71914 CE/HCP4ALDGA Bearing Product Overview & Core Advantages
The 71914 CE/HCP4ALDGA is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This universally matchable (SU) bearing is designed to accommodate combined loads (radial and axial) simultaneously, featuring a 15° contact angle and extra light preload (Class A) for optimal rigidity and minimal deflection. Its construction with ceramic balls and phenolic cage enables superior high-speed capabilities and reduced rotational mass, making it ideal for high-reliability, precision machinery.

71914 CE/HCP4ALDGA Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings with silicon nitride ceramic balls provides superior performance characteristics including reduced friction, higher stiffness, and extended service life under demanding conditions.
High-Speed Capability: The phenolic resin cage offers excellent strength-to-weight ratio and dimensional stability at high speeds, contributing to the bearing's impressive limiting speed of 24,000 rpm. The ceramic balls' lower density reduces centrifugal forces, further enhancing high-speed performance.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional control (bore and OD tolerance: -0.004mm to 0), this bearing ensures minimal runout and vibration for precision applications.
Universal Matching Design: As part of a universally matchable (SU) set, these bearings can be arranged in various configurations (back-to-back, face-to-face, or tandem) without requiring selective assembly, simplifying installation and maintenance.
Optimized Load Capacity: With a radial dynamic load rating of 8,055 lbf and radial static load rating of 7,200 lbf, the bearing delivers reliable performance under combined loading conditions.
