S7010 CD/P4ADBA Bearing Product Overview & Core Advantages
The S7010 CD/P4ADBA is a precision duplex pair of angular contact ball bearings designed for applications demanding exceptional rotational accuracy and rigidity. This back-to-back (DB) arrangement is preloaded to Extra Light / Class A specifications, providing outstanding operational stability and resistance to moment loads. Manufactured to the stringent P4A tolerance class, this bearing set is engineered to handle combined radial and axial loads simultaneously, making it an ideal solution for high-speed, high-precision spindles and machinery where uncompromising performance is critical.
S7010 CD/P4ADBA Bearing Model Code Explained, Specifications & Naming Convention
- S7010: Basic bearing designation (70 Series Angular Contact, 50mm bore, 80mm OD)
- C: 15° nominal contact angle
- D: Duplex bearing pair
- P4A: High precision tolerance class (superior to ABEC 7)
- DB: Back-to-Back mounting arrangement
- A: Extra Light preload classification
S7010 CD/P4ADBA Bearing Structural Features & Performance Benefits
High Rigidity & Precision: The duplex back-to-back arrangement with Class A preload creates a highly rigid bearing system that effectively resists deflection under moment loads, ensuring exceptional running accuracy and system stability.
Superior Load Capacity: With a 15° contact angle and optimized internal geometry, this bearing set efficiently handles combined radial and axial loads in both directions, supported by a dynamic load rating of 10,980 lbf and static load rating of 10,800 lbf.
High-Speed Performance: The phenolic resin cage and precision manufacturing enable a limiting speed of 46,000 rpm, making it suitable for high-speed spindle applications requiring minimal vibration and heat generation.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, this bearing offers excellent wear resistance and durability under demanding operating conditions within a temperature range of -30°C to 110°C.
