S7024 ACD/P4ADGB Bearing Product Overview & Core Advantages
The S7024 ACD/P4ADGB is a high-precision double row angular contact ball bearing designed for demanding applications requiring exceptional accuracy and rigidity. Engineered to a P4A tolerance class, it excels in handling combined loads—simultaneously supporting significant radial loads and axial loads in both directions. Its compact design, featuring a universal matchable (SU) configuration, allows for simplified mounting and high system rigidity. Pre-loaded with grease and sealed for life, this bearing offers reliable, maintenance-free operation in high-speed and high-precision environments.
S7024 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
- S7024: Basic designation indicating a double row angular contact ball bearing with a 120mm bore and 180mm outside diameter.
- ACD: Signifies a 25° contact angle and a specific internal design optimized for high rigidity and load capacity.
- P4A: Denotes an extremely high precision tolerance class, exceeding ABEC 7 standards, for superior running accuracy and low vibration.
- DGB: Indicates a universal matchable (SU) arrangement. Two bearings can be mounted in any combination (back-to-back, face-to-face, or tandem) without pre-set axial clearance, simplifying installation and providing design flexibility.
S7024 ACD/P4ADGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design and 25° contact angle provide superior rigidity, enabling the bearing to effectively handle heavy combined radial and axial loads from any direction. This makes it ideal for applications where shaft deflection must be minimized.
High-Speed Performance: The lightweight, robust phenolic resin cage ensures stable operation at high speeds, contributing to the bearing's impressive limiting speed of 10,000 rpm. The optimized internal geometry further enhances high-speed capability.
Precision & Longevity: Manufactured to P4A precision standards, this bearing guarantees exceptional running accuracy and low noise. The phenolic cage and pre-greasing with high-quality lubricant ensure smooth operation and a long service life within the specified temperature range of -30°C to 110°C.
