7005 CD/P4ADGA Bearing Product Overview & Core Advantages
The 7005 CD/P4ADGA is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and high-speed performance. Manufactured to P4A tolerance class, it delivers superior dimensional stability and running precision. Its universal matchable (SU) design allows for flexible mounting in various preload configurations, enabling optimal system rigidity. This bearing is pre-lubricated and features an open design, making it ideal for high-speed spindles and other precision machinery where controlled lubrication is applied.
7005 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7005 | Basic bearing series, indicating a 25mm bore, 47mm OD, and 24mm width. |
| C | 15° contact angle, optimized for high-speed applications and combined loads. |
| D | Universal Matchable (SU) design. Two bearings can be paired in a matched arrangement. |
| P4A | High-precision tolerance class exceeding ABEC 7, ensuring minimal runout and vibration. |
| DGA | Manufacturer's internal code for specific preload (Extra light / Class A) and grouping. |
7005 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High-Speed Capability: The phenolic cage and 15° contact angle enable a high limiting speed of 103,000 rpm, reducing centrifugal forces and heat generation.
- Superior Rigidity & Load Capacity: The angular contact design provides high rigidity and can support significant combined loads (radial and axial). The dynamic load rating is 3510 lbf.
- Precision Engineering: Manufactured to P4A tolerances with tight dimensional controls on the bore diameter, outside diameter, and width for consistent, high-accuracy performance.
- Universal Matching: The SU designation means bearings can be universally matched in any combination to achieve the desired preload and stiffness without selective assembly.
- Material Quality: Constructed from chrome steel for rings and balls, ensuring high durability, wear resistance, and a long operational lifespan.
7005 CD/P4ADGA Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications, including:
- Machine Tool Spindles (High-speed machining centers, grinding spindles)
- Precision Instrumentation
- High-Frequency Motors
- Medical Equipment (Dental handpieces, centrifuges)
- Aerospace Control Systems
