Description

The rotary M.C.T. union is intended for machine tools applications for the transfer of fluids (such as oil and air) to and from rotating shafts for air and hydraulic chuck, brakes, clutches, etc. The type of rotary seal fitted to this model is a Filton® Balanced Mechanical Seal containing multiple helical coil springs. The seal face materials are normally carbon against stainless steel. For applications on machine tool coolants where traces of abrasive particles may be present, tungsten carbide seals are also available. Rotary sealing is created by relative rotation between extremely flat sealing faces (see item #2 and #4 in diagram) held in contact by the helical coil springs and the additional sealing force created by the pressure of the fluid passing through the union. The bearings fitted to the union are a matched pair of pre-loaded angular contact bearings lubricated for life with a special grease. A double range of M.C.T. unions is offered with the machine end connection having parallel pipe threads (RH or LH) for speeds up to 1,500 r.p.m. and with an additional concentric locating spigot for speeds up to 3,000 r.p.m. The M.C.T. union is available in nominal sizes including 8(1/4”), 10(3/8”), 15(1/2”), 20(3/4”) and 25(1”) with three variations including a single flow Type B.E., a double flow stationary tube Type S.T. and a double flow rotating tube Type R.S.
