S7007 CE/P4ADBG3 Bearing Product Overview & Core Advantages
The S7007 CE/P4ADBG3 is a high-precision duplex angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This matched set bearing features a back-to-back (DB) arrangement and is manufactured to P4A tolerance class, ensuring superior running accuracy. Its primary advantage lies in its ability to accommodate combined radial and axial loads simultaneously while providing high stiffness and stable operation at high speeds, making it ideal for precision spindles and machinery.
S7007 CE/P4ADBG3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| S7007 | Series designation for a high-precision angular contact ball bearing. |
| CE | Indicates a 15° contact angle, optimized for high-speed operation and moderate axial load capacity. |
| P4A | Denotes a super-precision tolerance class (equivalent to ABEC 7), ensuring minimal runout and vibration for high-accuracy applications. |
| DB | Signifies a Duplex Back-to-Back preloaded matched pair. This arrangement provides high moment rigidity and is excellent for withstanding overturning moments. |
| G3 | Specifies the preload level (light preload), which minimizes axial and radial play for precise shaft positioning without excessive friction. |
S7007 CE/P4ADBG3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The duplex back-to-back (DB) arrangement creates a rigid bearing system that can withstand combined radial and axial loads from both directions, as well as significant moment loads. This is critical for maintaining accuracy under complex loading conditions.
- Super-Precision Performance: Manufactured to P4A tolerance class with a 15° contact angle, this bearing delivers extremely low noise, minimal vibration, and exceptional running accuracy, which is essential for high-speed spindles.
- Optimized High-Speed Operation: The phenolic resin cage is lightweight and possesses excellent sliding properties, contributing to lower friction, reduced heat generation, and a high limiting speed of 56,000 rpm.
- Preloaded & Ready-to-Install: Supplied as a matched set with a defined light preload (G3), the bearing eliminates internal clearance, ensuring immediate precision performance and simplifying the installation process.
S7007 CE/P4ADBG3 Bearing Typical Application Areas
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Drives: High-frequency motor spindles and servo drives.
- Robotics: Precision joints and arm articulation systems.
- Medical Equipment: Dental handpieces and high-speed surgical tools.
