Single passage for all media Patented All-Media technology operates with closed seals for coolant, as a Pop-Off™ when pressure is removed, and as with a microscopic gap between the seals (“controlled leakage”) with pressurized dry air Non-rotating element has a “stroke” (axial movement) of 0.7-3.0 mm, for reliable sealing even with thermal expansion of spindle and variations in 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 Media MQL, Coolant, Air Rotor Connection M16x1.5 LH, 18 mm pilot Air Max.
