| Code Segment | Technical Meaning |
|---|---|
| 7216 | Basic bearing series, indicating a 80 mm bore, 140 mm OD, and 52 mm width. |
| CD | A Universal Matchable (SU) bearing pair with a specific contact angle and internal design for duplex mounting. |
| P4A | Indicates a high-precision tolerance class with enhanced running accuracy requirements. |
| DGA | Signifies the bearing is lubricated and supplied as a matched set of two bearings. |
7216 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The Universal Matchable (SU) pair, when mounted in a back-to-back or face-to-face arrangement, creates a rigid bearing system capable of handling significant combined loads and moment loads.
- Precision & High-Speed Performance: Manufactured to P4A tolerance class with a phenolic cage, this bearing ensures smooth operation, low vibration, and a high limiting speed of 28,000 rpm, making it an excellent high-speed bearing.
- Optimized Internal Geometry: The 15° contact angle is optimized for applications requiring high axial load capacity alongside radial support.
- Pre-lubricated & Ready for Use: The bearing is factory-lubricated, ensuring immediate, reliable performance upon installation within its specified temperature range of -30°C to 110°C.
