Description

The UNH High Speed Multi‑Sealing Live Center is the high‑speed evolution of the IJN‑type design, delivering 0.003 mm TIR (0.0001") accuracy for demanding CNC applications. Its advanced multi‑sealing system—combining a high‑performance lip seal with a V‑seal—provides exceptional protection against dust and coolant, extending service life and reducing maintenance downtime in automated environments. The heat‑treated point (HRC 60 ± 2) and heat‑treated body ensure strength, rigidity, and long‑term durability. A carbide‑point version (UNHC type) is also available, hardened to HRa 90 ± 5 for superior wear resistance.
