S71913 ACE/HCP4ADGA Bearing Product Overview & Core Advantages
The S71913 ACE/HCP4ADGA is a high-precision double row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and reliability. This P4A tolerance class bearing features a 25° contact angle and is designed to accommodate combined radial and axial loads simultaneously. Its compact design, utilizing ceramic balls and a phenolic cage, delivers superior high-speed performance and high rigidity, making it ideal for precision spindles and other high-performance machinery.
S71913 ACE/HCP4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACE | Indicates a 25° contact angle and Extra light (A) preload. |
| HC | Refers to the Hybrid Ceramic construction, featuring steel rings and ceramic balls for reduced friction and higher speed capability. |
| P4A | Denotes a high-precision tolerance class with very tight running accuracy. |
| DGA | Signifies the bearing is universally matchable (SU), allowing two bearings to be mounted in any combination (back-to-back, face-to-face, or tandem) to optimize load handling. |
S71913 ACE/HCP4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior radial and axial stiffness, enabling the bearing to handle significant combined loads from multiple directions with high stability.
- Exceptional High-Speed Performance: The combination of lightweight phenolic resin cage and low-density ceramic balls reduces centrifugal forces, allowing for a high limiting speed of 31,000 rpm.
- Precision & Longevity: Manufactured to P4A tolerance standards, this bearing ensures minimal runout and vibration. The sealed construction with pre-lubricated grease protects against contamination and provides a long service life within a temperature range of -30°C to 110°C.
- Universal Matchability: As a Universal Matchable (SU) bearing supplied in a set of 2, it offers flexible mounting configurations to precisely manage preload and system rigidity.
S71913 ACE/HCP4ADGA Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications where precision, speed, and reliability are paramount. Key industries and equipment include:
- Machine Tool Spindles
- High-Frequency Machining Centers
- Precision Grinding Spindles
- High-Speed Robotics
- Medical and Dental Equipment
