71914 ACDGA/HCP4AL Bearing Product Overview & Core Advantages
The 71914 ACDGA/HCP4AL is a single-row angular contact ball bearing designed for applications demanding high precision and exceptional rotational accuracy. Engineered to primarily accommodate combined loads (simultaneous radial and axial loads), its 25° contact angle provides superior axial load capacity. Manufactured to P4A super-precision tolerance and featuring a ceramic ball and phenolic cage construction, this bearing is optimized for high-speed operation up to 29,000 rpm, offering low friction, high rigidity, and extended service life in demanding environments.

71914 ACDGA/HCP4AL Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The use of ceramic balls significantly reduces friction, heat generation, and wear, enabling higher limiting speeds and longer service life compared to all-steel bearings. This construction also provides superior resistance to electrical erosion.
Phenolic Cage: The lightweight and robust phenolic cage ensures excellent dimensional stability at high speeds, contributing to smooth operation and reduced vibration.
Super-Precision P4A Tolerance: Manufactured to the tightest dimensional and running accuracy standards, this bearing guarantees minimal runout and exceptional rotational precision, which is critical for applications like machine tool spindles.
Universal Matchability (SU): As a Universal Matchable bearing, two identical bearings can be mounted in any arrangement (back-to-back, face-to-face, or tandem) to achieve the required stiffness and load capacity for the application.
High-Speed Capability: The combination of ceramic balls, a phenolic cage, and an open design allows for a very high limiting speed of 29,000 rpm.
71914 ACDGA/HCP4AL Bearing Typical Application Areas
