71816 ACD/P4TGB Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The angular contact design with 25° contact angle provides optimal stiffness and enables efficient handling of combined radial and axial loads. With a radial dynamic load rating of 6660 lbf and static load rating of 11475 lbf, this bearing delivers reliable performance under demanding conditions.
High-Speed Performance: The phenolic cage (TGB) ensures stable operation at high rotational speeds, supporting a limiting speed of 28,000 rpm. This makes the bearing suitable for high-speed applications where minimal vibration and precise rotation are essential.
Precision Engineering: Manufactured to P4 tolerance class with tight dimensional tolerances on bore, outside diameter, and width, this bearing guarantees exceptional running accuracy and consistent performance in precision applications.
Universal Matching Capability: The Universal Matchable (SU) design allows for flexible arrangement in sets of three bearings, enabling optimal preload configuration for specific application requirements.
