| Code Segment | Technical Meaning |
|---|---|
| 7005 | Basic bearing series, indicating a 25mm bore, 47mm OD, and 24mm width. |
| AC | Angular Contact design with a 25° contact angle. |
| D | Signifies two bearings in a universal matchable (SU) set. |
| P4A | High precision tolerance class, exceeding ABEC 7/ISO P4 standards, with enhanced width and runout tolerances. |
| DGA | Indicates the bearing is pre-lubricated and supplied as a universal matchable pair (SU). |
7005 ACD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double bearing set in a universal match (SU) arrangement provides superior stiffness, enabling stable operation under significant combined radial and axial loads.
- Precision & High-Speed Performance: Manufactured to P4A tolerance class with a phenolic resin cage, this bearing ensures minimal vibration and is capable of high rotational speeds (up to 85,000 rpm greased).
- Optimized Contact Design: The 25° contact angle is optimized to support substantial axial loads in one direction while maintaining excellent high-speed characteristics.
- Ready-to-Install Solution: Supplied as a pre-lubricated, pre-set pair (SU), this configuration simplifies installation, ensures optimal preload, and guarantees immediate, high-performance operation.
