7013 ACE/P4A Bearing Product Overview & Core Advantages
The 7013 ACE/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Designed to accommodate primarily axial loads in one direction and combined loads, it features a 25° contact angle for optimal performance. Manufactured to P4 (ABEC-7) tolerance class, this bearing delivers superior running accuracy, making it ideal for high-speed spindles and precision machinery where reliability and minimal runout are critical.
7013 ACE/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACE | Indicates a 25° contact angle and optimized internal design for high-speed operation and high rigidity. |
| P4A | Specifies the tolerance class P4 (ABEC-7), denoting very high dimensional and running accuracy. |
7013 ACE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row design with a 25° contact angle provides high axial rigidity and precise shaft positioning, essential for applications demanding minimal deflection.
