S7013 ACDGA/HCP4A Bearing Product Overview & Core Advantages
The S7013 ACDGA/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This single bearing features a 25° contact angle and is manufactured to P4A super-precision tolerance, ensuring minimal runout and superior rotational accuracy. Its core advantages include the ability to handle combined loads (radial and axial) efficiently, excellent high-speed capability facilitated by its phenolic cage and ceramic balls, and long service life due to its sealed and pre-lubricated design. This bearing is ideal for applications where high rigidity and precise positioning are critical.
S7013 ACDGA/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7013 | Basic bearing series and size designation (65mm bore, 100mm OD, 18mm width). |
| AC | Angular Contact design, optimized for combined loads. |
| D | High Ball Diameter and quantity for increased load capacity. |
| GA | Universal Matchable (SU) bearing. Can be mounted in pairs (back-to-back, face-to-face, or tandem) without selective machining to achieve preload. |
| HC | Indicates the use of Hybrid Ceramic balls (Ceramic balls with steel rings). |
| P4A | Specifies the tolerance class, which is a super-precision grade with very tight dimensional and running accuracy limits. |
S7013 ACDGA/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces friction, heat generation, and wear. This extends bearing life and allows for higher limiting speeds compared to all-steel bearings. It also provides better resistance to electrical arcing.
- Phenolic Cage: The lightweight and robust phenolic resin cage offers excellent dimensional stability at high speeds, contributing to smooth operation and reduced vibration.
- Sealed & Pre-lubricated Design: The integrated seals protect against contamination and retain the high-performance grease lubrication, making the bearing maintenance-free for its entire service life within the specified temperature range (-30°C to 110°C).
- High Rigidity and Load Capacity: The 25° contact angle and optimized internal geometry provide high rigidity, enabling the bearing to support significant combined radial and axial loads.
- Super-Precision P4A Tolerance: Manufactured to the strictest dimensional and running accuracy standards, this bearing ensures minimal vibration and superior performance in high-precision machinery.
