7007 CE/P4ADBG3GMM2 Bearing Product Overview & Core Advantages
The 7007 CE/P4ADBG3GMM2 is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. This duplex back-to-back (DB) matched set is preloaded and manufactured to P4A tolerance class, ensuring superior running accuracy and dimensional stability. Its primary advantage lies in its ability to handle combined loads (radial and axial) simultaneously with high stiffness, making it ideal for high-precision, high-speed spindles and machinery. The matched set configuration provides a compact, pre-adjusted unit that simplifies installation and guarantees optimal performance.
7007 CE/P4ADBG3GMM2 Bearing Model Code Explained, Specifications & Naming Convention
The model number 7007 CE/P4ADBG3GMM2 provides detailed technical specifications through its suffixes:
- 7007: Basic bearing designation (35mm bore, 62mm OD, 28mm width).
- C: 15° nominal contact angle.
- E: Optimized internal design for high performance.
- P4A: High precision tolerance class exceeding ABEC 7/ISO P4.
- DB: Duplex Back-to-Back mounting arrangement.
- G3: Specific preload level within the matched set.
- GMM: Indicates the use of a phenolic (polyamide) cage.
- 2: Number of bearings in the matched set.
7007 CE/P4ADBG3GMM2 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a rigid bearing system that effectively resists moment loads and supports heavy combined radial and axial loads. The 15° contact angle is optimized for high axial load capacity while maintaining good radial performance.
- Precision & High-Speed Performance: Manufactured to P4A tolerance class with extremely tight dimensional tolerances on bore, outside diameter, and width. The lightweight phenolic cage and optimized internal geometry contribute to lower friction and a high limiting speed of 56,000 rpm, making it a true high-speed bearing.
- Preload & Matched Set Advantages: The bearings are supplied as a factory-preloaded matched pair (G3 preload). This eliminates internal clearance, increases system stiffness, and ensures precise shaft positioning without requiring complex adjustment during installation.
- Material & Construction: Manufactured from high-grade chrome steel for both rings and balls, ensuring high durability and long service life under demanding operating conditions.
7007 CE/P4ADBG3GMM2 Bearing Typical Application Areas
This bearing is engineered for high-performance applications where precision, speed, and rigidity are critical. Key industries and equipment include:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: PCB drilling, engraving, and high-frequency motor spindles.
- Robotics: High-accuracy rotary joints and arm actuators.
- Medical Equipment: Dental handpieces and laboratory centrifuges.
- Aerospace & Defense: Gyroscopes, radar systems, and navigation instruments.
