Rotary Unions For High Speed, Coolant, MQL, Air, and Dry Run – Series BH

Description The rotary unions of the model BH have been designed for machine tool spindles operating at high speed with fluid (coolant, air, or MQL) passing through or for dry operation when needed. The seals, balanced and microlapped, remain closed and effective both during wet runs (with fluid passing through) and dry runs (without fluid), ensuring long-lasting performance without issues.
