1154-003-137 - Union

Union, compact, bearingless, autosense, M12 × 1.25 LH, 13 mm pilot. Single passage for coolant or MQL. Patented autosense technology changes automatically between closed seals and controlled leakage operation in response to the kind of media. Non-rotating element has “stroke” (axial movement) of up to 8 mm, to track drawbar movement even when the union is mounted on the clamping device. Full-flow design has no obstructions to trap swarf or debris. Balanced mechanical seals made from silicon carbide for long life even under difficult operating conditions. Anodized aluminum housing resists corrosion.
