1139-032-327 – Deublin Union, Bearingless All-Media, M12X1.25 LH, 14 MM Pilot, 3/8″ PT

Single passage for all media

Patented All-Media technology operated with closed-seals for coolant, as a Pop-Off when pressure is removed, and as a microscopic gap between the seals (“controlled leakage”) with pressurized air

Non-rotating element has a “stoke” (axial movement) of 0.7-3.0 MM, for reliable sealing even with thermal expansion of spindle and variations of drawbar position

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
