7013 ACD/P4ADBG400 Bearing Product Overview & Core Advantages
The 7013 ACD/P4ADBG400 is a precision angular contact ball bearing supplied as a pre-loaded duplex pair in a back-to-back (DB) arrangement. Engineered for applications demanding exceptional rotational accuracy and rigidity, this P4A tolerance class bearing is designed to simultaneously handle high combined loads (radial and axial) from both directions. Its matched set configuration provides superior system stability, making it an ideal choice for high-precision, high-reliability machinery.
7013 ACD/P4ADBG400 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7013 | Basic bearing series and size designation (65mm bore, 100mm OD). |
| AC | Angular Contact design with a 25° contact angle. |
| D | Duplex (two bearings supplied as a set). |
| P4A | High precision tolerance class, exceeding ABEC 7 standards. |
| DB | Back-to-Back mounting arrangement. |
| 400 | Specific preload level applied to the duplex set. |
7013 ACD/P4ADBG400 Bearing Structural Features & Performance Benefits
- Superior Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a wide, rigid support system that effectively resists overturning moments and can accommodate high combined radial and axial loads from both directions.
- High-Speed Capability: The lightweight and robust phenolic resin cage ensures stable operation and reduced centrifugal forces, contributing to the high limiting speed of 31,000 rpm.
- Precision Performance: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring minimal runout and precise shaft positioning.
- Optimized Internal Geometry: Features a 25° contact angle and 20 high-grade chrome steel balls, balancing axial and radial load capacity for demanding applications.
- Pre-Lubricated & Ready-to-Install: The bearing is factory lubricated, simplifying installation and providing immediate operational readiness.
7013 ACD/P4ADBG400 Bearing Typical Application Areas
This bearing is specifically designed for high-performance applications, including:
- Machine Tool Spindles (milling, grinding, turning centers)
- High-frequency Spindle Motors
- Precision Gearboxes and Transmission Systems
- Industrial Pumps and Compressors
- Robotic Arm Joints and Precision Rotary Axes
