S7014 ACB/P4A Bearing Product Overview & Core Advantages
The S7014 ACB/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This single-row bearing features a 25° contact angle and is supplied with a preload, enabling it to handle combined radial and axial loads simultaneously with high stability. Manufactured to the exacting P4 (ABEC-7) tolerance class, it is ideally suited for high-speed spindles and other high-precision machinery where minimal runout and superior performance are critical.
S7014 ACB/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7014 | Basic bearing series and size designation (70mm Bore, 110mm OD, 20mm Width). |
| ACB | Indicates a 25° contact angle and a specific internal design optimized for high rigidity and speed. |
| P4A | Denotes the P4 (ABEC-7) tolerance class, ensuring extremely tight dimensional and running accuracy for precision applications. |
S7014 ACB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The 25° contact angle and applied preload provide superior system stiffness, minimizing deflection under load and ensuring precise shaft positioning, which is critical for machining accuracy.
- Optimized Load Capacity: Engineered to support significant combined radial and axial loads, with a dynamic load rating of 4095 lbf and a static load rating of 3510 lbf.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, contributing to a high limiting speed of 15,000 rpm. The bearing is pre-lubricated for immediate operation.
- Sealed & Protected: The sealed design effectively retains lubricant and excludes contaminants, enhancing bearing service life and reliability in demanding environments.
- Premium Materials: Constructed from chrome steel for rings and balls, ensuring high durability, wear resistance, and consistent performance within a temperature range of -30°C to 110°C.
S7014 ACB/P4A Bearing Typical Application Areas
This precision angular contact ball bearing is ideally deployed in:
