S71907 CE/P4ADGA Bearing Product Overview & Core Advantages
The S71907 CE/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. As a universal matchable (SU) bearing supplied in a pre-configured pair, it excels at handling combined loads—simultaneously supporting significant radial loads and axial loads in both directions. Its P4A tolerance class ensures ultra-precise running accuracy, while the extra light preload (Class A) minimizes friction and heat generation, making it an ideal solution for high-speed spindles and other precision machinery where high rigidity and rotational stability are paramount.
S71907 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| CE | Indicates a universal matchable (SU) bearing designed to be paired in any combination (face-to-face, back-to-back) without loss of preload, offering flexible mounting configurations. |
| P4A | Denotes an ultra-precision tolerance class with enhanced running accuracy and dimensional stability, exceeding ABEC 7 standards. |
| DGA | Signifies that the bearing is sealed and pre-lubricated with high-performance grease, providing long-term lubrication and protection from contamination. |
S71907 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design and 15° contact angle provide superior high rigidity and enable the bearing to handle substantial combined radial and axial loads from both directions simultaneously. This is further enhanced when mounted as a pre-loaded pair.
Precision & High-Speed Performance: The phenolic resin cage offers excellent dimensional stability with low weight, contributing to smooth operation at the limiting speed of 56,000 rpm. The P4A tolerance class and extra light preload ensure minimal vibration and heat buildup, which is critical for high-speed applications.
Durability & Maintenance-Free Operation: Constructed from chrome steel for both rings and balls, the bearing ensures high durability and wear resistance. The integral seals and pre-applied grease lubrication create a sealed, maintenance-free system that operates reliably within a temperature range of -30°C to 110°C.
