7014 ACDGA/P4A Bearing Product Overview & Core Advantages
The 7014 ACDGA/P4A is a single-row angular contact ball bearing engineered for high-precision applications requiring exceptional rotational accuracy and rigidity. Designed to accommodate combined loads (radial and axial loads in one direction), this bearing features an extra light preload (Class A) for minimal friction and optimal performance in high-speed operations. Manufactured to P4A tolerance class, it delivers superior dimensional stability and running accuracy, making it ideal for machine tool spindles and other precision machinery where reliability is critical.
7014 ACDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle for optimal axial load capacity. |
| DGA | Universal Matchable (SU) bearing, supplied in sets of 3 for precise preload configuration in matched arrangements. |
| P4A | High-precision tolerance class ensuring tight dimensional control (bore/OD tolerance: -0.004mm to 0) for superior running accuracy. |
7014 ACDGA/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Precision: The single-row angular contact design with a 25° contact angle provides excellent rigidity and axial load capacity. Manufactured to P4A tolerance standards, it ensures minimal runout and vibration for precision applications.
- Optimized High-Speed Performance: The phenolic cage reduces centrifugal forces and friction, enabling a limiting speed of 29,000 rpm. Combined with factory lubrication, it supports smooth operation at high rotational speeds.
- Superior Load Capacity: With a dynamic load rating of 10,980 lbf and static load rating of 9,900 lbf, it reliably handles combined radial and axial loads in demanding environments.
- Universal Matching Capability: Designed as a Universal Matchable (SU) bearing, it can be supplied in sets (3 bearings) for precise preload adjustment in duplex or triplex configurations, enhancing system stiffness and accuracy.
7014 ACDGA/P4A Bearing Typical Application Areas
- Machine Tool Spindles: High-precision machining centers and grinding spindles requiring P4A tolerance and high-speed capability.
- Precision Instrumentation: Measuring equipment and optical devices where minimal vibration and high accuracy are critical.
- High-Speed Motors & Pumps: Applications demanding reliable performance at elevated rotational speeds.
- Aerospace & Defense Systems: Guidance systems and actuators requiring strict tolerance control and durability.
