S7013 ACD/HCP4AQBCB Bearing Product Overview & Core Advantages
The S7013 ACD/HCP4AQBCB is a super-precision quadruplex matched bearing set designed for the most demanding high-speed and high-rigidity applications. This metric angular contact ball bearing set features a back-to-back (QBC) arrangement, enabling it to withstand combined loads—significant radial and bidirectional axial loads simultaneously. Its construction with ceramic balls and a P4A tolerance class ensures exceptional rotational accuracy, low heat generation, and extended service life, making it ideal for high-reliability machinery.
Model Code In-Depth Analysis
| Code Segment | Technical Meaning |
|---|---|
| S7013 | Basic bearing series, indicating a 65 mm bore, 100 mm OD, and 18 mm width per bearing. |
| ACD | Angular Contact Design with a 25° contact angle for optimal axial load capacity. |
| HC | Hybrid Ceramic, signifying ceramic balls for reduced friction and higher speed capability. |
| P4A | The tolerance class, denoting very high precision for running accuracy and dimensional stability. |
| QBC | Quadruplex Back-to-Back matched set. Four bearings are pre-matched for optimal load sharing and system stiffness. |
S7013 ACD/HCP4AQBCB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The quadruplex back-to-back arrangement creates an extremely rigid bearing system, capable of handling heavy combined loads and moments. The 25° contact angle is optimized for substantial axial load support in both directions.
Superior High-Speed Performance: The combination of hybrid ceramic balls (lower density, reduced centrifugal force) and a lightweight phenolic cage allows for a very high limiting speed of 31,000 rpm. This design minimizes friction and heat buildup.
Precision & Longevity: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration. The standard grease lubrication and sealed design protect against contamination, providing a long, maintenance-free operational life within its specified temperature range.
