & Core Advantages
The S7006 ACDGC/P4A is a precision angular contact ball bearing designed for high-performance applications requiring exceptional rotational accuracy and rigidity. Engineered to a P4A tolerance class, this bearing is optimized to handle combined loads—simultaneous radial and axial forces—with high reliability. Its moderate preload (Class C) ensures consistent performance, minimal deflection, and smooth operation at high speeds, making it an ideal choice for demanding, precision-driven machinery.
S7006 ACDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7006 | Basic bearing series and size designation (30mm bore, 55mm OD, 13mm width). |
| ACD | Angular Contact Design with a 25° contact angle for optimal axial load capacity. |
| GC | Indicates a specific internal clearance and preload grouping for universal matching (SU). Two bearings are supplied as a matched set. |
| P4A | Denotes an ultra-precision tolerance class superior to ABEC 7, ensuring extremely tight dimensional and running accuracy. |
S7006 ACDGC/P4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with a 25° contact angle and moderate preload provides superior rigidity, effectively resisting operational deflection under combined radial and axial loads.
High-Speed Performance: The phenolic cage is lightweight and robust, contributing to lower friction and stable operation at the high limiting speed of 71,500 rpm. The standard grease lubrication is suitable for this high-speed range.
Precision & Longevity: Manufactured to P4A precision standards from high-grade chrome steel, the bearing guarantees minimal runout and consistent performance. The sealed design protects against contamination, enhancing service life in challenging environments.
