S7014 CE/P4ADBA Bearing Product Overview & Core Advantages
The S7014 CE/P4ADBA is a precision duplex angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This matched back-to-back (DB) arrangement provides superior stability under combined loads, effectively handling radial forces and bidirectional axial loads simultaneously. Manufactured to P4A tolerance class and featuring an extra light preload (Class A), it delivers high running accuracy and is optimized for high-speed operation up to 22,000 rpm. Its compact design and phenolic cage make it an ideal solution for high-performance spindles and precision machinery.

| CE | Matched Bearing Set | Indicates a pre-matched pair of bearings supplied as a set. |
| P4A | Tolerance Class | Denotes high precision levels for dimensional and running accuracy. |
| DB | Duplex Back-to-Back Arrangement | Configuration providing high moment rigidity and stability. |
| A | Preload Class (Extra Light) | Minimal preload for reduced friction and optimal high-speed performance. |
S7014 CE/P4ADBA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back (DB) design creates a wide, rigid support system that significantly increases moment load capacity and operational stability. This configuration is exceptionally effective at handling combined radial and axial loads from both directions.
Optimized High-Speed Performance: The lightweight phenolic resin cage ensures excellent dimensional stability and low friction at high rotational speeds, contributing directly to the bearing's 22,000 rpm limiting speed. The 15° contact angle provides an optimal balance between axial load capacity and speed capability.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore and OD tolerance: -0.004mm to 0), this bearing delivers exceptional running accuracy and minimal vibration. The chrome steel construction of rings and balls ensures high durability and long service life under demanding conditions.
Sealed & Lubricated for Reliability: The sealed design protects against contamination while the factory-applied grease lubrication provides reliable operation across a wide temperature range (-30°C to 110°C), making it suitable for various industrial environments.
