Description

The BNN/BNNC Draw‑Off Nut Live Center provides 0.003 mm TIR (0.0001") accuracy and is suitable for both CNC and conventional machines. Its draw‑off‑nut design allows for easy release from the tailstock, improving operator convenience and workflow efficiency. The heat‑treated point (HRC 60 ± 2) ensures durability, while a high‑performance lip seal and deflected‑shaft design protect the double angular contact bearing assembly from dust and coolant intrusion. The heat‑treated body adds strength, rigidity, and long service life. A carbide point option is also available, hardened to HRa 90 ± 5 for superior wear resistance.
