nEW launchEs PRODUCTZONE Innovative sealing solutions Trelleborg Sealing Solutions has launched an innovative rotary seal Turcon® RotoGlyd Ring® V, that allows equipment to run faster at high pressure longer. Turcon® RotoGlyd Ring® V is primarily intended for double- acting pressure within severe working conditions that require extended rotary service. The seal is specifically engineered for machinery where a high pressure to velocity value is required to allow equipment to run at the highest possible speeds in high pressures for an extended service life. Turcon® RotoGlyd Ring® V is a premium from 0.5 to 20 MPa. It achieved a PV twice service life is required in demanding service double-acting rotary seal with outstanding as high as other bidirectional seals and conditions. Typical examples are machining performance and reliability. Reduced demonstrated 50 per cent lower friction. centers, hydraulic swivels, lead-troughs, contact surfaces under all operating Furthermore, wear of the seal and O-Ring rotary connections with swivel movements, conditions signifcantly improve friction was so low that it could not be measured. excavators, forestry machinery, hydraulic and wear characteristics without Like other O-Ring activated Slipper Seals, rotators, robots, manipulators, indexing compromising sealing performance. the initial squeeze of the O-Ring ensures tables, pivoting motors, hydraulic motors, Designed for continuous service at high and sufcient contact pressure between seal and blow molding machines, top drives and low PV values, the seal also gives improved mating surface to provide tightness at low core cutting equipment. With maximum performance in oscillating conditions or pressure. With increasing system pressure, recommended operating temperatures of where there are frequent changes in pressure the O-Ring and the seal body direct have +100 °C/ +212 °F (up to +150°C/ +302°F at and/or velocity. a contact force on the sealing surface to lower PV-values), Turcon® RotoGlyd Ring® Henrik Vollmond, Product Manager, ensure sealing efciency at all pressures. V is designed to ft into standard RotoGlyd says: “Customers are demanding increased Turcon® RotoGlyd Ring® V has a built in Ring® grooves. It is available in four cross performance from rotary seals that challenge valve function. Valve ports are made from section series; for shafs in diameters from 35 the PV values of current seals.
