S7010 CB/P4ADGA Bearing Product Overview & Core Advantages
The S7010 CB/P4ADGA is a precision double row angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. As a P4A tolerance class bearing, it offers superior dimensional and running accuracy. Its universal matchable (SU) design allows for flexible mounting arrangements in pairs to support combined loads, handling significant radial loads and bidirectional axial loads simultaneously. The combination of a phenolic cage, high-grade chrome steel, and extra light preload (Class A) makes it an ideal solution for high-speed spindles and other precision machinery where high rigidity and minimal deflection are critical.
S7010 CB/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
The model number S7010 CB/P4ADGA decodes the bearing's specific technical features:
- S70: Denotes a series of high-precision angular contact ball bearings.
- 10: Indicates a bore diameter of 50 mm (10 x 5 = 50 mm).
- CB: Specifies a 15° contact angle and Universal Matchable (SU) design, allowing bearings to be mounted in pairs in any configuration (back-to-back, face-to-face, or tandem).
- P4A: Identifies the tolerance class, specifying extremely tight dimensional and running accuracy superior to ABEC 7 / ISO P4.
- DG: Signifies that the bearing is pre-filled with a grease lubrication.
- A: Denotes the extra light preload (Class A) applied to the bearing set, minimizing friction and heat generation at high speeds.
S7010 CB/P4ADGA Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides a significantly stiffer support structure compared to single row bearings, enabling it to withstand substantial combined radial and axial loads from both directions with minimal deformation.
- Superior High-Speed Performance: The lightweight phenolic resin cage ensures stability and reduces centrifugal forces, contributing to a high limiting speed of 46,000 rpm. The 15° contact angle and extra light preload are optimized for high-speed operation with low friction and heat generation.
- Precision & Longevity: Manufactured to P4A tolerance class with chrome steel rings and balls, the bearing guarantees smooth, quiet, and precise running. The sealed construction with pre-applied grease protects against contamination and provides long-term, maintenance-free operation within a temperature range of -30°C to 110°C.
S7010 CB/P4ADGA Bearing Typical Application Areas
