7007 CE/HCP4AL1DT Bearing Product Overview & Core Advantages
The 7007 CE/HCP4AL1DT is a high-precision duplex tandem angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This matched bearing set features a P4A super-precision tolerance class and is preloaded for immediate use. Its core advantages include superior high-speed capability enabled by a phenolic cage and ceramic balls, excellent running accuracy, and the ability to handle significant combined loads (axial and radial) due to its angular contact design and duplex tandem arrangement, which provides high axial rigidity in one direction.
7007 CE/HCP4AL1DT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7007 | Basic bearing series and size designation (35mm bore, 62mm OD). |
| CE | Internal design code, optimized for high-speed operation. |
| HC | Indicates the use of Hybrid Ceramic balls (Silicon Nitride). |
| P4A | Specifies the super-precision tolerance class, exceeding ABEC 7/ISO P4. |
| L1 | Light preload designation for the matched set. |
| DT | Indicates a Duplex Tandem arrangement, where two bearings are mounted to increase axial load capacity in one direction. |
7007 CE/HCP4AL1DT Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic (Si3N4) balls significantly reduces centrifugal forces, lowers operating temperature, and extends service life, especially at high rotational speeds (up to 56,000 rpm).
- Phenolic Resin Cage: This lightweight and robust cage material offers excellent dimensional stability and low friction, further contributing to the bearing's exceptional high-speed performance and smooth operation.
- Duplex Tandem (DT) Arrangement: The two bearings are manufactured and supplied as a pre-loaded matched set. This configuration provides maximum axial rigidity and load-carrying capacity for applications with heavy thrust loads in a single direction.
- Super-Precision P4A Tolerances: Ensures minimal runout and superior running accuracy, which is critical for applications like machine tool spindles and other high-precision machinery.
- Open & Pre-lubricated Design: The open seal type allows for optimal lubrication management in controlled environments, while the factory-applied lubricant ensures immediate operation.
7007 CE/HCP4AL1DT Bearing Typical Application Areas
