1129 Series Bearingless “Pop-Off”
Rotating Unions for Coolant Service
• Single passage for coolant or MQL
• Patented “pop-off” technology allows unlimited dry running
without media pressure
• Pop-off stroke of 0.7-3.0 mm compensates for thermal
expansion of spindle during extended operation as well as
variations in drawbar position
• Full-flow design has no obstructions to trap chips or debris
• Balanced mechanical seals made from silicon carbide for
long life even under difficult operating conditions
• Anodized aluminum housing resists corrosion
