7013 CD/P4ADFC Bearing Product Overview & Core Advantages
The 7013 CD/P4ADFC is a precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This duplex bearing set features a Face-to-Face (DF) arrangement and comes pre-lubricated, offering superior performance in handling combined radial and axial loads. Manufactured to P4A tolerance class, it ensures minimal runout and stable operation, making it ideal for high-precision, high-reliability machinery where moderate preload (Class C) is specified for optimal stiffness.

| Code Segment | Technical Meaning |
|---|---|
| 7013 | Basic bearing designation (65mm bore, 100mm OD, 36mm width) |
| C | 15° contact angle, optimized for combined loads |
| D | Duplex Face-to-Face (DF) matched arrangement |
| P4A | High precision tolerance class (exceeds ABEC 7) |
| DFC | Specific internal design for moderate preload (Class C) |
7013 CD/P4ADFC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex DF arrangement creates a rigid bearing system capable of withstanding significant combined radial and axial loads from both directions. The 15° contact angle is engineered for optimal load distribution.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional control (bore/OD tolerance: -0.004mm to 0), this bearing ensures minimal vibration and exceptional running accuracy for high-speed applications up to 24,000 rpm.
Advanced Materials: The phenolic cage provides excellent strength-to-weight ratio and smooth operation at high speeds, while chrome steel rings and balls ensure durability and long service life.
Ready-to-Install: Supplied as a pre-lubricated, matched set of 2 bearings, this configuration eliminates complex mounting procedures and ensures consistent preload and performance right out of the package.
