This matched set delivers exceptional high rigidity and axial load capacity in a compact design. Its key advantages include the ability to handle combined loads efficiently, superior high-speed performance enabled by a phenolic cage and ceramic balls, and a preloaded configuration for maximum operational precision and stiffness. This bearing is engineered for applications requiring the highest levels of accuracy and reliability.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| S7005 | Series designation for a 25mm bore, 47mm OD angular contact ball bearing. |
| CE | Indicates 15° contact angle. |
| HC | Signifies Hybrid Ceramic construction with ceramic balls and steel rings. |
| P4A | Denotes an ultra-high precision tolerance class (superior to ABEC 7). |
| DT | Specifies a Duplex Tandem arrangement, where two bearings are matched to carry thrust load in the same direction. |
S7005 CE/HCP4ADT Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The use of ceramic balls significantly reduces centrifugal forces, friction, and heat generation. This directly contributes to a higher limiting speed, reduced wear, and longer service life, especially in high-velocity applications.
Phenolic Resin Cage: The lightweight and robust phenolic cage ensures excellent dimensional stability and low friction at high speeds, further enhancing the bearing's high-speed capabilities.
Duplex Tandem (DT) Arrangement: This preloaded matched set provides exceptional axial stiffness and is specifically configured to handle heavy unidirectional thrust loads. The preload eliminates internal clearance, resulting in superior rotational accuracy and rigidity.
Super-Precision P4A Tolerances: Manufactured to the strictest P4A tolerance class, this bearing guarantees minimal runout and vibration, which is critical for applications demanding the highest levels of precision.
