S7013 ACB/P4A Bearing Product Overview & Core Advantages
The S7013 ACB/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered as a single-row bearing with a 25° contact angle and P4 (ABEC-7) tolerance class, it excels at handling combined radial and axial loads simultaneously. Its preload availability ensures high system rigidity and precise rotational accuracy, making it an ideal choice for high-speed spindles and other high-precision machinery.
S7013 ACB/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S7013 ACB/P4A is decoded as follows:
- S: Denotes a bearing with a super-precision tolerance class.
- 7013: Standard size designation (65mm bore, 100mm OD, 18mm width).
- ACB: Signifies Angular Contact Bearing with a 25° contact angle.
- P4A: Indicates a P4 (ABEC-7) tolerance class with specific internal clearance and geometry optimizations for precision applications.
S7013 ACB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The 25° contact angle and availability of preload provide superior axial rigidity and minimize deflection under load, ensuring exceptional running accuracy.
