S7007 ACE/HCP4A Bearing Product Overview & Core Advantages
The S7007 ACE/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional speed and rigidity. This single-row bearing features a 25° contact angle and is supplied with a preload, delivering superior rotational accuracy and stiffness. Its construction with ceramic balls and a phenolic cage enables outstanding high-speed performance, with a limiting speed of 36,000 rpm. Designed to handle combined radial and axial loads simultaneously, it is an ideal solution for high-reliability, precision machinery.
S7007 ACE/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| ACE | Indicates a 25° contact angle and the presence of a preload for enhanced rigidity. |
| HC | Signifies the use of Hybrid Ceramic balls (ceramic balls with steel rings), which reduce friction and heat generation. |
| P4 | Denotes a high-precision tolerance class (ABEC-7 / ISO P4), ensuring minimal runout and vibration. |
S7007 ACE/HCP4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of lightweight phenolic resin cage and low-friction ceramic balls significantly reduces centrifugal forces and operating temperature, enabling the bearing to achieve its high limiting speed of 36,000 rpm.
- Enhanced Rigidity and Accuracy: The application of a preload eliminates internal clearance, resulting in superior shaft positioning accuracy and high system stiffness, which is critical for precision applications.
- Superior Load Capacity: The 25° contact angle is optimized to efficiently support significant combined loads (radial and axial acting together).
- Long-Term Reliability: The bearing is pre-lubricated and sealed, protecting against contamination and providing maintenance-free operation within the specified temperature range of -30°C to 110°C.
S7007 ACE/HCP4A Bearing Typical Application Areas
