Labyrinth seals - Import export

The corrosion-free material properties mean that the non-contact GMN plastic seals - series S/SA - are particularly well-suited for protecting from watery liquids. Polyoxymethylene has a high resistance to a variety of acids (lactic acids), chemicals and fungi. GMN non-contact plastic seals are approved for the food industry.

Based on decades of experience, GMN has specialized in producing extremely high quality machine tool components. Through this strategy, GMN manufactures a wide range of standard non-contact seals and customized solutions. The frictionless, no-wear characteristics of GMN non-contact seals offer effective, economical and ecological solutions for modern applications in and outside of the machine tool industry. Thanks to the non-contact design of the inner and outer ring, GMN labyrinth seals guarantee completely frictionless operation and therefore offer a wide range of benefits for a whole host of applications and uses.

Metallic materials of the seal components of GMN labyrinth metal seals - series L/M - guarantee highest resistance against coarse and fine contamination.

EWS quality now available for Swiss-type lathes. This new development in driven tools is EWS's response to many customers' requests. The tool systems may appear straightforward at first sight, but their simplicity belies their performance. The design concentrates on the mounting and the spindle concentricity. The requirement profile was developed jointly with an American medical technology company which uses very small drill bits and requires extreme concentricity properties. The spindle bearing technology used with labyrinth seals sets new standards in this field, and is associated with a long service life. Provision has already been made for service. The service centres in Germany, China, Korea and the USA have already been trained in the system and are ready to respond without delay. Third-party brands can also be serviced there at any time.

Lubricating and sealing off tap cocks, labyrinth seals, stuffing boxes and packings Lubricating and sealing off fittings made of metal, plastic and ceramic, e.g. drain, cold- and hot-water fittings Long-term lubrication of heavily loaded press and guide plates, for example on telescope booms of mobile cranes As a lubricant for of threaded spindles on radiator thermostats Advantages and benefits Reduces wear Extension of the relubrication intervals High resistance to oxidation Noise and vibration-damping Resistant to cold and hot water, water vapour, lactic, formic, acetic and fruit acid, as well as alkaline and acidic cleaning agents and disinfectants Good elastomer and plastic compatibility For optimum adhesion, clean contamination and other lubricants from slide surfaces. Best way is to clean mechanically first and then with OKS 2610/OKS 2611 universal cleaner. Apply sufficient paste evenly with a brush, spatula, etc. The paste will also act as a sealant.

For the conveying of gaseous materials. Gas-tight fans If the conveying medium of a fan must not be allowed to penetrate to the outside (e.g. gases that are harmful to health), our fans are equipped with a multi-chamber labyrinth seal on the shaft gland. Depending on requirements, the seals are provided with a sealing gas connection or a grease seal. Under certain circumstances the sealing gas can also be connected to the suction side of the fan. Naturally the flange connections are sealed accordingly and the fan housing is welded gas-tight and tested.

Horizontal and vertical arrangement possible, diameter and length of the pins and dimension A freely selectable, design of the bearing according to specific load, all rolling bearing combinations can be realized, V-ring seal or contactless labyrinth seals While the primary use for our block bearings is in industrial ventilators, they are also increasingly used in other branches of mechanical engineering. Our block bearings are optimally equipped for the requirements of practical application. Take a look for yourself and see the advantages of block bearings over pedestal bearings. Check out the Technical Data Sheets for that.

PAI material considers the most efficient fusible thermoplastic in terms of temperature resistance, chemical resistance and mechanical stress. Its mechanical strength at 205 °C surpasses many engineering plastics at room temperature. BIEGLO offers PAI finished parts of the following types: Torlon® 4203; 4301; 4275; 4435; 4645; 5030 (30% GF); 7130 (30% CF). Each type is best suited for a particular application. Polyamide-imide can be used for a lot of appliations like gears, rollers, plasma chamber hardware and wafer contact fixtures. In addition, PAI material is ideal for high-temperature thermal insulators, burn-in test sockets, valve seats, fasteners, mechanical connections, rollers, labyrinth seals, drive wheels, valve plates, vanes and support gaskets.

The unrestricted availability of energy is playing an increasingly important role. Highly efficient gas or diesel generators, so-called gensets, are used as power generators, e.g. as emergency power generators in hospitals or as temporary power suppliers in areas that are difficult to access. Another area of application is large data centres, where the unrestricted and uninterrupted availability of electricity must be guaranteed. Gensets ensure the power supply in any situation, even under extreme conditions. Our genset gearboxes are connected between the motor and the generator, so that a frequency adjustment for the required power grid is achieved. It is possible to adjust the frequency from 50Hz to 60Hz as well as from 60Hz to 50Hz. The speed transmission is highly efficient, as the single-stage spur gears guarantee a high efficiency of >99%. The use of a labyrinth sealing system also means that the drives require very low maintenance.
