S7007 ACDGA/HCP4A Bearing Product Overview & Core Advantages
The S7007 ACDGA/HCP4A is a high-precision double row angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and reliability. This metric bearing features a universal matchable (SU) design, allowing for flexible mounting in sets of four to achieve optimal preload and system rigidity. Its core advantages include the ability to simultaneously support combined loads (radial and bidirectional axial loads), superior running accuracy from its P4A tolerance class, and high-speed capability enabled by its phenolic cage and ceramic balls. The sealed design with pre-applied grease ensures long-term, maintenance-free operation.
S7007 ACDGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7007 | Basic bearing series and size designation (35mm bore, 62mm OD, 14mm width). |
| AC | Angular Contact design with a 25° contact angle. |
| D | Double Row design for high rigidity and increased load capacity. |
| GA | Indicates the universal matchable (SU) arrangement and extra light preload (Class A). |
| HCP4A | Defines the tolerance class P4A for high running accuracy, and the bearing is sealed and pre-lubricated with grease. |
S7007 ACDGA/HCP4A 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 with high stability.
- High-Speed Performance: The combination of a lightweight phenolic cage and low-friction ceramic balls significantly reduces centrifugal forces and heat generation, allowing for a high limiting speed of 41,000 rpm.
- Precision & Accuracy: Manufactured to P4A tolerance class with tight dimensional control on the bore, outside diameter, and width, ensuring exceptional running precision for critical applications.
- Longevity & Maintenance-Free Operation: The integral seals protect against contamination, and the pre-applied grease lubrication within a temperature range of -30°C to 110°C ensures consistent performance and a long service life without re-lubrication.
