S7007 CDGB/HCP4A Bearing Product Overview & Core Advantages
The S7007 CDGB/HCP4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional rotational accuracy and rigidity. As a universal matchable bearing supplied in a pre-configured set of three, it enables simplified installation and optimal performance in preloaded arrangements. Its core advantages include superior high-speed capability facilitated by a phenolic cage and ceramic balls, a P4A super-precision tolerance for minimal runout, and the ability to handle combined loads efficiently with its 15° contact angle. The sealed design with grease lubrication ensures long-term, maintenance-free operation.
S7007 CDGB/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| S7007 | Basic bearing series and size designation (35mm bore, 62mm OD, 14mm width). |
| C | Specifies a 15° contact angle. |
| DGB | Indicates a Universal Matchable (SU) bearing set. "DB" typically represents a back-to-back mounting configuration, and the "G" denotes a specific preload group. |
| HC | Signifies the use of Hybrid Ceramic components (ceramic balls with steel rings). |
| P4A | Denotes a super-precision tolerance class, tighter than ABEC 7, ensuring extreme running accuracy. |
S7007 CDGB/HCP4A Bearing Structural Features & Performance Benefits
- Hybrid Ceramic Construction: The combination of chrome steel rings and ceramic balls significantly reduces centrifugal forces, lowers operating temperature, and extends bearing life, especially at high speeds.
- Phenolic Resin Cage: This lightweight and robust cage material contributes to lower vibration, reduced friction, and superior performance at the bearing's limiting speed of 56,000 rpm.
- Universal Matching & Preload: Supplied as a matched set of 3 bearings with a Light (Class B) preload, this design delivers high system rigidity, precise shaft positioning, and minimizes deflection under combined radial and axial loads.
- Sealed & Grease-Lubricated: The integral seals protect against contamination and retain the high-performance grease, enabling a maintenance-free solution within the specified temperature range of -30°C to 110°C.
