7013 CE/P4AQBCC Bearing Product Overview & Core Advantages
The 7013 CE/P4AQBCC is a precision angular contact ball bearing configured in a Quadruplex Back-to-Back (QBC) matched set. Engineered for applications demanding exceptional rotational accuracy and rigidity, this bearing is designed to handle combined loads (radial and axial) simultaneously. Its P4A tolerance class ensures superior running accuracy, making it ideal for high-speed, high-precision machinery where stability and reliability are paramount. The pre-lubricated and moderate preload (Class C) simplifies installation and guarantees immediate operational readiness.
7013 CE/P4AQBCC Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 7013 | Basic bearing designation indicating a metric series angular contact ball bearing with a 65 mm bore, 100 mm OD, and 72 mm width. |
| CE | Indicates a moderate preload (Class C) applied to the bearing. |
| P4A | Specifies the tolerance class, denoting very high precision levels for dimensional and running accuracy. |
| QBCC | Denotes the bearing is supplied as part of a Quadruplex Back-to-Back (QBC) matched set of 4 bearings. |
7013 CE/P4AQBCC Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The Quadruplex Back-to-Back (QBC) arrangement creates an extremely rigid bearing system capable of supporting heavy combined loads and moment loads. The 15° contact angle is optimized for sustaining significant axial loads in both directions.
- Precision & High-Speed Performance: Manufactured to P4A tolerance class for minimal runout and vibration. The phenolic cage and optimized internal geometry contribute to stable operation at high speeds, with a limiting speed of 31,000 rpm.
- Optimized Internal Geometry: Features 25 high-precision chrome steel balls with a diameter of 8.731 mm, ensuring smooth operation and high dynamic load rating of 12,150 lbf.
- Ready-to-Install: The bearings are pre-lubricated and feature an open seal type, making them suitable for integrated centralized lubrication systems. The moderate preload eliminates the need for complex adjustment during installation.
7013 CE/P4AQBCC Bearing Typical Application Areas
This high-precision, high-rigidity bearing set is ideally suited for demanding applications such as:
- Machine Tool Spindles (e.g., high-speed milling and grinding spindles)
- Precision Gearboxes and Robotic Drives
- High-Frequency Motors and Spindles
- Medical Equipment (e.g., high-speed dental handpieces, imaging scanners)
- Aerospace Actuation Systems and Test & Measurement Equipment
