| S7024 | Basic bearing series and size designation (120mm bore, 180mm OD). |
| ACD | Angular Contact Design with a 25° contact angle. |
| P4A | High precision tolerance class, exceeding ABEC 7/ISO P4 standards. |
| QBC | Quadruplex Back-to-Back matched set arrangement. |
| B | Specifies a Light preload / Class B. |
S7024 ACD/P4AQBCB Bearing Structural Features & Performance Benefits
- Exceptional Rigidity & Load Capacity: The quadruplex back-to-back (QBC) arrangement creates a highly rigid bearing system capable of supporting heavy combined radial and axial loads from both directions, making it ideal for applications with complex force vectors.
- Precision & High-Speed Capability: Built to P4A tolerance class with a phenolic cage, this set ensures smooth operation, minimal vibration, and is suitable for high-speed applications up to 10,000 rpm.
- Sealed & Lubricated for Longevity: The integral seals protect against contamination, and the bearing is pre-lubricated with grease, offering a wide operating temperature range from -30°C to 110°C and enabling a long, maintenance-free service life.
- Optimized Internal Geometry: Features 22 precision balls of 19.05 mm diameter and a 25° contact angle, balancing high axial load capacity with efficient radial load performance.
S7024 ACD/P4AQBCB Bearing Typical Application Areas
