S7011 ACE/HCP4ADGA Bearing Product Overview & Core Advantages
The S7011 ACE/HCP4ADGA is a high-precision double row angular contact ball bearing engineered for demanding applications. Its design excels at simultaneously handling combined radial and axial loads from both directions. Featuring a P4A super-precision tolerance and a ceramic ball construction, this bearing delivers exceptional high-speed performance, superior rigidity, and extended service life, making it ideal for high-reliability and high-accuracy machinery.
S7011 ACE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7011 | Basic bearing series and size designation (55mm bore, 90mm OD). |
| ACE | Indicates a 25° contact angle and Extra Light (A) preload. |
| HC | Refers to the Hybrid Ceramic construction (steel rings with ceramic balls). |
| P4A | Denotes a super-precision tolerance class, tighter than ABEC 7. |
| DGA | Signifies the bearing is Universal Matchable (SU) and comes as part of a matched set of 2 bearings. |
S7011 ACE/HCP4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness and can support significant combined loads (radial and bidirectional axial loads).
Exceptional High-Speed Performance: The combination of ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic cage allows for a very high limiting speed of 34,000 rpm.
Precision & Longevity: Manufactured to P4A tolerance for minimal runout and vibration. The sealed and grease-lubricated design ensures consistent performance and offers a maintenance-free operation within the specified temperature range.
S7011 ACE/HCP4ADGA Bearing Typical Application Areas
This high-performance precision bearing is ideally suited for:
- Machine Tool Spindles (high-speed milling, grinding)
- Precision Robotics and Automation Equipment
- High-Frequency Motors and Spindles
- Medical and Dental Equipment Spindles
- Aerospace Instrumentation and Control Systems
