S7011 ACE/HCP4ADT Bearing Product Overview & Core Advantages
The S7011 ACE/HCP4ADT is a high-precision duplex tandem angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This matched bearing set features a P4A tolerance class for superior running accuracy and is preloaded for immediate high-rigidity operation. Its ceramic balls and phenolic cage contribute to lower friction, higher limiting speeds, and extended service life, making it ideal for machine tool spindles and other high-speed, high-precision machinery.
S7011 ACE/HCP4ADT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| ACE | 25° contact angle, standard preload | Optimized for combined radial and axial loads |
| HC | Hybrid Ceramic (Silicon Nitride balls) | Higher speed capability, reduced heat generation, longer life |
| P4A | ABEC 7 / ISO P4A tolerance class | Exceptional running accuracy for high-precision applications |
| DT | Duplex Tandem arrangement | Increased axial load capacity in one direction |
S7011 ACE/HCP4ADT Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex tandem arrangement and 25° contact angle provide high system rigidity and enable the bearing to handle significant combined radial and axial loads efficiently.
High-Speed Performance: The combination of hybrid ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic resin cage allows for a high limiting speed of 34,000 rpm, making it a true high-speed bearing.
Precision & Longevity: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration. The sealed design with pre-applied grease protects against contamination and provides reliable, maintenance-free operation within a wide temperature range.
