NTN’s Ultra-Class™ mounted unit line is the original solid base offering in our mounted bearing unit portfolio. It symbolizes our commitment to performance and reliability.

Featuring NTN’s exclusive ball-point set screw design, the Ultra-Class™ black-oxide plated insert provides 120° screw orientation to provide superior alignment and centering, compared to typical 90° configurations. The semi-retractable, ball-point mechanism means excellent tightening torque characteristics without damage to the shaft-mounting surface.

Protection in both wet and dry particle environments is paramount when selecting a mounted unit solution, and the Ultra-Class™ series is up to the task, allowing for usage even in food-grade environments. Using a combined elastomeric seal in tandem with NTN’s outer flinger design, each mounted unit exhibits a fan-like mechanism that keeps particles from getting near the inner ball bearing and raceways.
