S7013 CE/P4A Bearing Product Overview & Core Advantages
The S7013 CE/P4A is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered to the P4 (ABEC-7) tolerance class, it delivers superior running precision. Its key advantage lies in its ability to accommodate combined loads, simultaneously handling significant radial loads and axial loads in one direction. The bearing is preloaded and comes sealed and lubricated from the factory, ensuring immediate, maintenance-free operation and a long service life in high-speed and high-rigidity environments.

| S | Stainless Steel bearing ring |
| 7013 | Standard bearing series and size designation (65mm bore, 100mm OD, 18mm width) |
| CE | Specific internal design and contact angle (15°) |
| P4A | High precision tolerance class (ABEC-7), with specific running accuracy requirements |
S7013 CE/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: Manufactured to P4 tolerance with a 15° contact angle, this bearing provides excellent rotational accuracy and system stiffness, minimizing deflection under load.
- Superior Load Capacity: The optimized internal geometry and use of 25 high-grade chrome steel balls enable high radial dynamic (4568 lbf) and static (3510 lbf) load ratings for its compact bearing dimensions.
- High-Speed Capability: The lightweight phenolic cage ensures stable operation and contributes to a high limiting speed of 19,000 rpm, making it an ideal high-speed bearing.
- Ready-to-Use & Durable: The sealed design with factory-applied lubrication protects against contamination and retains grease, offering a maintenance-free solution within the specified temperature range of -30° to 110°C.
