Product Overview and Core Advantages
The 7207 CDGA/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and reliability. As a single bearing with universal matching capability (SU), it can be paired with identical bearings to form precisely matched sets. Its extra light preload (Class A) ensures minimal deflection under operational conditions, making it ideal for applications requiring high rotational accuracy and system rigidity. The bearing is pre-lubricated and operates effectively within a temperature range of -30°C to 110°C.
7207 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7207 | Basic bearing series designation (35mm bore, 72mm OD, 17mm width) |
| C | 15° contact angle |
| DG | Universal Matchable bearing (can be paired in any combination) |
| A | Extra light preload (Class A) |
| P4A | High-precision tolerance class (superior to ABEC 7) |
Structural Features and Performance Benefits
Precision Engineering: Manufactured to P4A tolerance class with extremely tight dimensional tolerances (bore/OD: -0.004mm to 0), ensuring exceptional running accuracy and minimal vibration.
Optimized Internal Geometry: Features a 15° contact angle and 13 precision balls with 11.112mm diameter, providing excellent capability for handling combined loads (radial and axial).
High-Speed Capability: The phenolic cage offers superior strength-to-weight ratio and smooth operation at the limiting speed of 41,000 rpm, reducing centrifugal forces and maintaining stability.
Universal Matching Design: As a Universal Matchable (SU) bearing, it can be universally paired with other identical bearings without selective matching, simplifying installation and ensuring optimal preload in multi-bearing arrangements.
