7001 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7001 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and high-speed performance. Manufactured to P4A tolerance class, this bearing delivers superior running accuracy and rotational precision. Its universal matchable (SU) design allows for flexible mounting arrangements in pairs, enabling it to accommodate combined loads—significant radial and axial loads in both directions. Preloaded to extra light (Class A), it ensures minimal deflection and high system rigidity, making it ideal for high-precision, high-reliability machinery.
Model Code Breakdown
| 7001 | Basic designation: Metric series, 12mm bore, 28mm OD |
| CD | Contact angle of 15° and optimized internal design |
| P4A | High precision tolerance class for exceptional running accuracy |
| DGA | Universal matchable bearing supplied in a matched set of 2 |
7001 CD/P4ADGA Bearing Structural Features & Performance Benefits
High Precision & Rigidity: The P4A tolerance class ensures minimal runout and vibration, while the 15° contact angle and extra light preload provide high system stiffness and precise rotational characteristics.
Optimized High-Speed Performance: The phenolic cage and precision-ground chrome steel components enable stable operation at limiting speeds up to 110,000 rpm, making it an excellent high-speed bearing solution.
Superior Load Capacity: With a dynamic load rating of 1638 lbf and static load rating of 855 lbf, this bearing effectively handles combined radial and axial loads in demanding applications.
Universal Matching Capability: The SU designation allows bearings to be mounted in various configurations (back-to-back, face-to-face, or tandem) without selective assembly, simplifying installation and maintenance.
