S7013 ACD/P4ATGB Bearing Product Overview & Core Advantages
The S7013 ACD/P4ATGB is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Operating under P4A tolerance class, this bearing excels in handling combined radial and axial loads simultaneously. Its universal matchable (SU) design allows for flexible mounting arrangements in sets, while the light preload (Class B) ensures optimal stiffness and minimal deflection under operational stresses. The combination of chrome steel components and phenolic cage contributes to its high-speed capability and durability, making it ideal for precision machinery.

| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| ACD | Angular Contact Design with 25° contact angle | Optimized for combined load capacity and axial rigidity |
| P4A | High precision tolerance class | Superior running accuracy and minimal vibration |
| TGB | Sealed construction with grease lubrication | Contamination protection and maintenance-free operation |
S7013 ACD/P4ATGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with 25° contact angle and dual-row ball complement provides exceptional stiffness, enabling the bearing to handle significant combined loads (radial dynamic load rating: 19,170 lbf, static: 23,850 lbf) while maintaining precision alignment.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional controls (bore/OD tolerance: -0.004mm to 0), this bearing ensures minimal runout and vibration for high-precision applications.
High-Speed Capability: The phenolic cage and optimized grease lubrication allow for limiting speeds up to 31,000 rpm, making it suitable for demanding rotational applications.
Maintenance-Free Operation: The sealed construction with factory-applied grease provides long-term lubrication and protection against contaminants across a temperature range of -30°C to 110°C.
