ROTRY UNIONS STNDRD VRINTS OVERVIEW SECURE TRNSFER OF LL MEDI OTT-JKOB rotary unions ensure the reliable transfer of cooling luids and gases into the rotating spindle, from where they are passed through to the tool holder and directly to the cutting edge. Media typically used include hydraulics, air, and MQL. side from that, OTT-JKOB ofers rotary unions for internal spindle cooling as well as for cryogenic machining. STNDRD VRINTS SINGLE-PSSGE OIL / DUL-PSSGE With a product range consisting of more than variants, we are able to provide solutions for the most common areas of application. In addition, 1 special rotary unions are available to meet special machining requirements. s part of the modular product range, our rotary unions perfectly harmonize with the power drawbar, thus allowing problem-free subsequent integration or retroitting of existing applications. OPTIML VILBILITY OF YOUR ROTRY UNION Malfunction or failure of the rotary union can result in expensive total spindle failure. To prevent such situations, OTT-JKOB provides diferent options to monitor the rotary union s function by using sensor technology.

EXTERNL LEKGE MONITORING OUR SERVICE RELIBLE LEKGE DETECTION With external monitoring, the sensor is positioned in a measuring device connected to the rotary union by a tube. If the predeined low limit is exceeded inside the tube, a signal is emitted which appears directly on the measuring device or which can be sent to the machine control system. sensor connector entrance and exit interchangeable signal alarm signal operating voltage SPECIL ROTRY UNIONS In addition to our standard rotary unions, our product range includes a huge number of rotary unions designed for special technical requirements, such as: For abrasive media (e. g. l-si alloys) For glass and stone processing For cryogenic machining (CO 2 ) For internal mixing MQL systems For higher pressure For higher speeds For special housing designs 2x hose coupling for hose d = 6 mm (included) G 1/8 G 1/8 mode switch (No. 1) Our team of experts is available to advise you on the optimal solution for your applications. REPIR The external monitoring can be added at a later date without replacing the rotary union and is also designed for use with rotary unions from third-party manufacturers. Rotary unions are high-tech clamping system components. In case of defect and wear, the OTT-JKOB service team ensures with an individual range of repair services optimal availability and functionality of your rotary union. Repaired rotary unions are subject to the same warranty as new parts. FETURES designed to detect leaking, hydraulic oil and water. preset and calibrated for intended medium adjustable modes: wear detection or failure detection continuously monitoring of the low rate wear-free operation no bottleneck and without backwash installation in any location (entrance and exit interchangeable) simple signal processing via 24 V switch output Subject to modification due to technical advance! 23
