2 The information in this product catalog is based on the experience gained in decades of research on the development and manufacture of seals and components for vibration control in the Freudenberg group. It represents the current state of our knowledge. The sealing effect of many products in the catalog is, however, not provided solely by the component. Indeed, in the specific application this effect depends on other parameters such as installation position and contact area, the pressure applied, operating temperature, media to be sealed, lubrication, vibration control-related effects and any ingress of dirt from the outside. This and other, unknown, factors in practical use can have a significant effect on the seals. Against this background, general statements on the function of the products in the catalog are not possible. Information in this catalog only represents recommended values that are not correct in every application. We therefore recommend you to discuss your specific application with our advisory service. In cases with high or special loads, for example due to aggressive media, the seal should be selected in collaboration with us; here trials on reliability are often indispensable. In the context of product optimisation we reserve the right to change, without prior notice, the product range, production sites, products and their manufacturing process as well as the information in this catalog. All previous issues become invalid on publication of this issue of the catalog. Duplication in any form requires express approval from Freudenberg Simrit GmbH & Co. KG, Weinheim, Germany.

6 Elastomers with Excellent Characteristics the Basis of Innovative Solutions Thorough know-how about materials for more than 60 years Simrit has now been developing innovative branded products at the highest level for more than 60 years. With in-depth experience on materials, well-founded knowledge of processing and extensive product know-how, again and again we create ideal pre-conditions for your success. However, the quality of the elastomer material is decisive for the optimum operation of seals and components used in vibration control. Therefore, we are particularly proud of our pioneering role worldwide in this sector. Deliberately targeted development of materials guarantees the highest possible quality and long life More than 250 engineers and chemists worldwide are developing new materials every day for the highest possible functional requirements in joint development ventures with various research institutions plus leading manufacturers of polymers and chemicals. The materials we develop must fulfil the respective customer-specific requirements and withstand all the loadings feasible in their branch of industry both with regard to temperature, pressure and resistance to media and in the presence of static or dynamic loadings. The length of life of our products is constantly being improved by optimising our materials. Constant monitoring on the road to these products becoming mass production materials also guarantees you the highest possible quality. 4

7 The Individual Materials We have Developed are Leaders Worldwide Uniquely wide range of standard materials We produce more than a billion seals annually from a production volume of more than 15,000 tons. When considered as a whole, a range of material, which is unique in its quality and quantity, is available to you with more than 1,500 mixtures of 850 raw materials for your individual applications in seals and vibration control. A large proportion of these are standardised mixtures. Of course, our competent team of experts will advise and assist you fully from the selection of the right materials via the test phase to the start of production. Comprehensive performance package and much more Materials manufactured individually to your wishes and requirements are unusually important in the comprehensive performance package from Simrit. The use of polymers, based on our own raw materials and tailored to your requirements, enables Simrit to develop high performance materials which satisfy the highest functional demands. We use our global materials database for the selection of application-specific materials, which groups together the know-how of our experts, working worldwide, to form a network of top technological services which we can call on at any time. Finally, the appropriate material with the optimum characteristics for your application is manufactured using computer-controlled procedures, from the selection of the raw material to the compounding process. Of course, always adhering to the highest standards in quality and processing and complying with ecological guidelines in the interests of your success and the environment. 5

18 Pre-Selection Pneumatics Pre-Selection Pneumatics Note: The information on minimum operating temperatures is to be considered genaral, as alongside the material, the type of seal, the housing and the operating conditions can also affect the function. The maximum operating temperatures can be exceeded, in this case a reduction in the service life of the seals can be expected. The effect of media (e.g. unsuitable lubricants) can reduce the operating temperature limits.

72 Pneumatics Rod Guides Merkel Guide Strip SF Surface force The pressure distribution on the guide rings is non-linear. The non-linear pressure curve over the contact range was taken into account when calculating the permissible specific surface pressure. The permissible load on the guide strip is calculated by multiplying the projected surface with the permissible specific surface pressure. However, the figure for the permissible specific surface pressure takes into account the possible angular offset of the rods when the recommended guide elements are used. F F H F = P x A H = F / (d x P) H = guide strip width [mm] F = radial loading [N] A = projected area [mm²] P = perm. compression per unit area [N/mm²] d = rod diameter with rod guidance; piston diameter with piston guidance [mm]. 568

The diameter D 1 specified in the table of dimensions is to is to be viewed exclusively in relation to the guide ring. The corresponding diameter of an adjoining seal housing should be tailored to the sealing component.

Cutting rolls to size The following dimensions are available from stock by the metre. The straight length L2 of blanks is to be determined using the formula. The gap k produced after fitting is necessary due to thermal expansion. We recommend a straight cut on the strips. On impact at an angle the tips may be damaged and break-off.

83 Pneumatics Piston Guides Merkel Guide Strip KF Surface force The pressure distribution on the guide rings is non-linear. The non-linear pressure curve over the contact range was taken into account when calculating the permissible specific surface pressure. The permissible load on the guide strip is calculated by multiplying the projected area with the permissible specific surface pressure. However, the figure for the permissible specific surface pressure takes into account the possible angular offset of the piston when the recommended guide elements are used. F F H F = P x A H = F / (d x P) H = guide strip width [mm] F = radial loading [N] A = projected area [mm²] P = perm. compression per unit area [N/mm²] d = rod diameter with rod guidance; piston diameter with piston guidance [mm]. 579
