S7026 CD/P4A Bearing Product Overview & Core Advantages
The S7026 CD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high rigidity. Engineered to P4 (ABEC-7) tolerance class, it excels in handling combined loads, simultaneously supporting significant radial loads and axial loads in one direction. Its sealed and pre-lubricated design ensures long-term, maintenance-free operation, making it an ideal choice for high-speed, high-reliability machinery.
S7026 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| C | 15° Contact Angle | Optimized for high-speed operation and moderate axial load capacity. |
| D | High Load Capacity Internal Design | Enhanced dynamic and static load ratings. |
| P4A | P4 (ABEC-7) Tolerance Class with Specific Running Accuracy | Guarantees superior running accuracy and low vibration for precision applications. |
S7026 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The optimized internal geometry, including a 15° contact angle and high-grade chrome steel components, provides excellent resistance to deformation under combined loads. The radial dynamic load rating of 33,300 lbf and static load rating of 35,100 lbf confirm its robust performance.
- High-Speed Performance: The lightweight, durable phenolic resin cage minimizes centrifugal forces and friction, enabling a high limiting speed of 7,000 rpm. This makes it suitable for demanding high-speed spindle applications.
- Sealed & Lubricated for Life: As a sealed bearing that is pre-lubricated, it is protected from contamination and is designed for long service life without maintenance, operating reliably within a temperature range of -30°C to 110°C.
- Precision Engineering: Manufactured to P4 tolerance class with tight dimensional controls on the 130 mm bore, 200 mm outside diameter, and 33 mm width, ensuring predictable performance and ease of installation in precision assemblies.
S7026 CD/P4A Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Grinding Spindles: Applications requiring extreme rotational accuracy and rigidity.
- High-Frequency Motors: Spindles for PCB drilling and other high-RPM electric motors.
- Medical Equipment: Centrifuges and high-speed dental handpieces.
- Aerospace & Defense Systems: Gyroscopes, radar systems, and other precision instrumentation.
