S7207 CD/P4A Bearing Product Overview & Core Advantages
The S7207 CD/P4A is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. Engineered to accommodate combined loads (simultaneous radial and axial forces), this single-row bearing features a 15° contact angle for optimal axial load capacity. Manufactured to P4 (ABEC-7) tolerance class, it ensures minimal runout and vibration, making it ideal for high-speed spindles and other precision machinery. Its compact design, combined with high-grade materials and a phenolic cage, delivers reliable performance in demanding operational environments.
S7207 CD/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7207 | Basic bearing designation (35mm bore, 72mm OD, 17mm width) |
| CD | Specific internal design and contact angle (15° in this case) |
| P4A | Indicates high precision tolerance class (P4/ABEC-7) with specific accuracy requirements |
S7207 CD/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The optimized 15° contact angle and robust construction provide excellent resistance to combined loads, ensuring stable operation under demanding conditions.
- Precision Performance: Manufactured to P4 tolerance class with tight dimensional control (bore: -0.006mm to 0), guaranteeing high running accuracy and minimal vibration for precision applications.
- High-Speed Capability: The lightweight phenolic resin cage reduces centrifugal forces, enabling a high limiting speed of 20,000 rpm while maintaining dimensional stability.
- Sealed & Lubricated Design: The sealed construction with factory-applied lubrication protects against contamination and provides long-term, maintenance-free operation within a wide temperature range (-30° to 110°C).
- Superior Material: Components made from chrome steel offer high hardness and wear resistance, contributing to extended bearing service life.
