Description

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