32916XU NTN Single Row Metric Tapered Roller Bearing Assembly
The NTN 32916XU is a premium, single-row metric tapered roller bearing designed to deliver superior durability and stability under heavy combined radial and thrust loads. Part of the ultra-thin 32900 series, this assembly features a modified boundary design (indicated by the 'XU' suffix) that strictly conforms to ISO international standardization while maintaining a highly compact, light-weight footprint.
Engineered with case-carburized or precision through-hardened steel and equipped with high-performance crowned rollers, it minimizes edge loading to drastically increase system life and operational efficiency. It comes standard with a robust pressed-steel cage that precisely guides the rollers, ensuring optimal performance under extreme temperatures ranging from -40°C to 120°C. This assembly is widely chosen for high-demand power transmission systems, heavy industrial machinery, construction equipment, and automotive drivetrain applications.
