Freudenberg Simrit GmbH & Co. KG | Technical Manual 2007

The information in this product catalog is based on theexperience gained in decades of research on the deve-lopment and manufacture of seals and components forvibration 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 otherparameters such as installation position and contactarea, 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 canhave a significant effect on the seals.

Against this background, general statements on thefunction of the products in the catalog are not possible.Information in this catalog only represents recommen-ded values that are not correct in every application.We therefore recommend you to discuss your specificapplication with our advisory service. In cases with highor special loads, for example due to aggressive media,the seal should be selected in collaboration with us;here trials on reliability are oen indispensable.

In the context of product optimisation we reserve theright to change, without prior notice, the product range,production sites, products and their manufacturing pro-cess as well as the information in this catalog.

All previous issues become invalid on publication of thisissue of the catalog.

Dear Reader,

This first issue of the Simrit Tech-

nical Manual outlines our tech-nological expertise, gained overdecades of experience regardingall aspects of seal and vibrationcontrol technology, in a conciselylaid out reference book.

Complementary to the 5 Simritproduct catalogs, in which you canfind 26,000 catalog items, this refe-rence book encompasses valuable

technical fundamentals of materialsas well as applications and designtypes on through to FEM simulationprocesses for Simmerrings androtary seals, seals for fluid power,O-rings and static seals, specialsealing products and for vibrationcontrol.

This Technical Manual servesdesign engineers, developersand researchers, just as well asuniversities and other technicallyoriented institutions, as a lexiconfor all topics regarding the pro-perties of elastomer materials,engineering product designs orthe selection and identification ofrelevant operating conditions for

seals and vibration control-relatedproducts. It is based on the esta-blished technical fundamentals ofthe Simrit catalog, which has beencompletely revised and expandedaccording to the newest findingsof our worldwide research centres.Numerous diagrams, photographicdocumentation and elaborate 3D-models of application examplesvividly explain deployment factors

and dimensioning.

A DVD with all 5 available Simritproduct catalogs, the TechnicalManual, 3D-CAD geometries,FEM simulations and much more,completes the wide range of infor-mation of this reference work.

We are certain that the TechnicalManual will make a valuable con-

tribution towards resolving yourseal and vibration control-relatedissues. If you require more detailedinformation, then please contactyour Simrit customer support spe-cialist or a Simrit Preferred Distribu-tor in your area.
