| Suffix Code | Technical Meaning | Significance |
|---|---|---|
| ACD | Angular Contact, Double Row | Optimized for combined loads and high rigidity. |
| GB | Light Preload (Class B) | Reduces deflection and improves system stiffness for precision applications. |
| P4A | High Precision Tolerance Class | Guarantees extremely tight dimensional and running accuracy, superior to ABEC-7. |
S7016 ACDGB/P4A Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides significantly increased radial and axial stiffness compared to single row bearings, enabling stable operation under combined loads. With a 25° contact angle and robust construction, it efficiently supports substantial bidirectional axial loads.
High-Speed Performance: The phenolic resin cage is lightweight and possesses excellent sliding properties, contributing to lower friction, reduced heat generation, and a high limiting speed of 28,000 rpm. This makes it a true high-speed bearing.
Precision & Universal Matching: Manufactured to a P4A tolerance class, it ensures minimal runout and vibration. Designated as Universal Matchable (SU), these bearings can be supplied in sets of three (as specified) for pre-adjusted, interchangeable mounting, simplifying installation and ensuring optimal preload in the application.
Sealed & Lubricated for Life: As a sealed bearing, it is protected from contamination and comes pre-lubricated with grease, offering a wide temperature range from -30°C to 110°C for reliable, long-term operation with minimal maintenance.
S7016 ACDGB/P4A Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving machines, and high-frequency motors.
- Industrial Pumps & Compressors: Where high rigidity and speed are required.
- Robotics & Automation: High-accuracy rotary joints and axes.
