S7014 CE/P4ADGA Bearing Product Overview & Core Advantages
The S7014 CE/P4ADGA is a precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As a universal matchable (SU) bearing supplied in a pre-matched pair, it delivers superior performance in handling combined radial and axial loads. Manufactured to P4A tolerance class with an extra light preload (Class A), this bearing is engineered for high-speed operation, precise positioning, and long-term reliability in critical machinery.
S7014 CE/P4ADGA Bearing Model Code Explained, Specifications & Naming Convention
- S7014: Basic bearing series and size designation (70mm bore, 110mm OD, 40mm width)
- CE: Indicates a universal matchable bearing pair with controlled axial clearance
- P4A: Denotes super precision tolerance class with specific running accuracy requirements
- DG: Signifies the bearing is supplied as a universal duplex pair (DB/DF configuration)
- A: Represents extra light preload (Class A) for minimal deflection under light loads
S7014 CE/P4ADGA Bearing Structural Features & Performance Benefits
High Precision Construction: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring exceptional running accuracy and dimensional stability.
Optimized Load Capacity: The 15° contact angle and double-bearing universal match configuration provide excellent capability for handling combined radial and axial loads, with dynamic load rating of 8775 lbf and static load rating of 8212 lbf.
High-Speed Performance: The phenolic cage and precision engineering enable a limiting speed of 22,000 rpm, making it suitable for high-speed applications requiring minimal vibration.
Thermal Stability: The phenolic cage material and chrome steel construction maintain dimensional stability across the operating temperature range of -30°C to 110°C.
Precision Matching: As a universal matchable (SU) bearing supplied in a pre-matched pair, it ensures optimal performance without additional selection or adjustment requirements.
