7026 CD/P4A Bearing Product Overview & Core Advantages
The 7026 CD/P4A is a single-row angular contact ball bearing designed for high-precision applications requiring exceptional rotational accuracy and rigidity. Engineered to P4 (ABEC-7) tolerance class, this bearing excels at accommodating combined loads, primarily thrust loads in one direction, while maintaining superior performance at high speeds. Its phenolic resin cage and optimized internal geometry contribute to low friction, high limiting speeds, and stable operation, making it an ideal choice for demanding machine tool spindles and other precision machinery.
7026 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7026 | Basic bearing designation: 130 mm bore, 200 mm OD, 33 mm width. |
| CD | Indicates a specific contact angle of 15° and optimized internal design for high-speed operation and rigidity. |
| P4A | Denotes a high-precision tolerance class (P4 / ABEC-7) with specific running accuracy requirements. |
7026 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: Manufactured to P4 tolerance class with tight dimensional control (bore tolerance: -0.01mm to 0), ensuring minimal runout and vibration for superior positional accuracy.
- Optimized Load Capacity: The 15° contact angle is engineered to efficiently handle high thrust loads in one direction while supporting significant radial loads.
- High-Speed Capability: The lightweight and robust phenolic resin cage minimizes centrifugal forces and ensures stable operation at the high limiting speed of 10,000 rpm.
- Pre-Lubricated & Ready-to-Use: The bearing comes pre-lubricated, facilitating immediate installation and initial operation within its specified temperature range of -30°C to 110°C.
7026 CD/P4A Bearing Typical Application Areas
This precision angular contact bearing is predominantly used in applications demanding high speed, accuracy, and rigidity, including:
- Machine Tool Spindles (milling, grinding, and turning centers)
- High-Frequency Motors and Spindles
- Precision Gearboxes
- Medical and Laboratory Equipment
- Aerospace Control Systems
