Description:

The OTT-JAKOB 95.250.041.2.0 is a single-passage rotary union used to transfer media from the fixed supply to the rotating drawbar of a machine tool spindle. It is mounted in OTT-JAKOB unclamping units and feeds MQL oil-air mixture, air or coolant through the power drawbar. The GD type family features permanently closed sealing surfaces that are compatible with all conventional media and allow unlimited dry machining while keeping leakage to a minimum. Integrated hybrid bearings have a low friction coefficient and long grease service life, ensuring reliable function at high speeds, and a labyrinth seal effectively protects the bearings against contamination. The coolant connection can be rotated through 360° to simplify installation.

Typical applications include coolant feed through the drawbar of high-speed machining spindles, air purging and chip evacuation lines, hydraulic unclamping supply for tool clamping systems, and retrofit or replacement of rotary unions in OTT-JAKOB unclamping units on CNC machining centres.
