S7020 CD/P4ADGA Bearing Product Overview & Core Advantages
The S7020 CD/P4ADGA is a precision double-row angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Engineered with an Extra Light (Class A) preload and manufactured to P4A tolerance class, it delivers superior rotational precision and stability. Its double-row design enables it to support substantial combined loads—simultaneously handling radial loads and bidirectional axial loads—making it an ideal, compact solution for high-performance machinery where space and reliability are critical.
S7020 CD/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number S7020 CD/P4ADGA provides detailed technical specifications:
- S70: Denotes a high-precision angular contact ball bearing series.
- 20: Indicates a bore diameter of 100 mm (20 x 5 mm).
- C: Specifies a 15° contact angle, optimized for high-speed operation.
- D: Signifies a Universal Matchable (SU) design, allowing bearings to be paired in a universal arrangement.
- P4A: The tolerance class, indicating very high dimensional and running accuracy.
- DGA: Specifies the preload grade; in this case, Extra Light (Class A).
S7020 CD/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double-row angular contact structure provides high rigidity and can support significant combined radial and axial loads from both directions.
- Precision & Speed: Manufactured to P4A tolerance class and featuring a phenolic resin cage, this bearing is built for high-speed applications with a limiting speed of 10,000 rpm.
- Universal Matching: The Universal Matchable (SU) feature allows two bearings to be mounted in a universal arrangement, simplifying installation and ensuring optimal preload and performance.
- Durability & Reliability: Constructed from chrome steel for both rings and balls, it offers excellent wear resistance and a long operational life under demanding conditions.
