7026 CDGB/P4A Bearing Product Overview & Core Advantages
The 7026 CDGB/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. As a single bearing with a 15° contact angle and Light Preload (Class B), it is engineered to support high-speed operation while accommodating combined radial and axial loads. Manufactured to a P4A tolerance class, it guarantees superior running accuracy and rotational precision, making it ideal for high-performance spindles and precision machinery.
7026 CDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number 7026 CDGB/P4A provides detailed technical specifications:
- 7026: Basic designation indicating a 130mm bore, 200mm OD, and 33mm width.
- C: Denotes a 15° contact angle.
- D: Indicates the bearing is part of a Universal Matchable (SU) set.
- GB: Specifies a Light Preload (Class B).
- P4A: Identifies the tolerance class, signifying very high precision for both bore and outside diameter.
7026 CDGB/P4A Bearing Structural Features & Performance Benefits
- High Precision and Rigidity: The P4A tolerance class ensures minimal runout and vibration, providing the stability required for ultra-precise applications. The light preload eliminates internal clearance, enhancing system rigidity.
- Optimized for Combined Loads: The 15° contact angle is optimally designed to handle significant combined radial and axial loads simultaneously.
- Superior High-Speed Performance: The lightweight phenolic cage and precision-ground chrome steel components contribute to a high limiting speed of 11,000 rpm, reducing centrifugal forces and operational temperatures.
- Universal Matching Capability: Designed as a Universal Matchable (SU) bearing, it can be universally paired with other bearings from the same lot to form a matched set, simplifying installation and ensuring optimal preload and performance in multi-bearing arrangements.
7026 CDGB/P4A Bearing Typical Application Areas
This precision angular contact bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: Applications in PCB drilling, semiconductor manufacturing, and other high-accuracy processes.
- High-Frequency Motors and Robotic Drives.
- Medical Equipment and Aerospace Instrumentation requiring reliable, high-speed rotation.
