S7015 ACD/P4A Bearing Product Overview & Core Advantages
The S7015 ACD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Manufactured to P4 (ABEC-7) tolerance class, this bearing is preloaded and features a phenolic cage, enabling it to handle combined radial and axial loads simultaneously. Its compact design and high rigidity make it an ideal choice for high-precision spindles and other machinery where reliability and minimal runout are critical.
S7015 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7015 | Series designation for a high-precision angular contact ball bearing. |
| ACD | Indicates a 25° contact angle and that the bearing is supplied as a universal design (can be paired in various configurations). |
| P4A | Specifies the P4 (ABEC-7) tolerance class and that the bearing is preloaded to a specific level (Light preload). |
S7015 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single, matched arrangement with a 25° contact angle and factory-applied preload ensures high system stiffness and precise shaft positioning, critical for minimizing deflection under load.
- Superior High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, enabling stable operation at the high limiting speed of 10,000 rpm. This makes it a true high-speed bearing.
- Optimized Load Capacity: Engineered to support significant combined loads, with a dynamic load rating of 11,115 lbf and a static load rating of 10,462 lbf.
- Sealed & Lubricated for Life: As a sealed bearing, it is pre-lubricated and protected from contamination, offering a maintenance-free solution within its specified temperature range of -30°C to 110°C.
S7015 ACD/P4A Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles (e.g., CNC milling, grinding)
- High-Frequency Motors
- Precision Robotics and Automation Equipment
- Medical and Dental Equipment Spindles
- Aerospace Instrumentation
