S7024 ACEGA/P4A Bearing Product Overview & Core Advantages
The S7024 ACEGA/P4A is a precision angular contact ball bearing engineered for applications demanding exceptional accuracy and rigidity. As a single bearing from a universally matchable (SU) pair, it is designed to accommodate combined loads, including significant radial loads and axial loads in one direction. Its P4A tolerance class and extra light preload (Class A) ensure superior running accuracy and minimal deflection, making it ideal for high-speed, high-precision machinery. The sealed design with grease lubrication provides reliable, long-term performance.
S7024 ACEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
- S7024: Basic model number denoting a 120mm bore, 180mm OD, 28mm width angular contact ball bearing.
- AC: Angular Contact design with a 25° contact angle.
- E: Optimized internal geometry for enhanced performance and load capacity.
- GA: Universal Matchable (SU) bearing. "G" indicates a specific axial internal clearance, and "A" denotes a specific preload (Class A/Extra Light) when mounted as a pair.
- P4A: High-Precision Tolerance Class. Exceeds ABEC 7/ISO Class 4 standards, ensuring extremely tight dimensional and running accuracy.
S7024 ACEGA/P4A Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The 25° contact angle and P4A super-precision manufacturing provide excellent rigidity and rotational accuracy, critical for applications like machine tool spindles.
Superior Load Capacity: Engineered to handle combined radial and axial loads simultaneously. The dynamic load rating of 12,150 lbf ensures reliable operation under demanding conditions.
High-Speed Capability: The lightweight phenolic resin cage and optimized internal design contribute to a high limiting speed of 10,000 rpm, reducing friction and heat generation.
Sealed and Pre-Lubricated: The sealed construction with factory-applied grease protects against contamination and provides maintenance-free operation within a wide temperature range of -30°C to 110°C.
S7024 ACEGA/P4A Bearing Typical Application Areas
