Spring Energised seals are single acting seals which are used for dynamic and static applications.They are effective in a wide range of applications. They are chosen when higher resistance to chemical media is required, if the seal is required to operate in extremes of temperature and where good extrusion and compression characteristics are needed.

1. Application specific U-shaped seal profile2. Spring geometry suited to the particular application3. Proven high-performance polymers

Standard products are available from 2 mm up to 2500 mm (8' 2") in diameter along with custom Manufactured intermediate sizes, inch (imperial) sizes or special geometries.

All seals have the same operating principle and differ only in their profile form and type of metallic spring used. The spring supplies the load required for sealing at low pressures. The "U" shaped jacket allows fluid pressure to energize the sealing lips, so total sealing pressure rises with increasing operating pressure Spring Force.

The different types of seal combined with the properties of materials offer design engineers a wide range of solutions to a large number of applications. The most important characteristics of Spring Energised Seals are listed below:Very low coefficient of frictionGood dynamic and static sealingCapable of sealing at high speeds up to 15 m/s (49 ft/sec)Almost universal chemical compatibilityOperating temperature of -253 C up to +300 C (423 F to 572 F)Very good thermal resistancePermanent elasticity unaffected by contact with chemicalsGood ageing characteristicsLow compression setCapable of withstanding high pressures above 200Mpa (2000 bar, 29000 psi) when using Back-up RingsVery good dry-running properties

Spring Energised seals offer major benefits in the design of components such as hydraulic and pneumatic cylinders, in all industries.

These include:Excellent leak tightnessHigh resistance to wearNo extrusion into gapsWithstanding aggressive and abrasive process mediaVery good temperature capabilitiesLow frictionCompact formSimple installation

These seals are available in a range of geometries and designs that allow the optimum profile to be selected for each application. They can be produced from a wide range of PTFE based compounds. These are specially formulated for sealing elements and offer superior characteristics specifically matched to the demands of our customers. When required, Spring Energised seals can also be manufactured in polyethylene based material. To choose the best seal for your application, you must first decide the functional parameters. It is also important to consider the quality of the mating surface, which has a significant effect on the function and service life of the sealing system.

1 - Could be provided by kilogram or meter2 - High abrasion resistance, wide range of application temperatures3 - Low friction, high efficiency4 - Stick-slip free starting, no sticking5 - Easy installation

The widest product range in the sector Due to their elastomer sealing lip, standard radial shaft seals have only a limited application range with respect to pressure , temperature and media loads.High performans sealing lips made from modified PTFE , cause very low friction , thanks to their stick-slip-free running , suffer little wear and tear, reducing the heat development and permitting higher peripheral speeds.

1 - Low friction seal material2 - Low and high temperature range (-60 to +260 C3 - High pressure capability (up to 25 bar )4 - High speed ability ( 40 m/s )5 - Outstanding resistance to chemical media6 - Fits Standard oil seal installation groove.

Given the many different needs involved in practical applications, TOKEZ offers users many different product versions , ranging from standard one lip , ready to-install , available from stock; right through to customized special designs.
