71916 ACDG/HCP4ALG30 Bearing Product Overview & Core Advantages
The 71916 ACDG/HCP4ALG30 is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and performance. This single bearing features a 25° contact angle and is supplied as part of a universally matchable (SU) set, allowing for flexible preloaded arrangements. Its core advantages include the ability to accommodate combined radial and axial loads, superior high-speed capabilities with a limiting speed of 17,000 rpm, and outstanding rigidity due to its optimized internal geometry and ceramic ball construction. This bearing is pre-lubricated and built to P4A tolerance class, making it ideal for high-reliability, precision machinery.

71916 ACDG/HCP4ALG30 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Design: The use of ceramic balls significantly reduces weight and centrifugal forces, contributing to lower operating temperatures and higher limiting speeds. This material combination also offers improved resistance to wear and a longer operational life.
Phenolic Cage: The lightweight and robust phenolic cage ensures stable ball guidance and excellent performance at high rotational speeds, contributing to the bearing's overall high-speed capability.
High Rigidity & Load Capacity: The 25° contact angle and precision-ground raceways provide high rigidity, enabling the bearing to effectively handle combined loads (radial and axial). With a dynamic load rating of 7762 lbf and a static load rating of 8212 lbf, it is built for demanding applications.
Precision & Preload Ready: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration. As a universally matchable (SU) bearing supplied in a set of 3, it is designed for simplified assembly into preloaded configurations, enhancing system stiffness and accuracy.
