Rotary Unions
Axial Mechanical Seal Product Features For pressures up to 140 bar at 42,000 rpm
Hydrostatically released axial contact seals Ultra-hard seal rings made from silicon carbide
No coolant leakage after media flow is stopped Robust precision steel housing
Safe for dry operation
Design and Function The ROTODISK S series consists of single channel, axial rotary unions with
hydrostatically released ceramic contact seals and an automatic alignment
compensation system, which ensures that the contact seals always have full
surface contact. The hydrostatic release ensures that the friction moment is
low, which also means that wear is minimal even under high pressure. As a result, ROTODISK S can be operated at pressures of 140 bar and at high speeds
simultaneously. The Micro-Gap System guarantees leakage-free stoppage of
the emulsion flow, as well as safe dry operation. Very long service lives are
achieved through the use of extremely durable contact seals made from silicon
carbide. Spindle or hybrid ball bearings are built into the precision steel housing
and ensure robust, smooth suspension.
Applications
ROTODISK S is mainly used for internal coolant supply in machine tool spindles, transferring the following media: emulsion, oil, water, air or oil-air
mixture. In terms of the high service life requirements of today‘s demanding
performance data, ROTODISK S is more than capable of meeting these requirements, thanks to many years of application. Our products are constantly
under further development, in order to maintain a long service life with everincreasing operating pressures and speeds.
Versions For high speeds, we recommend flexible, vibration-reducing mounting. For
low to average speeds, fixed mounting is a simple, proven solution. Using
contact seals made from carbon graphite, ROTODISK S can also be used for
non-lubricating media. A wide variety of versions is available.
