S71914 ACDGC/P4A Bearing Product Overview & Core Advantages
The S71914 ACDGC/P4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. This sealed bearing features a universal matchable (SU) design, allowing two bearings to be mounted in a tandem, back-to-back, or face-to-face arrangement to optimize performance for specific load conditions. Its key advantages include the ability to handle combined loads (radial and axial loads simultaneously), a moderate preload (Class C) for enhanced stiffness, and a P4A tolerance class for superior running accuracy. The phenolic cage and sealed construction contribute to reliable, high-speed operation.

S71914 ACDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity & Preload: The moderate preload (Class C) eliminates internal clearance, providing high system rigidity and precise shaft positioning, which is critical for minimizing deflection under load.
- Superior Load Capacity: The 25° contact angle and robust construction enable the bearing to efficiently support significant combined radial and axial loads.
- High-Speed Performance: The lightweight phenolic cage ensures stability and reduces centrifugal forces, allowing for a high limiting speed of 28,000 rpm. The integral seals retain lubricant and protect against contamination.
- Precision & Longevity: Manufactured to P4A tolerance standards, this bearing guarantees smooth, quiet, and vibration-free operation. The sealed design with factory-applied grease lubrication offers long-term, maintenance-free service within a wide temperature range.
