S7026 ACD/P4A Bearing Product Overview & Core Advantages
The S7026 ACD/P4A is a precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. As a single-row bearing, it is engineered to accommodate high combined loads, primarily thrust loads in one direction, while also supporting significant radial loads. Its P4 (ABEC-7) tolerance class ensures superior running accuracy, making it ideal for high-speed spindles and other precision machinery. The bearing comes pre-lubricated and is available with a preload, contributing to its high system rigidity and immediate operational readiness.
S7026 ACD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Signifies a 25° contact angle, optimized for handling high thrust loads. |
| P4A | Indicates a P4 tolerance class (equivalent to ABEC-7), denoting very high precision for running accuracy and dimensional stability. |
S7026 ACD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The single-row design with a 25° contact angle and P4 tolerance provides excellent rotational precision and system stiffness, crucial for minimizing deflection under load.
- Superior Load Capacity: Engineered to support high combined loads, with a significant emphasis on one-directional thrust load capacity, complemented by a robust radial load rating.
- Optimized High-Speed Performance: The use of a lightweight, durable phenolic cage reduces centrifugal forces, contributing to a high limiting speed and stable operation at high RPMs.
- Enhanced Durability and Reliability: Manufactured from chrome steel for both rings and balls, ensuring high hardness and wear resistance. The bearing is pre-lubricated for long-term performance within its specified temperature range.
