S7006 ACD/P4ADGA Bearing Product Overview & Core Advantages
The S7006 ACD/P4ADGA is a metric double row angular contact ball bearing designed for exceptional performance in demanding applications. Engineered with an Extra Light (Class A) preload and manufactured to P4A tolerance class, this bearing delivers superior running accuracy and high rigidity. Its double row design enables it to support combined radial and axial loads from both directions simultaneously, making it an ideal, compact solution for high-precision machinery requiring high reliability and dimensional stability.
S7006 ACD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact, Double Row design. |
| P4A | High precision tolerance class, exceeding ABEC 7 standards, for minimal runout and vibration. |
| DGA | Indicates specific internal design and Universal Matchable (SU) pairing for precise preload control when mounted in pairs. |
S7006 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact structure and 25° contact angle provide high rigidity, enabling the bearing to handle significant combined loads and bidirectional axial thrust.
- High-Speed Performance: The phenolic resin cage ensures low friction and excellent dimensional stability at high speeds, contributing to a high limiting speed of 71,500 rpm.
- Precision & Stability: Manufactured to P4A tolerance class with tight dimensional tolerances on the bore, outside diameter, and width, guaranteeing precise shaft positioning and smooth operation.
- Sealed & Lubricated for Life: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is maintenance-free within its specified temperature range of -30°C to 110°C.
S7006 ACD/P4ADGA Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications including:
- Machine Tool Spindles
- High-frequency Precision Spindles
- High-Speed Motors and Pumps
- Precision Grinding Equipment
- Other machinery requiring high rigidity and superior rotational accuracy.
