S7024 ACDGB/P4A Bearing Product Overview & Core Advantages
The S7024 ACDGB/P4A is a super-precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a universally matchable single bearing from a set of three, it excels at accommodating combined radial and axial loads simultaneously. Its P4A tolerance class and light preload (Class B) ensure smooth, quiet operation with minimal runout, making it ideal for high-speed spindles and other high-precision machinery where reliability is paramount.
S7024 ACDGB/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S7024 ACDGB/P4A is decoded as follows:
- S70: Denotes a high-precision bearing series.
- 24: Specifies the bore diameter (120 mm).
- AC: Angular Contact design with a 25° contact angle.
- D: Signifies a phenolic resin cage.
- GB: Indicates universal matchable design, allowing any bearing from a set to be mounted in any position.
- P4A: The tolerance class, representing extremely tight dimensional and running accuracy standards superior to ABEC-7.
S7024 ACDGB/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design and robust construction provide superior stiffness, enabling it to handle significant combined loads. With a dynamic load rating of 24,975 lbf and a static load rating of 26,100 lbf, it offers reliable performance under demanding conditions.
- Optimized High-Speed Performance: The lightweight phenolic cage and 25° contact angle are engineered for stable operation at high rotational speeds, with a limiting speed of 10,000 rpm.
- Precision & Stability: Manufactured to a P4A tolerance class with a light preload, this bearing ensures minimal axial and radial play, resulting in enhanced positional accuracy and reduced vibration.
- Sealed & Lubricated for Life: The sealed design retains factory-applied grease lubrication, protecting against contamination and providing maintenance-free operation within the specified temperature range of -30°C to 110°C.
